Clear the Board (Example)
Clear the Board is a fun race you won’t want to miss. Players start with a 100 block and roll the die to determine how much will be subtracted each round. Careful! Make sure to “trade” your blocks correctly, or you won’t finish the race. After 5 rounds, the person with the lowest score that was closest to “clearing their board” wins.
Subtracting Larger Numbers
Base 10 blocks make it easy to understand place value. Previously, students used base 10 blocks to add numbers up to 9999. The same concepts will now be applied to help students subtract larger numbers.
