Explain that with partial quotients division you break up the problem into steps and solve it in this way. You write down the problem and draw a line underneath it. Next you can make a helping row of the table of the number that you are dividing by. You don't have to include every problem in this row. For example, you can always double or halve the problems. After that you solve the problem step by step and see how many times 3 fits in 66. After every step you write down how much you have left over. If you do not have any more left over, then you have finished. You then add up all of the numbers that tell how many times 3 fits in 66 (10, 10, and 2). Have the students solve more problems using partial products. Have them write down the problems on graphing paper, and also write down the table of the divisor if they need to. Next you explain that you can also solve a problem with larger numbers in the same way. The students also practice this kind of problem. Ask various students what steps they took to solve the problems. Encourage the students to take as large steps as they can.
Check whether the students can divide using partial products by asking the following questions:
- Why is it useful to be able to divide using partial products?
- What aid can you use when dividing using partial products?
- Solve this problem using partial products division: 72 ÷ 12
