Base Ten Blocks can be used to show a number. A basic place value activity using Base Ten Blocks is to write a number and represent it using various blocks. This activity can be expanded into adding or subtracting numbers to highlight carrying or borrowing.
A popular game amongst younger students is Race For A Flat. Players take turns rolling number cubes and collecting the sum of the cubes in Base Ten Blocks. A player regroups (or trades) her Base Ten Blocks when she has collected more than ten of the smaller manipulative. The goal of the game is to earn a flat, worth 100 units, by regrouping smaller units. For students proficient in addition, start with a flat and subtract the sum of the number cubes for an activity that highlights borrowing. For older students, this game can be played using multiplication, with the goal of earning a cube, worth 1,000 units. In this variation, each student multiplies the numbers rolled and then adds the units she has earned, regrouping as necessary.Learn more about K-12
