# Lesson 128 of Doodles Do Algebra

We are starting by learning (or reviewing) the concept behind raising a variable to a power. What does “power” mean in mathmatics? A power is a product that comes from multiplying a quantity by itself, a certain number of times. The number of times you multiply the quantity by itself is the index or exponent of the power.

You can explain to your child that all powers are is a simpler way of keeping track of the math of certain big numbers. The first step is for him to learn the new vocabulary and then the math will be easy to do.

Today’s worksheet is a simple matching between the mathmatical expression of six different powers and their corresponding description, written out in english. I also add an extension to get your child thinking about expanding the idea of powers with one problem that involves raising an expression to a power, instead of just raising a quantity to a power.

All in all, this sheet is a fun break from the intensity of the last few lessons. So encourage your child to have fun and be creative (maybe he wants to draw lines of cat footprints to match the terms instead of lines).
