Multiplying


Idea: We can use Base 10 Blocks in a grid to help us multiply numbers

Reflection 1: Blocks take the place of numbers in the grid, but we need to break down the number into par to make it easier to work with them. For example, 26 X 16. Instead of 26, separate it into 2 tens and 6 ones and instead of 16, separate into 1 ten and 6 ones.The block on the outside, frame the products we are creating inside. Eventually there will be more blocks than what we started with.

Reflection 2: When we multiply, we always get more.
