1. Singapore Maths in Year 1
Addition and Subtraction:
Bridging through 10

2. Singapore Maths Scheme
A fundamental component of the Singapore Maths Scheme is using the children’s knowledge of number pairs for ten (1+9, 2+8, 3+7, 4+6, 5+5) to help them with addition and subtraction (i.e. ‘bridging through ten’).

3. 3 stages in any calculation
1. Concrete: using objects
2. Pictorial: drawing a picture
3. Abstract: writing a sum

4. Addition
9 + 3 =

5. 1. Concrete: use cubes for 9 and 3
3 cubes in the other egg box
9 cubes in one egg box

6. Move cubes from one box to make 10 in the other box

7. 2. Pictorial – showing working
9 + 3 = 12
1 2

8. 3. Abstract – written down
9 + 3 = 12

9. Subtraction
13 – 6 =

10. Use cubes to show the first number (13)
1. Concrete: use cubes
Use cubes to show the first number (13)

11. Move cubes to subtract the second number (6) from the ten

12. Regroup: combine all the cubes

13. 2. Pictorial – showing working
13 – 6 = 7
10 3 4

14. 3. Abstract – written down
13 – 6 = 7
