# Math Warm Ups: Week of Oct. 19-21, 2016

I used to blog our math warm-ups every week.  Then this year I changed our warm-up plan again and sometimes they are questions other than math problems and so I never really got into that routine.  This week, however, they were indeed all math warm-ups so I thought I’d share what we’ve been doing!

(This was a short week of school, with only 3 days and 2 warm-ups.  Small but mighty math thinking!)

My kindergartener, Allie, created this one for Rm. 2o2 kiddos and was very excited to share it with them.  I was impressed with how they are getting better at telling stories and creating word problems to solve.

Some highlights of the answers to this one:

We also tried one during math on Friday as an extension after we’d talked about the warm-up together.  We’re learning how to use Padlet, so it’s been the place we’ve been sharing our thinking lately (and since we’re still working on the logistics, some friends didn’t quite get their answer on the board).

Great thinking lately, Rm. 202 friends!  More to come soon!

# Morning (Mostly Math) Warm-Ups: First Grade 2016

If you have been around 20somethingkids for more than this year, you’ve probably seen my math warm-up posts, and then the start of our writing warm-ups that went really well in 2nd grade last year.

This year I started morning warm-ups pretty soon after school began, to get kiddos into the habit of reading the easel, thinking about their answer, and adding their post-it.  The ones in the beginning, though, were not yet math (or writing), but were other things instead that were related to what was going on in the classroom.

Our first warm ups of 2016 looked like this:

Then, once we had the hang of it, we started into more traditional math warm-ups, which are related to what we will be talking about that day (or what we did the day before):

Kiddos are on a roll with this Rm. 202 routine!

# #FDOFG: …and 123s

We worked on letters letters this week, and also got some math into the mix, too!

One way was with one of our first morning math warm-ups (which I will start to share about later).  I asked a short, simple question with infinite answers, allowing every kiddo to share their initial thinking about what math would be this year.

The variety of answers was great, with no one having to use the prompt I taught them of “I don’t know yet, but here’s what I’m thinking now…”  I love that someone’s answer was “math is fun!”  Many kiddos said “numbers” and many others gave examples of kinds of math like adding/subtracting or wrote equations.  I was impressed that they were not scared by this question, even though we were only on day 9 of 1st grade!

After we discussed this warm-up, I gave everyone an activity that would allow them to show me (and the class) a little bit about themselves as people and themselves as mathematicians.  Now…it is a very infrequent thing for me to ask everyone to do the very same thing at the very same time in the very same way.  But since it is early in the year, and we 1) don’t have our iPads yet (which is how we often differentiate opportunities), and 2) it’s still early in the year and we don’t have all of our routines established yet, this seemed like a time and place to ask the whole class to try something together.

The general idea was based on a math poster that was shared in our school’s Sharetank on Facebook by Mrs. Hill ((a 5th grade teacher):

Ms. Turken made the template we used in 1st grade, and it was most of the same questions as this 5th grade version, but you’ll see that our equations were a little different. 🙂

After kiddos were finished with their Math About Me posters, I put them in pairs for them to have their first go at a math game.  We had not had a chance to prep for this, but since it didn’t include a die or an iPad, I was pretty sure they could handle it without much instruction.  Once I explained how to play Turn Over Ten, they got busy and did a pretty great job of quietly playing while the rest of us finished.

Now for whatlearned…

*The idea of using numbers to tell about yourself is a GREAT idea, but I should have done it in a different way.  This was a bit formulaic for 1st graders, had a lot of directions, and they needed a lot more help than I had first anticipated.

*Most kiddos had the same answers for the number, and made the equations in a similar way, too, although they did vary a little in the order their labels and cards went on the paper.

*This was DEFINITELY more of a lesson in following directions than a community building or math task.  We didn’t even have a chance to share our answers when we were finished.

*I did not clearly explain why we were doing this, which made it much less meaningful to my students, and therefore probably was not the best use of our time.

*My class works really well when they are busy with an individual, partner or small group task, and can do a lot of things independently already, even at this point of the year.

*Most kiddos are willing and able to talk to each other to clarify directions, ask for help and encourage each other when they don’t know what to do.

*They were able to transition very easily from a project to a game.  They followed the directions, worked quietly and were focused on doing the right thing with their partner!

*We have a pretty strong foundation on which to build the rest of our mathematical thinking this year, and kiddos are excited to get started on “real” stuff!

And just like them, I am also excited to get into the “real stuff,” too!  Let’s go Rm. 202 mathematicians!

# Second Grade Math Warm-Ups: Week of May 9-13, 2016

This week was relatively normal, but somehow I only have 3 warm-ups to share.Enjoy! Please comment when you’re finished reading and let us know what you think!

Monday

Yep, we’re still working on subtraction around here.  It’s kind of an all-the-time thing because as soon as you abandon it for longer than a few days everyone forgets how to do it!  This time I gave them the answer and the strategy and had them analyze it for me.  We had a great conversation about why this problem was most efficiently solved by making an easier problem (rather than say, the traditional algorithm or splitting and using a number line to model it) because the second number was close to a hundred.  This made it SUPER easy to subtract in just two easy steps.

Friday

Um, yeah…not really sure what happened that our warm-ups are just from Monday and Friday.  We must have been really busy this week.  Hope I remember what we did so I can tell you about it here. LOL

Friday we actually had a bonus math warm-up because our Writing Warm-Up led us to figuring out some math and making a graph.  And yes, I ran out of paper.  We improvised. 🙂

We are also still working on multiplication, including writing an equation and drawing a model.  This one was cool, because as often happens, kiddos thought of a model that I hadn’t: showing the repeated addition on a number line.  This was a great conversation about which number meant what in the problem (the number of groups vs. the number in the group), and we also talked about how you could flip the problem around and have the same answer.

# Second Grade Math Warm-Ups: Week of May 2-6, 2016

I am a little bit late–sorry!  I forgot a few important pictures that I needed in order to properly share.  Hopefully you’ll still read (and learn with us!).  🙂

Monday

There’s not a lot to explain behind this one except that I wanted to continue to focus on the idea of a fraction being EQUAL pieces, not just the number of pieces in the denominator.  As you can see in many of the post-its, most kiddos understand this when they partition the cookie cake for 4 people.

Tuesday

As I mentioned with a problem or two last week, kiddos are to have a basic foundation of groups and arrays to help them with further multiplication concepts in 3rd grade.  We played a game called Circles and Stars last week, which is basically where they roll a dice twice, once drawing circles and then filling each with the 2nd number’s worth of stars.  Then they figure out an equation to go with the model as well as how many stars there are altogether.  I wanted to build on this idea and see what they’d do with a new problem.  As is seen on their answers, they almost all drew circles with stars (or dots).  I wanted to help them see the same idea as an array, as well, so I connected the equation to brownies (so they pan/array would make more sense).

Wednesday

Now it reads: If I had a rectangular pan of brownies that had 7 columns of brownies on the long side of the pan, and 5 rows of brownies on the other, how many would I have in the whole pan?  Draw a picture.   Great work on the writing and the math, Rm. 202 friends!

Thursday

Friday

We’re still working on many concepts all at once, and solidifying our understanding of them.  Love my little speech bubble?  We always talk about how the numbers in the problem scream at us to tell us which strategy is most efficient for them, so it just seemed fitting. 😀

# Second Grade Math Warm-Ups: Week of April 25-29, 2016

We have been on a roll with warm-ups lately, and maybe since we’re still talking about many different things, they’ve given us a way to keep all the balls in the air.  Love that.  Enjoy! 🙂

Monday

One of the topics we’re working on right now is the foundation of fractions, and understanding about equal parts.  This warm-up led to a GREAT conversation about how 1/5 is always a 1/5, but the actual portion that is being considered changes based on the whole.  Oh, and we were all hungry when we were finished. 🙂

Tuesday

It seems like addition and subtraction is a never-ending concept with 2nd graders, and we’re still working on it.  Oh well, as long as it takes.  School year’s not over yet and they can get it! Here was another opportunity to practice.

Wednesday

Ok, so I need to explain that that picture is a pizza, not a target.  It’s based on a picture we had looked at the day before in a math conversation.  It was based on an 8-slice pizza and how we could share it fairly if twice as many people showed up for our party.  This was the way one group suggested we do it, and we had to discuss whether we agreed if it was fair.  Which piece would you want? 🙂

Thursday

We had a FABULOUS walking field trip on Thursday at the time we normally do math warm-ups, so didn’t have one that day.  We had a great day in the park and a movie instead! 🙂 (Don’t worry–it was connected to our curriculum!)

Friday

Another topic (which I found a way to weave into this conversation, too!) is the foundation of multiplication.  We told many stories of groups of things with this one.  Great thinking, Rm. 202 kiddos!

# Second Grade Math Warm-Ups: Week of April 18-21, 2016

This was a 4-day week at school, but since we’ve moved our MWU to the afternoon (instead of first thing in the morning), it has seemed it’s been easier to make them happen every day.  Maybe it’s just because of the unit we’re in, too, but our conversations about them have been SUPER POWERFUL lately.  Can’t imagine teaching without this part of our day!

Monday

I definitely should have taken a before and after picture of this one.  The circles were all filled up with post-its when we sat down to talk, but we had to work through them and decide which ones sounded like things mathematicians would say about these polygons.  Many of them were vague or didn’t use mathematical terms.  They said things like “they’re different” or “they’re the same.”  We talked through the definition of polygon (hence the words over there) as well as what some mathematical terms were that we should listen for as we narrowed down the choices.  This idea of comparing is something that students are expected to know how to do independently with two different polygons by the end of the unit, so trying some together along the way was crucial.

Tuesday

This one matches up with both some work on shapes we had done earlier (names and attributes), as well as a replay of the question from the day before to see how they’d do in the same situation with different shapes.  The number of specific, mathematical responses was much greater this time and we had less work to do to make our Venn Diagram make sense.

Wednesday

This question has a great story to tell (which is SO long and involved I’ll be nice and put it in a different post!), and really gave us lots of math to chew on.  And I thought I would be an easy one.  Those are always the problems that surprise me.

Do you see the marks on the word HALF up there? Here’s a close-up:

We’re applying our knowledge of lines, angles and polygons everywhere we look!  This wasn’t even part of the question, but of course was a great part of the discussion!

Thursday

After all our hard work (which I hope you’ll pop over and read about), I wanted to see if they could remember and apply it to a similar but new situation.  Most could see how the knowledge we had gained the day before about halves applied to thirds (and therefore to fourths, fifths, sixths, etc.).

What did you work on as a mathematician this week?  What warm-ups would you suggest to us that include angles, polygons or fractions?  We’d love to try some more! 🙂
