Patterns of Zeros and Decimals when Multiplying and Dividing

• This Patterns of Zeros and Decimals when Multiplying and Dividing resource is a twenty four question practice sheet for the 5th grade math Common Core Standard

The first 8 questions are multiplication, the second 8 questions are division, and the final 8 questions are a mixture of multiplication and division. The problems contain both whole numbers and decimal numbers and use the powers of 10: 10, 100, 1000, and 10,000.

Students should not use a calculator but use what they have learned about the patterns of zeros and the placement of a decimal point when multiplying and dividing by powers of 10. The sheet should be used after the skill is taught and is a way for the concept to be reinforced. An answer key is included.

Since the students will complete the problems mentally, all 24 products and quotients are contained on one page with a one page answer key. The file is a PDF. Example problems are 34 x 100 and 596.2 divided by 1000.

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.
