1.4 Calculating Powers
Calculating Powers it the fourth section of Chapter 1: Number Relationships.
Introduction to Powers
First, we defined a power as a numerical expression that shows repeated multiplication. We broke out linking cubes and did a couple examples of different multiplications, squares and cubes using those, to help clarify different aspects of powers.
Activity: Stacking Paper
This activity is meant to help students realize how powers apply to the real world. We have the example of cutting a pile of paper in half and stacking it a total of 20 times. Most students started by actually cutting paper apart and calculating the height of the stack of paper. After a couple cuts, they started to have difficulty doubling the stack.
