Number bonds are a basic, important foundation for understanding how numbers work. A whole thing is made up of parts. If you know the parts, you can put them together (add) to find the whole. If you know the whole and one of the parts, you take away the part you know (subtract) to find the other parts.
Number bonds let children see the inverst relationship between addition and subtraction.
