Required Resource Materials

Sets of ten connected unilink cubes wrapped in paper

Activity

Using Materials

Students work out 5.2 ÷  4. It is likely that students will give out 1 whole to each share, then convert the 1 whole + 2 tenths that are left over into 12 tenths and share out 3 tenths to each. So 5.2 ÷ 4 = 1.3

Using Materials, Using Imaging, and Using Number Properties

The teacher can select problems from the set below for any stage. When teachers make up their own examples, wholes need to be broken down into tenths, and the answer is to 1 d.p. So 3.2 ÷ 4 = 0.8 is suitable, but 3.4 ÷ 4 = 0.85 is not.

Problems:

5.2 ÷ 2             1.6 ÷4              6 ÷ 4                1.2 ÷ 3

1.2 ÷ 6             7.5 ÷ 5             2.1 ÷ 3             2.1 ÷ 7

14 ÷ 4              3.6 ÷ 6             12 ÷ 8             4.5 ÷ 3

41.2 ÷4            21.6 ÷ 4          22 ÷ 4             19.2÷3
