Online practice for grades 5-7

On this page, you can practice with exponents and powers, such as 5^{2} or 10^{6}. Students usually learn about exponents in 5th or 6th grade, but 7th grade students can benefit from practicing them too.

An exponent is the little number in this expression: 2^{4}. It indicates how many times the *base number* (in our case 2) is multiplied by itself. So, 2^{4} means 2 × 2 × 2 × 2 = 16.

You can choose to practice either simple expressions with exponents, or expressions where we multiply a power of ten by some factor, or both.

You can choose timed or untimed practice and the number of practice problems.
