Late last week I put these together. They’re working on a lot of the same skills (mentally adding 10s and multiples of 10s, 100s, expanded form and standard form) but a new one that we needed additional practice on that I hadn’t anticipated is comparing and ordering numbers.
The set includes both two-digit and three-digit numbers. This allows you to differentiate for your students. Depending on how strategically you set this up, you can even have students practice working with negative numbers.
Some of the subtraction rules involve subtracting 10, 20, 30, or 40. If students work with a lowered value number, they will end in the negatives. This rocked the socks off of some of my high kids. Of course that one that got it all without any of my help made me epically proud (and a little sad I wasn’t able to challenge him like I thought I would.)
For many of the centers, these numbered football cards are used. I kept things black and white (other than optional mats) to keep costs down. And, since my colored printer at work never works, it kept me from printing them all at home.
There’s also a set of numbers in helmets. These are used to match standard form and expanded form. However, I plan on using these same ones next week as we are continuing to practice addition and subtraction with regrouping.
