Pupil outcome: I can add two-digit numbers when the sum crosses the tens boundary Key learning points: - When adding two-digit numbers that cross the tens boundary, both addends can be partitioned, then recombined. - When adding...

Pupil outcome: I can combine and partition tens and ones in the context of equations. Key learning points: - Known strategies can be used to help us prepare for the addition of two 2-digit numbers. - It is important to be able to...

Pupil outcome: I can use knowledge of doubles to calculate near-doubles. Key learning points: - Knowing double facts helps you to calculate near-doubles. - If 2 + 2 is equal to 4, then 2 + 3 is equal to one more than 4 which is 5

Pupil outcome: I can explain that if the order of the addends is changed, the sum remains the same. Key learning points: - When the order of the addends is changed, the sum remains the same. - Addition is commutative because the addends...

Pupil outcome: I can find the missing addends when adding two-digit numbers. Key learning points: - Two-digit numbers can be partitioned to help find a missing digit or a missing addend. - One equation can be used to help solve another...

Pupil outcome: I can find the missing part in an equation. Key learning points: - Number sense and subitising skills can be used to help find missing parts. - Patterns in the number system can be used to help find missing parts. -...

Pupil outcome: I can choose the best strategy to add three small numbers together. Key learning points: - Using commutativity allows us to simplify a problem with three addends. - Using known facts allows us to add three addends...
