Jenga math! Write the numbers one (0_1) to one hundred eight (10_8) on the blocks using both sides. Write a line under numbers that could be read upside down (0,1,6,8,9) when they are both numbers on a side. Leave the signs off! Pull out a block to solve a problem: Addition, subtraction, etc. Pull two for double digit addition, subtraction, multiplication (or one block using both sides). You can also use the blocks for comparing and ordering! Use a recording sheet for accountability.
