This presentation provides two days of teaching that cover the objectives:
- Mental addition and subtraction with single-digit numbers to big numbers
It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.
Day 1 Teaching
What is 5 + 2? 25 + 2? 425 + 2? 3425 + 2? Point out that we can use the fact that 5 + 2 = 7 to answer each of these questions. These are ‘no work sums’! Use a counting stick to show 3995 to 4005 and demonstrate 3995 + 6 then 3997 + 8. Repeat with 4200 then 4550 as the central number.
Day 2 Teaching
Write 8 – 5? 38 – 5? 738 – 5? 3738 - 5? Point out that we can use the fact that 8 – 5 = 3 to answer each of these questions. Use Post-its to mark one end of a counting stick as 6995, the other as 7005. Mark the centre as 7000. What is 7005 subtract 6? Subtract 8? And 7003 – 8? Repeat with 5600 then 3240 as the central number.
