  1. Identifying Strategy Stages

  2. Stage 0 :- Emergent • The student has no reliable strategy to count an unstructured collection of items.

  3. Question 0 • Show me eight lollies.

  4. Stage 1 :- One to One Counting • The student has a reliable strategy to count an unstructured collection of items.

  5. Stage 2 :- Counting from 1 on Materials • The student’s most reliable strategy is counting from one on materials to solve addition and multiplication problems.

  6. Stage 3 :- Counting from One by Imaging • The student’s most reliable strategy is counting from one without the use of materials to solve addition and multiplication problems.

  7. Stage 4 :- Advanced Counting • The student’s most reliable strategy is counting-on or counting-back to solve addition and subtraction problems, or skip counting for multiplication tasks.

  8. Question 1 • 8 + 5

  9. Stage 5 :- Early Additive Part-Whole Thinking • Thestudent shows any Part-Whole strategy to solve addition or subtraction problems mentally by reasoning the answer from basic facts and/or place value knowledge. • On multiplication tasks, the student uses a combination of known multiplication facts and repeated addition.

  10. Question 2 • 29 + 7

  11. Question 3 • You have 37 lollies and you eat 9 of them. • How many lollies do you have left?

  12. Question 8 • Rohan has 8 five dollar notes in his wallet. How much money does Rohan have altogether?

  13. Question 15 • This cake has been cut into thirds. Here are twelve jellybeans to spread out evenly on top of the cake. If you eat one third of the cake, how many jellybeans do you eat?

  14. Stage 6 :- Advanced Additive Part-Whole • Thestudent is able to use at least two different mental strategies to solve addition or subtraction problems with multi-digit numbers. • The student uses a known facts to derive answers to multiplication and division problems.

  15. Question 4 • There are 53 people on the bus. 26 people get off. How many people are left on the bus?

  16. Question 5 • Sandra has 394 stamps. She gets another 79 stamps from her brother. How many stamps does she have then?

  17. Question 9 • What is 3  20 ? • Use this fact to work out: • what is 3  18 ?

  18. Question 10 • What is 5  8 ? Use this fact to work out: what is 5  16 ?

  19. Question 16 • What is of 35?

  20. Stage 7 :- Advanced Multiplicative Part-Whole • The student is able to solve addition and subtraction problems for decimals. • The student is able to use at least two different mental strategies to solve multiplication and division problems with whole numbers.

  21. Question 6 • Marija has a 5.3 metre length of fabric. She uses 2.89 metres of it to make a tracksuit. How much fabric has she got left?

  22. Question 11 • There are 6 baskets. There are 24 muffins in each basket. How many muffins are there altogether?

  23. Question 11a • It costs $1500 per square metre to build a house. The floor plan for my house has an area of 240 square metres. • What is the cost of building my house?

  24. Question 12 • At the car factory they need 4 wheels to make each car. How many cars can they make with 72 wheels?

  25. Question 12a • I have 85 roses that I want to put into bunches of 5 roses. How many bunches can I make?

  26. Question 17 • 18 is of a number. • What is the number?

  27. Stage 8 :- Advanced Proportional Part-Whole • The student uses at least two different strategies to solve problems that involve equivalence with and between fractions, ratios and proportions.

  28. Question 13 • Ivan has 2.4 kilograms of mince. • Each pattie takes 0.15 kilograms of mince. • How many patties can Ivan make?

  29. Question 18 • There are 21 boys and 14 girls in Ana’s class. What percentage of Ana’s class are boys?

  30. Question 19 • It takes 12 balls of wool to make 9 beanies. How many balls of wool does it take to make 12 beanies?

  31. Scenarios

  32. 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?

  33. 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?

  34. 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?

  35. 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?

  36. 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?
