What Are Related Subtraction Facts?
Related subtraction facts are subtraction problems that come from the same number family!
Just like brothers and sisters in a family, these facts are connected. If you know one subtraction fact, you can figure out its related facts too!
How to Find Related Facts
1️⃣ Start with three numbers that make a fact family (like 5, 3, and 8)
2️⃣ Write two subtraction facts with these numbers
3️⃣ Flip the numbers to make the related facts!
Let's Practice Together!
Example 1: The 5, 3, 8 Family
8
5
3
Can you find the related subtraction facts?
8 - 5 = 3
8 - 3 = 5
Example 2: The 7, 2, 9 Family
9
7
2
What are the subtraction facts for this family?
9 - 7 = 2
9 - 2 = 7
Parent Tips 🌟
- Use household objects like buttons or cereal pieces to create fact families - kids love hands-on learning!
- Make it a game: Write one fact on an index card and have your child find its related fact.
- Practice with real-life examples: "If we have 10 cookies and eat 3, how many are left? What if we eat 7 instead?"
