Ten-frames aren't just for primary kiddos. Here's a great activity from Van de Walle for working with parts of 100.
Make an easy little I Can card with directions similar to the following:
So, for example, if they roll a 3 and an 6, they can decide to make 36 or 63. Assume they choose 36. They build the number 36 using student ten-frame cards. Each partner mentally calculates the amount needed to make 100 from 36, and then they share strategies. One strategy that might be used is adding 4 to 36 to make 40 and then counting by tens to 100. Another is to skip count forward by 10s from 36 to 96 and then add on the 4 ones. The students share their strategies, check by building 64 with the ten-frame cards, and record their work.
- Take turns with my partner rolling two number cubes
- Make a two-digit number from the digits rolled
- Build the number using ten-frames
- Mentally determine on my own, while my partner does the same, what number will combine with the number we created to make 100
- Share my solution with my partner
- Check my work by making the other part using the ten frames
- Record my work in my Math Journal
Download this sheet, copy it on cardstock, laminate it, and cut the cards apart to make a student kit of small ten-frame cards.
