First Grade Math Warm-Ups: Week of February 17-20, 2015

I feel like I keep saying how short the weeks are lately, but hey, I’ll say it again–this week was another short one, where I only have a few warm-ups to share.  They were particularly good ones (in my opinion, of course!) because they really got my kiddos thinking about strategies.  We’re still working on addition, but the focus has now shifted a bit to choosing the strategy most appropriate to the numbers–not just the strategy that is your favorite one.  Compensation was a particular one we worked on over the last few days.

Tuesday

CAM01613Ok, so I misspoke a little bit–we’re mainly focusing on addition, but continuing to tie our work to subtraction, so that kiddos can see the connections.  This one was also meant to introduce them to the word DIFFERENCE (we did SUM last week).

Wednesday

CAM01642We’ve been working on flexibility, too, although for most kiddos, one strategy is as far as they’ve gotten so far.

Thursday

CAM01643While they only have to add within 100, there are many who are ready to apply their strategies to bigger numbers.  This one gave them the chance to try it out!

Friday

CAM01653

I mentioned choosing the strategy for the numbers, and this one was made for using compensation (making one number a “friendly” one–like a 10–so that it’s easier to answer.  Usually you can use mental math.)!  And can you tell I got a new box of markers in the mail this week?  🙂

Also, I’ve been toying the idea of finally moving my warm-ups to Padlet, as we all have iPads now.   I’ve always valued the way we can save the post-its and charts by doing it this way, and refer to the problems again if we need to, but I might be rethinking my previous choice.  With 1st graders, I wonder if less “stuff” around might be a better way to go.  We could still refer, and it might be easier to share with others.  Any ideas, friendly blog readers? 🙂

First Grade Math Warm-Ups: Week of February 9-12, 2015

Is there ever a week in January or February when we have all 5 days?  This was another short one (and one filled with a party), so there are only 3 warm-ups this week.  As I’ve mentioned previously, we’re continuing to work on addition within 100, grouping around place value and making sense with our explanations.  Enjoy!

First Grade Math-Warm Ups: Week of February 2-6, 2015

Seems like I am always giving a reason for why our week was crazy.  This week was the same way!  Wednesday we participated in Global School Play Day, so didn’t have math, and yesterday my 3-times-longer-than-usual commute (because of snow and ice on the road) meant that I didn’t get to school in time to write one, and then add in our first day with our iPad Minis yesterday as well and VOILA, you’ve got crazy!  See what I mean?  But hey, there were 3 warm-ups this week, so here we go!

Monday

It only seemed right to have a Super Bowl themed warm-up the morning after the big game!  Still working on adding 2-digit numbers efficiently with this one. 🙂

CAM01522

Tuesday

The problem yesterday actually brought up a great (but unexpected question) as a friend only read the first sentence and then assumed she knew what it was asking.  She thought that it was asking her to SUBTRACT the numbers because she figured the last part asked by how many points the Patriots had won.  We were able to talk about how important reading the whole problem was, as well as how different bits of information can produce many different kinds of problems depending on the questions you ask.  They’re not quite ready to think this way yet, but I gave them a challenging warm-up on Tuesday asking them to think about the questions they could ask (oh, and thanks for not commenting on the ages mentioned in this problem–thankfully no one said anything about how OLD Mrs. Bearden is!!).

CAM01521Friday

You’ll notice that this one doesn’t have any post-its on it.  I was actually home with a sick little girl on Friday, but snapped a picture as I put it up to leave for the sub to talk through with my friends.  This one was based on both our 2-digit addition work and a conversation we were having the other day about how many 1st graders there are.  How would you solve it?  What model would you use to record your thinking?

First Grade Math Warm-Ups: Week of January 26-30, 2015

This week was CRAZY busy, so only 4 warm-ups–you know how you have those weeks where NOTHING happens and those where EVERYTHING happens at once?  This was one of the latter.  🙂

Monday

This past weekend, so many people checked out our blog, and it got me thinking about how I could use the scenario in our warm-ups.  The numbers were bigger than in the problem, but I knew I could tweak them to get my kids working with adding 2-digit numbers.  The idea of adding 3 of them is beyond the benchmark for what they’re asked to do this quarter, but I was pretty sure most of them could do it anyway (and it would be a motivating challenge for those that weren’t quite there yet!).  Most of them quickly saw the way they could break the numbers apart by place value and combine those parts back together to find the answer.

CAM01463Tuesday

This warm-up is related to the day before, and planned so that kids might see the ability to use the counting on strategy to solve it.  We’ve been practicing counting on by 10s, and many used that idea to help get to the solution of 219.  We recently started looking at the pattern of how the numbers work when you go past 100, so this one asks them to do that.

CAM01462Wednesday

Happy 100th Day!  This one probably explains itself….

CAM01423Friday

We actually didn’t get to talk about the warm-up from Wednesday until the next day because our 100th Day Blog Challenge kept us so busy!  So Thursday had no new warm-up, but here’s the problem from Friday morning.   The numbers are easier than the ones from earlier in the week, but the focus with this one was to get kids to think about HOW they were showing their thinking so others could understand.

CAM01465Happy problem solving!  Please let us know how it goes if you try some of these in your class! 🙂

100th Day Questions

I have returned to 1st grade this year after about 10 years with 4th-5th graders.  Many things have been the same since my return, and of course there are some things I’ve had to readjust to, or that are entirely new, as is the nature of education.  One thing, though, that was definitely not a “thing” the last time I was in primary is the 100th Day of School.  No, I said that wrong–we definitely HAD the 100th day of school, we just didn’t officially celebrate the 100th day as a holiday.  This is new to me, and as I am coming up on that day (it’s next Wednesday, the 28th), I’ve been thinking A LOT about what I will do with that day in my classroom.  (Before I go on, I feel like should ask that you presume positive intent in my questions here–my focus is on really understanding the why, not judging what others may choose (or not choose) to do in their own classrooms on any given day.  I want to learn here!) 🙂

It seems that other people are also thinking about it, and having similar questions to me.  I found a blog post by Aviva Dunsiger (@avivaloca) the other day, after she posted this tweet:

I found myself nodding as I read her post, as she was asking the same thing I have been struggling with:  Why do we “celebrate” the 100th day of school?  What is the purpose and how can we use this day to continue to help our kiddos think and grow and problem solve?  Why is this day any different than every other day? I’ve read many opinions about how it’s a rite of passage and a fun day to celebrate the milestone of getting so far into the year together, and I’ve heard others say it’s about helping students understand the “bigness” and importance of the number 100.  Believe me, I’m all for having a great day, and I LOVE the idea of kids understanding numbers and being flexible in their use of them.  So the part I’m grappling with is how I can “do” the 100th day in a way that is still high quality and rigorous, while fun and enjoyable–and not just full of things that are “cute” or that we’re doing “just because” they have to do with the number 100 (and let’s be honest–this is really our goal for every day, isn’t it?).

After thinking about this for a couple of weeks, as well as reading about what others are doing, I think I’ve settled on a few things.  Most of them are incorporated into our normal routine, but are focused on the idea (that Aviva mentioned in her post) of the learning we’ve done in the last 100 days.  I plan on there being a focus on how long those 100 days have been and how much learning we’ve already done!  I hope to highlight the “grittiness” we’ve displayed and the fun we’ve had together and how much more fun we’ll have in the rest of the school year.   Here’s what I’m thinking:

1. 100 Book Reading Challenge–with my “big” kids, we have done a 40 Book Challenge the last few years, after reading about it in The Book Whisperer by Donalyn Miller.  I would love to give my firsties a similar, one-day challenge for our class together to read 100 books.  It averages out to 5 books a piece or so, which is TOTALLY doable, and would be a great motivation to reach a goal and work on being better readers.  That’s how it happens, right?  By reading!  I figure we’ll make a chart or list somewhere in the room so we can record the titles as we go.

2. 100 Word writing challenge–I’m not entirely sure how to frame this one, maybe around writing word wall words correctly or creating words from them (like word families), or if we’ll write stories that include 100 words or what…..somehow we’ll write.  Like we do everyday. 🙂

3. What Have We Learned in the Last 100 Days?–Taking inspiration from Aviva’s post, I thought it would be great to document all of the things we’ve learned and done in the last 100 days (which I am sure is WAY more than just a 100) with pictures and words.  Since I’m a regular blogger, I am also a regular picture-taker.  That means I probably have at least one picture from each of our 100 days together.  I’m thinking about having kiddos reflect on each day (probably in pairs) and writing something to go along with each picture.  These could be put into a book (either paper or digital) and we could add to it as we finish up the year.  Again, what a great way to visually see all of the many things they know now that they didn’t know on our 1st Day together!

4. Legos? Blocks? Maker Space?–We are definitely builders in Rm. 202, and incorporate this kind of representation into many things we do on a regular basis.  I have seen ideas for “what would you do with 100 Legos?” which could be interesting, as they could answer the question about what they’ve learned or what they are most proud of.  We did something similar when we returned from Winter Break where they created and then wrote about their favorite thing/event/present from Christmas.  I’d love to give them the same question and have them build something with big blocks or just “stuff” and then have them video their thinking as they explain what they made and why.  The video part would be pretty basic, as we’re just getting into documenting our learning digitally.  Those videos would be great to share on our blogs–which we’re going live with this week, too!

5. 100s game in Math–this will be an easy extension of what we’re already doing!  The unit we’re currently working on is about kids become flexible and efficient with adding numbers within 100.  We’re already playing games, solving problems and having great conversations about place value with bigger numbers.

6. Read Aloud–I know that Read Aloud has been a focus around here lately, so maybe we’ll read 100 pages in our book on Wednesday, too, as a way to celebrate a great story together!

I guess we’ll see what I end up going with (as it will happen in just 3 days from now!).  I’d love to hear your thoughts on how YOU will be spending the 100th Day of School.  What questions did you consider in your planning?  Please come back later this week to see the update on what actually happened in Rm. 202, and/or follow us @jbeardensclass to enjoy the day along with us!

Have a great week! 🙂

First Grade Math Warm-Ups: Week of January 20-23, 2015

Another short week of warm-ups because of MLK, Jr. Day on Monday, but the ones we had this week are goodies!  Read on and happy calculating!  Please let me know how/if you use these in your classroom!  Feel free to add your own warm-ups in the comments, too! 🙂

Tuesday

CAM01397The unit we’re in right now is math is focusing on adding numbers within 100, and on using place value to do so in an efficient manner. My focus then, this week has been on how to create opportunities to think about tens in a meaningful way determine which strategies and models make sense in each situation.  This one was just a great place to start our conversation for the week because it has so many answers.

Wednesday

CAM01396

We’ve been doing many problems around scenarios, and I wanted to see what they could do with straight numbers–especially related to place value.  This was a great one to see what they know both about tens/ones, and what they know how to do with them.  You can see that there are already many known strategies and models floating around that we can build from as we go forward.  YAY!

Thursday

CAM01395We’ve been playing the 100s Game this week as we practice counting to 100 by different numbers.  We’ve had lots of practice with counting to 100 by 5s and then 10s (really fast!), but then we practiced counting by 10s and NOT starting at 0.  We used a deck of cards to decide what was our first number, then we went around and stopped at the number that was closest to 100 (for example, if we started with 6, then we’d say 6, 16, 26, 36, 46, 56, 66, 76, 86, 96).  This warm up was similar to the game we’d been playing, only I wanted to see if they knew what to do when they went over 100, so asked them to go as high as they could.  HA!  Man…were those numbers high!  One friend went all the way to 867 (and I think he only stopped because he ran out of time!), and many went to the 600s or so.  As we discussed the problem and did it together, I quickly found out that they did indeed know the pattern of how it works when you get into the 100s.  This will be so handy as we keep going, and many will modify their counting on strategy from numbers within 20 to counting on by 10s with numbers within 100.

Friday

CAM01393This one was a true story about how I spent my evening last night!  While it is really a problem to see what they can do with tens, it’s also the beginning of multiplicative thinking, as it’s also 8 X 20 or 20 X 8; either way, i want them to recognize that it’s 8 groups of 20, not 8 PLUS 20.  Most did a SUPER job of this and had great thinking about how to figure it out.  Several connected the 20 to counting by 2s, and some saw the 2 10s inside 20 and counted by 10s to get to 160.  The best part was that NO ONE sat and did nothing.  Everyone tried a strategy, and were willing even if they weren’t quite sure about the answer.  I LOVE how gritty these kiddos are!

Our record of how to use 2s to figure out the answer.  We made sure to highlight how those 2s can mean 2 10s and so 16 10s is 160.  Then, just for fun, we figured out how many hours those minutes would be equal to: 2 hours and 40 minutes!

First Grade Math Warm-Ups: Week of January 12-15, 2015

This week we only ended up with 2 warm-ups because it’s all we had time to talk about!  Enjoy! I’d love to hear how you’re using them in your classroom, or with your kiddos at home!

Monday

Please ignore the fact that my green markers are never juicy and always make our charts look old. 🙂  Thanks to the fact that my Master’s program is now over, I have at least a little bit of free time, and for me that means baking!  Here’s a grouping problem with 10s that’s about some cinnamon honey wheat crackers I made for my kiddos!

CAM01337-1Wednesday

Again, all the best math scenarios come from real life, right?  This problem is a less-than-true story about my CRAZY drive home on Tuesday evening!  The actual time in the car (because of SIX ACCIDENTS on the highway between school and my house, as well as forgetting a pile of papers I needed on my table at school and having to drive all. the. way. back. to. school. again.) was MUCH longer.  My littles just weren’t ready for numbers that big yet.  Maybe next quarter. 🙂

CAM01338-1Happy calculating!  Hope you’re having a great week!  Stay tuned for this week’s warm-ups soon! 🙂

First Grade Math Warm-Ups: Week of January 5-9, 2015

Welcome back to school!  I don’t know what the weather is like where you are (well unless you’re where I am!), but here it has hardly gotten out of the teens and my bones are chilled!  It was nice to be able to be warm and cozy in Rm. 202 with my first grade buddies this week!  Here’s what we studied:

Monday

Again, true story from my life used for our warm-ups.  It really makes them interested in solving the problem when they care about the context!

IMG_4093

Tuesday

This week we’ve been continuing to work on knowing if we should add or subtract.  When we discuss the problems, the question I ask them is not “What answer did you get?” but instead they turn to their partner to tell them what operation they used how they knew what to do.  I am listening for explanations related to the context and what is actually happening, rather than specific clue words.  Just knowing clue words (like “left,” “in all,” or “how much more”) doesn’t always work; depending on how they are used in a problem, they can sometimes mean addition or subtraction.  Or, you can add TO subtract (as in the strategy of counting up), so it becomes even more confusing.

Wednesday

Thursday

This problem is an addition problem, but also gets kiddos thinking about multiplication without really knowing it.  They have to really be thinking about the situation–I bought 2 bundles that each cost $20–or they will use the 2 and 20 and just add or subtract them.  It was great to see how many kiddos understood the way the problem worked.

IMG_4096

Friday

The focus with the numbers in this problem was to help mathematicians use known combinations to efficiently figure out unknowns.  Ideally they would see make 5s to make 10 or see a 6 and a 4 to also equal 10.  This idea of grouping connects to our future (well, really continuing) study of place value and addition numbers within 100.

First GradeMath Warm-Ups: Week of 12-15 to 12-19

Monday

I participated in the St. Louis Hot Chocolate 5K with my family on Dec. 14 and of course I had to use it as a context for a problem of the day!  And yes, it is a true story.  I’m really slow. 😦

CAM01255

Tuesday

We’ve been working on addition strategies, so the numbers in this one were chosen so that hopefully kids would see the 10 and use it: 6+4 =10 and then 10+7= 17.

CAM01256

Wednesday

One thing I want my mathematicians to be able to do is think flexibly about numbers.  Sometimes I give the the answer and ask them why it reasonable (or not!).

CAM01257

Thursday

I’m not sure why I wrote the word tonight on this problem (as it doesn’t make any sense since I wrote it the next morning!), but you get the idea. 🙂  The focus was both on adding a string of numbers, as well as determining whether to add or subtract.  We’re getting really good at knowing when to add and when to take away, by thinking about the context and picturing the situation.

CAM01258

Friday didn’t have a math warm-up since we didn’t have math.  We had a delightful Winter Party instead!  Hope you had a great holiday break, math friends, and that you’re back into a positive January groove! 🙂

First Grade Math Warm-Ups: Week of 12-8 to 12-12

So excited how these are working out, and how they lead to such great conversations during our math time.  So easy to get math brains thinking early in the day and then letting it simmer all day.  By the time we come back to it at 2:00 it somehow makes even more sense.  LOVE!

Monday

CAM01132

We’ve been working on doubles a lot lately, during conversations, in groups and by playing games.  The hope is that my mathematicians can then transfer that knowledge to solving problems.  This one let them give it a try.  And since you’re here, let me show you the doubles games we’ve been playing–I think we might have to make a new version of these for every season:
