Arithmetic Grade Four

Lesson Seventeen: Division Review


One way of rewording a division question is like this:

  63 / 9 =

  How many sets of 9 are there in 63?

Here's another example:
  40 / 8 = 

  How many sets of 8 are there in 40?

The next set of practice problems uses this form.

To solve these problems we can draw pictures or use the subtraction method shown in the previous lesson. Here's another example with pictures and subtraction for the problem 21 divided by 7.

     21
     -7
    ----

     -7
