Teach a child the basics at a young age. Use visual clues to illustrate basic subtraction. For example, line up a row of toys and count them out loud for the child, take a toy away and count them again.
Ask your child to review subtraction homework. assignments with you. This will help solidify the basic rules and give you a chance to help her correct mistakes before they become bad habits.
Practice subtraction exercises while enjoying a day together. If a basic subtraction problem arises while you are spending time with your child, ask him to solve the problem. Making subtraction exercises into a game will get him excited about his new knowledge. (Reference 3)
Repeat subtraction exercises before bedtime. The brain stores important information in long-term memory during sleep, so before-bed practice will help your child retain the information.
