Learning outcomes
| # | Title |
|---|---|
| 1 | Pupils explain how a combination of different parts can be equivalent to the same whole and can represent this in an expression |
| 2 | Pupils identify structures within stories and use their knowledge of structures to create stories |
| 3 | Pupils identify the missing part using their knowledge of part whole relationships and structures |
| 4 | Pupils interpret and represent a part-whole problem with 3 addends using a model |
| 5 | Pupils create stories to correctly match a structure presented in a model |
| 6 | Pupils use their knowledge of additive structures to solve problems |
| 7 | Pupils calculate the value of a missing part (1) |
| 8 | Pupils calculate the value of a missing part (2) |
| 9 | Pupils correctly represent an equation in a part-whole model |
| 10 | Pupils explain how adjusting both addends affects the sum (2 digit numbers) |
| 11 | Pupils explain how adjusting both addends affects the sum (decimal fractions) |
| 12 | Pupils use the ‘same sum’ rule to balance equations |
| 13 | Pupils use the ‘same sum’ rule to balance equations with an unknown |
| 14 | Pupils explain how adjusting one addend affects the sum |
| 15 | Pupils solve addition calculations mentally by using known facts |
| 16 | Pupils solve calculations with missing addends |
| 17 | Pupils explain how adjusting both the minuend and subtrahend by the same amount affects the difference |
| 18 | Pupils explain how using the ‘same difference’ rule can make mental calculation easier (1) |
| 19 | Pupils explain how using the ‘same difference’ rule can make written calculation easier (2) |
| 20 | Pupils use the ‘same difference’ rule to balance equations |
| 21 | Pupils explain how increasing or decreasing the minuend affects the difference (1) |
| 22 | Pupils explain how increasing or decreasing the minuend affects the difference (2) |
| 23 | Pupils solve subtraction calculations mentally by using known facts |
| 24 | Pupils explain how adjusting the minuend can make mental calculation easier |
| 25 | Pupils explain how adjusting the subtrahend affects the difference |
| 26 | Pupils explain how increasing or decreasing the subtrahend affects the difference |
| 27 | Pupils calculate the difference using their knowledge of an adjusted subtrahend (1) |
| 28 | Pupils calculate the difference using their knowledge of an adjusted subtrahend (2) |
