Using Number Properties

Problem: Complete 13 ÷ 2 =  ? wholes + ? tenths. Predict the decimal point version

of the answer, then check on a calculator. (Answer: 6.5)

When teachers make up their own examples, they should make sure the answers are

to 1 d.p. So 13 ÷  5 = 2.6 is suitable, but 11 ÷÷ 4 = 2.75 is not.

Examples:

Find each answer and write it in two forms, that is, the words in wholes and tenths

and the decimal point shorthand:

21 ÷ 5              22 ÷  4                         10 ÷ 4              13 ÷  2                 15 ÷ 2

13 ÷  5             14 ÷  4                         18 ÷  4             17 ÷  2                 25 ÷  2

26 ÷  5             30 ÷ 4                         2÷ 4                 1÷ 2                15 ÷ 2
