This Estimate, Roll and Race to 100 activity is a great activity to try with your learners for your 100th Day of School! It’s simple, NO PREP, and tells you so much about your learners’ understanding of how numbers work!

Estimate, Roll and Race to 100
To do this activity, I recommend printing two of them front to back. For example, you could print the 1-die 100 board on the front and the 2-dice 100 board on the back of one page. If you want to make it reusable, slip it into a plastic sleeve protector. You just have to be sure you have 3-4 different colored dry erase markers for learners to use.
To “play,” learners first estimate how many rolls they think it will take to get to 100 with either 1 die, 2 dice, or 3 dice. They write that number up at the top of their page.
Then, they start rolling and racing.
When they roll a number, they color in that many spaces on the hundreds board. So if they roll a 5, they color in 5 spaces. If they only roll a 1, they just color in one space. They keep rolling and racing until they get to 100. We don’t play that you must have the exact number to finish the board.
Roll and Race to 100 Math Conversations
Although this is game-like and kids like it, I honestly don’t think the “magic” of this activity is necessarily in the activity itself. It’s in the conversations learners have before, in the midst, and at the end of this activity that make it work so well.
Even if you’re implementing it whole group, I still recommend that each learner has a partner so they can discuss their thoughts about questions such as:
- About how many rolls do you think it will take to get to 100 with one die? What would be a reasonable number? Could it take 10 rolls? Why or why not?
- How many times did you actually roll the die? How far off from your estimate was it?
- If you were to do this activity again, how likely do you think it would be that you would roll the exact same number of times again? Why do you think that is?
- So, if it took you ___ many times to roll to 100 with one die, do you think it will take more or less rolls to get to 100 if you use two dice/three? Why do you think that?
I love how this activity mixes probability with logic and numbers to 100. Fun!
