Understanding Subtraction Sentences

Subtraction is like taking away!
When we complete subtraction sentences, we're finding the missing number that makes the equation true. It's like solving a fun puzzle with numbers!

How to Find the Missing Number

1️⃣ Look at the numbers you know in the problem

2️⃣ Figure out what's missing - is it the first number, the number being subtracted, or the answer?

3️⃣ Use addition to help find the missing number!

Let's Practice Together!

Example 1

25 - = 13

Example 2

- 18 = 27

Parent Tips 🌟

  • Use real objects: Have your child subtract with small toys or snacks to make it concrete and fun!
  • Relate to addition: Show how subtraction is the opposite of addition (if 25-12=13, then 13+12=25).
  • Make it a game: Create flashcards with missing numbers and turn it into a race against the clock!
