Explore Fact Families: Learn with Practical Examples for Grade 3

📚 Quick Study Guide

• 🔢 A fact family is a set of related addition and subtraction (or multiplication and division) equations using the same numbers.
• ➕ For addition/subtraction, a fact family includes two addition facts and two subtraction facts.
• ➖ Example: For the numbers 3, 4, and 7, the fact family is: $3 + 4 = 7$, $4 + 3 = 7$, $7 - 3 = 4$, $7 - 4 = 3$.
• ✖️ Fact families help understand the relationship between addition and subtraction (or multiplication and division).
• 💡 Knowing one fact can help you quickly recall the others in the same family.
