5. A Typical Mental Warm Up...
Bingo!

6. Teaching Calculation - Remembering number facts
Lies at the heart of numeracy
Mental method is emphasised
- Remembering number facts
- Using them to work out new facts
- Understanding the relationship between ‘the 4 rules’
- Repertoire of mental strategies.
Written methods follow on
Application to real life e.g.: problem solving

7. Support Resources 100 square Multiplication Square Number lines
Whiteboard & Pen
Multi Link Blocks
Base ten - HTU

8. Know and use number bonds to 10 and 20
Addition
Know and use number bonds to 10 and 20
2 + 8 = 10
= 100
= 1000
= 30
Use a number line to count, putting the biggest number first

9. Addition 15 + 13 = Add to the next 10 and then add the extra
Add 2 numbers that bridge 10
Add to the next 10 and then add the extra
Adding 2 2-digit numbers (without bridging) =
+ 10
+ 3

10. Add two 2 digit numbers (informal method)
Addition
Add two 2 digit numbers (informal method) =

12. Know by heart subtraction facts for numbers up to 10 and 20
20 =
20 – 8 = 12
20 – 12 = 8
Subtract single digit numbers, bridging through the 10
