Bricks in Tray
decimals · multiplying decimals by powers of ten
To multiply decimals by a power of ten.
Bricks in Tray is a Grade 5 decimal game for exploring what happens when decimals are multiplied by powers of ten. Players toss two colors of bricks into numbered egg-tray spaces, using one color for digits to the left of the decimal point and the other for digits to the right. The landing positions create decimal numbers that students record and transform, making place-value movement visible through the game setup.
Use it for partner or small-group work when students need to connect powers of ten to place value rather than memorize a “move the decimal” rule. Ask students what changes in the value of each digit and why. Create a free Find a Math Game account to generate teacher-ready lesson support for Bricks in Tray.
