Teaching Spring Subtract and Connect
What it is
Number bonds: a whole and its two parts drawn in circles, so subtraction is seen as finding the missing part rather than a separate operation. In Grade 1: subtracting within 20; each problem's three numbers then go into a triangle, the whole on top and the two parts below.
When a child is ready
Ready once subtraction within 20 is steady.
If they struggle
The biggest of the three numbers always goes on top. Check the triangle by adding the two bottom numbers.
