Addition and Subtraction Facts
Chapters
In this video lesson we will recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation
Elaborations
- recognising that certain single-digit number combinations always result in the same answer for addition and subtraction, and using this knowledge for addition and subtraction of larger numbers
- combining knowledge of addition and subtraction facts and partitioning to aid computation (for example 57 + 19 = 57 + 20 – 1)
