1st-4th Math Coach Constantly Searching for New Ideas

Modified Roll and Build

For those of you unfamiliar with the traditional Roll & Build from Illustrative Mathematics, you can take a look here.

I followed a similar idea, but put it into practice a bit differently. I wanted to work on place value understanding which the original Roll & Build is fantastic for. But, I also wanted to include some simple adding and make it last a bit longer to really drive home the idea that 10 Ones = 1 Ten, and 10 Tens = 1 Hundred. This is 1st grade, so they are expected to compute sums within 100.

The basic format is that a student rolls the dice, and is responsible for finding out the sum. When they figure out the sum, we compare the Ones Blocks for that sum to a Tens Rod.

5 + 4

5 + 4

For example, you can see above that 5 + 4 = 9. We know that 5 + 4 < 10 because there aren’t enough to make 1 Tens Rod. The addition and comparisons make this a really rich activity for students with a seemingly easy premise.

We can see above that we have 8 + 5 = 13. So, 8 + 5 > 10. Again, this activity has a very low floor but it is rich in a number of ways for 1st graders.

 

Then, we start keeping track of what we roll and add up until we get all the way to 100.

Once we get close to 100, the student who rolls to get exactly 100 gets a sticker.

 

The kids were really engaged throughout and noticed a lot about using a place value chart.

  1. Thanks for sharing this! I always enjoy looking at your creative alternative ways for teaching numeracy concepts. I received a very traditional math education myself, and I was lucky that it worked for me. Seeing these new teaching methods, however, shows me that a lot of kids stand to benefit from alternative approaches, particularly students who learn in more spatial, kinesthetic ways. Keep up the good work!
