Fact Family Photos

A fact family has three family members which are numbers. They can be arranged to make number sentences.These three numbers are related. Help your child see number sentences when they look at a number bond.https://www.youtube.com/watch?v=EZzrfuAomn8Let’s use this number bond to write four different, but related, number sentences. Three plus four equals seven. Four plus three equals seven.Don’t forget about subtraction! Seven minus four equals three. Seven minus three equals four.Number bonds are a great way to show relationships in a fact family using addition and subtraction. Remember these relationships! Your child will continue using fact families for multiplication and division later on! 

Grade 1 Common Core Standards

Operations & Algebraic Thinking: Understand and apply properties of operations and the relationship between addition and subtraction.

(1.OA.3) Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.) Student need not use formal terms for these properties.(1.OA.4) Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8. Add and subtract within 20.
