Dividing Decimals NBT.7
3
Learning Targets I can explain how to divide a decimal by a whole number. I can explain how to divide a whole number by a decimal. What goals can we establish through our targets? How can we monitor our progress?
4
Our Goals
5
Let’s Review our Vocabulary!
Divisor Quotient Dividend With your partner, formulate an equation. Label the parts with the given vocabulary words. Be prepared to share!
6
Let’s Review… animation.html Explain the process for dividing decimals by a whole number. What happens to the decimal? You Try to Warm-Up: Divide 98.4 ÷ 8
7
Standard Algorithm: You Try a Few On Your Own
1.) Divide 15.6 ÷ 3 2.) Divide ÷ 7. Share your strategy! Multiply to find the products. 23.46 x 10 23.46 x 100 23.46 x 1,000

Let’s Review How is dividing whole numbers by decimals different from our last strategy? What previous skill helps you to divide? Can you restate/rephrase the sentences in the box? Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's. Step One: Let’s multiply 0.2 x 10 in order to slide the decimal to the right. 0.2 x 10 = 2 Step Two: Whatever we do to the divisor we MUST also do to the dividend. 15 x 10 = 150 Step Three: 15 ÷ 0.2 has become ten times larger. We now have 150 ÷ 2. 150 ÷ 2 = 75 THEREFORE 15 ÷ 0.2 = 75
