This is a unit designed around multiplying whole numbers which include handouts on :

1. Exponents

2. Mental math

3. Distributive property

4. Estimating

5. Multiplying by 1-digit numbers

6. Multiplying by 2- digit numbers

7. Multiplication properties

8. Value of Decimals *new extra practice*

9. Ordering Decimals *new extra practice*

10. 3 page Quiz *NEW*

Each handout is followed by the same worksheet with answers included.

Other handouts in this unit are review of common core learning standards skills that students need continuous practice on. Many of these handouts include rounding, estimating, decimals, multiplication properties, and each one includes a word problem.

The common core learning standards addressed in this unit are:

5.NBT.1. Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.

5.NBT.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. (Exponents WS, Mental Math WS)

5.NBT.4. Use place value understanding to round decimals to any place.

5.NBT.5. Fluently multiply multi-digit whole numbers using the standard algorithm. (Estimating Products, Distributive Property WS, Multiplying by 1-digit number WS, Multiplying 2- digit numbers )

5.NBT.6. Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. (Multiplication Properties WS)

5.OA.1. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. (Distributive Property)

5.OA.2. Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them.
