Stage 3 units
Unit 1 ●
This unit focuses on securing recall of:
[a] additive facts for numbers from 5-10 scaled by ten (RtP 3NF–3 scaling number facts by 10)
[b] additive facts that bridge 10 scaled by 10
[c] multiplication and division facts from Year 2 (2, 5 and 10 × tables).
Children need to be able to automatically recall the additive facts. They now combine these facts with unitising in tens. For example:
5 + 3 = 8 so 5 tens + 3 tens = 8 tens and 50 + 30 = 80.
Unit 2 ●
The unit focuses on developing fluency in three core methods for addition and three for subtraction. The methods for addition are making the next ten, partitioning both addends and the relationships method. The methods for subtraction are making the previous ten, partitioning the minuend and the relationships method.
Unit 3 ●
This unit focuses on developing fluency in multiplication facts. The primary focus is on multiplication facts, but there is also some work on division facts.
The unit focuses on the 4, 8 and 3 × tables.
Unit 4 ●
This unit focuses on providing more practice in securing recall of additive facts that bridge 10 scaled by 10.
Children need to be able to automatically recall the additive facts. They now combine these facts with unitising in tens. For example:
5 + 6 = 11, so 5 tens + 6 tens = 11 tens
50 + 60 = 110 = 110
