An exponent is just a shortcut for repeated multiplication — 2³ means 2 × 2 × 2. So this lesson runs on solid multiplication facts and knowing how to multiply the same number again and again. Warm those up and powers feel simple.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 To add the same number many times to find a total.
Example: 4 × 3 means add 4 three times: 4 + 4 + 4 = 12.
Level 1 A number you multiply by another number.
Example: In 4 × 3 = 12, the factors are 4 and 3.
Level 1 The answer you get when you multiply.
Example: In 4 × 3 = 12, the product is 12.
Level 1 Groups that each have the same number of things in them.
Example: 3 baskets with 4 apples each are 3 equal groups of 4.
