Patterns in Decimal Division

MCC5.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.

Essential Question: How can we use basic facts and patterns to divide with and without decimals?

If I know that ÷ 5 = 40 & 20 ÷ 5 = 4 Then, what would be the answer to – 2 ÷ 5 = ** You know the answer will be a decimal because divisor is less than the dividend***

If I know that ÷ 8 = 50 & 40 ÷ 8 = 5 Then, what would be the answer to – 4 ÷ 8 = ** You know the answer will be a decimal because divisor is less than the dividend***

If I know that ÷ 6 = 30 & 18 ÷ 6 = 3 Then, what would be the answer to – 1.8 ÷ 6 = ** You know the answer will be a decimal because divisor is less than the dividend***

100 ÷ 5 = _____ 10 ÷ 5 = _____ 1 ÷ 5 = _____

300 ÷ 5 = _____ 30 ÷ 5 = _____ 3 ÷ 5 = _____

160 ÷ 4 = _____ 16 ÷ 4 = _____ 1.6 ÷ 4 = _____

630 ÷ 9 = _____ 63 ÷ 9 = _____ 6.3 ÷ 9 = _____

720 ÷ 8 = _____ 72 ÷ 8 = _____ 7.2 ÷ 8 = _____
