Our math warm-ups are almost always related to what we’re working on in math. Sometimes it’s the beginning of the unit, and so kiddos don’t have much schema yet and aren’t really sure what to do. Later then, the warm-ups become practice of the strategies they’ve learned and are working on perfecting (or at least using more efficiently). This week, they were even the same topic: Walker’s Club.

Let me explain…

In a nutshell, this year we started a program to help our Robinson kids stay healthy and active, as well as have productive fun at recess. We call it Walker’s Club, and on Tuesdays and Thursdays, everyone walks laps around our playground at recess. Every kiddo (and now even teachers!) has a card to keep track of laps that is punched each time they come around. Parents, principals, teachers and even a group of kids volunteers to be punchers, and there’s always a big buzz about how many laps kiddos have at any given time. There are prizes called Toe Tokens that kiddos earn at certain increments along the way. So fun!

This picture seems like it’s from so long ago! Don’t know how I didn’t share it earlier–they seem so little, don’t they?? 🙂

Well, to make it even better, and to celebrate National Walkers’ Day (which happened on April 1), Mrs. Wilson decided to make a competition for the month of April to see who can walk the most laps. Each grade level will have a winner, and that class will earn an extra 20 minute recess + POPSICLES!! Needless to say, it. was. on.

Math this week, then, naturally began to revolve around Walker’s Club laps: setting goals (first it was a conversation on how to set goals) how many laps other classes were walking, how many we could walk in a day, and how many we actually walked in one day. Oh, and strategies for how to add up long strings of numbers so we could answer each of those previous questions.

Check out what we’ve been working on this week!

As we started out our goal-setting, we decided (ok, so I suggested) that we should figure out how many we laps we usually walk on a Walker’s Club day. We could use this number (along with some other data we collected) to set a goal for how much each kiddo would walk/run every WC day.

After we knew how many laps was our usual, we decided to ask our first grade friends the same question. Since they were the ones we’d be competing against, we also needed to know their usual number so we could adjust ours and make a goal that would matter. This one’s from Ms. Turken’s class. We got some data back from other classes, too, but haven’t yet analyzed it.

I need to insert a little note here: the first time we sat down together to add up that big string of numbers, we didn’t really know what to do.

See this? These are all of the answers we got when we went to work with our partners to add up the data. WOW! All the way from 10 to 122! We needed some practice with an efficient and ACCURATE way to put lots of numbers together. This gave me some ideas for future work in warm-ups.

So next came the idea of finding 10s as a quick (and organized) way to put lots of numbers together. We then added (and readded) all of our data together from our chart and Ms. Turken’s chart. We also tried it with other random lists throughout the week (so that when we came up on Walker’s Club data again, we’d be better at using that 10s strategy):

This one was a practice problem from the morning, but we didn’t quite get time to review it later in the day.

This one was actually the warm-up from Friday (when I was out of the classroom), and I showed the sub how to record the combinations of 10s.

This practice did help us, and when we added together our first OFFICIAL Walker’s Club list of laps, we knew what to do. The problem (which was a good one to have) was that our list included lots of numbers that we couldn’t put together to make 10s. That’s totally cool, though, because Evan had just been working on how to put numbers together to make 20s and 30s (and other multiples of 10) on Dreambox, so he helped us figure out what to do with all of those 8s:

When I wrote my lap number up there, I felt a little bit funny since it was so much less than my Rm. 202 friends. I was SUPER glad to know it helped us out, though, as we could use it to go with some other numbers to make a combination of 20. Whew!

Check that out: on our first day we walked (and ran) 114 laps!! This made us feel like we were off to a tremendous start (especially since we knew Ms. Turken’s class had only done 75 on their first day) and helped us set at least a preliminary goal for ourselves: we need to walk/run at least the number we did today to stay ahead of our friends. We’ll talk more about how many that will be in all when we come back next week, and we’ll adjust that goal as we go forward and begin to hear what the other 3 classes are doing. And hey, no matter who wins this April competition, we ALL WIN because we’ve got new strategies in our toolbox! Plus we will all have had lots of fun and lots of fresh air and exercise! How can anyone complain about that!?

We’ll keep you updated on our progress as we go through the month! 🙂
