### 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?
