Word problems show us how math connects to real life. In this lesson, we practice solving addition and subtraction problems where the numbers and answers are 20 or less.
Look for words that tell you whether to add (put together) or subtract (take away).
When we add, we find the total, also called the sum. When we subtract, we find what is left, called the difference.
Words like in all or together mean add. Words like left, take away, or how many are still mean subtract.
We can break numbers into parts, called decomposing, to make adding or subtracting easier. This helps when working with bigger numbers.
Breaking apart numbers helps you use facts you already know, like making a ten, to solve problems faster.
We can use pictures, counters, or real objects to model word problems. This makes it easier to understand what is happening.
Use buttons, coins, or blocks to act out the story before solving with numbers.
We use addition and subtraction in everyday life, such as when sharing food, counting toys, or keeping track of scores.
Make up your own word problems using toys, food, or things you see around you. Then solve them by adding or subtracting within 20.
