## Scenarios

### Scenario 1

• At the car factory they need 4 wheels to make each car. How many cars can they make with 72 wheels?

• Stephanie said:

• Nine 8’s are 72.

• So we double the 9 to get 18.

• What stage is Stephanie at?

### Scenario 2

• You have 37 lollies and you eat 9 of them.

• How many lollies do you have left?

• Arita says:

• The answer is 28 because four 9’s is 36, and 1 is 37. So the answer is three 9’s and 1, or 28.

• What stage is this?

### Scenario 3

• There are 6 baskets. There are 24 muffins in each basket. How many muffins are there altogether?

• Tim says:

• It’s six 25’s and you take away 6.

• What stage is this?

### Scenario 4

• In a box of 240 tomatoes there are 65% that are ripe. How many tomatoes are ripe?

• Tom says:

• Well 50% is 120, and 25% is 60,

• and 12.5% is 30.

• So it must be close to 150.

• What stage is this?

### Scenario 5

• What is of 28?

• Steve says:

• I get 21 because half of 28 is 14 and half of 14 is 7. Then 7+7+7 = 21

• What stage is this?
