Teaching Exponents. We have been busy in math working on exponents! I have an accelerated 5th grade group, so we needed to cover 5th and 6th grade standards on exponents. We haven't quite gotten to evaluating expressions with them yet, but they are exponent pros now! Here are the two anchor charts we made, and the students also put these into their math journals.
Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the equals sign in (5)(5)(5) = 53. The exponent, being 3 in this example, stands for however many times the value is being multiplied. The thing that's being multiplied, being 5 in this example, is called the base. This process of using exponents is called raising to a power, where the exponent is the power. The expression 53 is pronounced as five, raised to the third power or five to the third.
