Ch. 13 Order of Operations including Exponents

5th Grade Standard

5.OA.A.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

5.NBT.A.2 Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

Here is a good overall explanation of the Order of Operations with some information on why we need to have it.

Intro to exponentsSal shows how exponents are repeated multiplication

This is an introduction to exponents. Students should mainly understand that an exponent means "repeated multiplication", and understand where they fall in the Order of Operations. We will mostly be working with powers of 10 in 5th grade, or to the 2nd power.
