Singapore Maths

Addition and Subtraction:
Bridging through 10
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 stages in any calculation
1. Concrete: using objects
2. Pictorial: drawing a picture
3. Abstract: writing a sum
Addition
9+3=
1. Concrete: use cubes for 9 and 3
9
cubes
in
one
egg
box
3
cubes
in the
other
egg
box
Move cubes from one box to make 10 in the
other box
2. Pictorial – showing working
9 + 3 = 12
1 2
3. Abstract – written down
9 + 3 = 12
Subtraction
13 – 6 =
1. Concrete: use cubes
Use
cubes to
show the
first
number
(13)
Move cubes to subtract the second
number (6) from the ten
Regroup: combine all the cubes
2. Pictorial – showing working
13 – 6 = 7
10 3
4
3. Abstract – written down
13 – 6 = 7
