More Thinking

These problems use similar skills to those used for pages 4–5 and 9 in the students’ book.
Questions 1, 2, and 4 can be solved using either multiplication or a double number line.
For example, for question 1:
4 dresses need 6 metres of cloth.
36 metres of cloth is 6 x 6 metres.
So the number of dresses made is 6 x 4 dresses = 24 dresses.
On a double number line, this would be:

A table is a useful strategy for question 3:

The three tubes of white paint are multiplied by 4 to give 12 tubes of white paint. The other two paint colours also have to be multiplied by 4 to give the number of tubes needed.
