How do you learn subtraction facts?
Students learn subtraction after they understand addition and counting. Addition is the process of combining while subtraction is the process of “taking away” or finding the difference between two numbers. Showing how subtraction works with objects can reinforce this concept. For example, showing your child three blocks and asking them to count how many blocks are left if you take one away. Next, show your child how to illustrate this subtraction problem by writing it out with numbers so that 3 – 2 = 1. Once your child is comfortable with the smaller subtraction facts, you can begin to work with larger numbers.
