Addition and Subtraction

Adding and Subtracting

Addition means putting things together, and subtraction means taking things away. These are the building blocks for all math!

Ways to Add

  • Count on using your fingers or number line.
  • Use objects to make groups.

Ways to Subtract

  • Take away objects from a group.
  • Use a number line to jump backward.

Helpful Tips

  • You can add numbers in any order and the answer is the same.
  • Subtracting is the opposite of adding.

Practice Makes Perfect

Try using real objects like snacks or toys to practice adding and subtracting.

Examples

  • If you have 6 apples and get 3 more, you have 9 apples.

  • If you have 10 candies and eat 4, you have 6 left.

In a Nutshell

Addition puts numbers together, subtraction takes them apart.
