Exploring Fact Families in Addition and Subtraction

The video tutorial introduces the concept of fact families, which involve three numbers that can form two addition and two subtraction problems. The teacher explains how to identify the largest number for addition and subtraction, using examples with numbers 6, 2, and 4. The lesson includes a class activity where students create their own fact family problems using the number 12. The tutorial concludes with instructions for students to post their solutions on a shared platform for class review.
