  2. Find out what you need to do (add or subtract).
  3. Use objects or drawings if you need help.
  4. Write your number sentence and solve.

Why Word Problems Matter

Word problems help us think and use math in our daily lives!

Examples

  • You have 3 red balls and 4 blue balls. How many balls do you have in all?
