Using Number Bonds to Show Subtraction

More

Number bonds show part, part, whole. Your child will use number bonds to solve take-away problems.

Let’s try one. Here are 5 apples. Five is the whole number. A hungry pig comes along and eats three apples! The pig took away three apples, so three is a part of our number bond. There are two apples left, so two is the other part.

Our number bond shows five apples take away three apples equals two apples. The number sentence for this number bond looks like this: Five take away three equals two.

This number bond shows us another subtraction fact, too. Five apples take away two apples equals three apples. Five take away two equals three.

Now, you can help your child with number bonds and taking away!
