## Fact Families

Use pictures of students taken with a digital camera as manipulatives for creating fact families.## Objectives

- Students will use pictures to represent whole numbers.
- Students will understand the effects of addition and subtraction on whole numbers, including the inverse relationship of the two operations.
- Students will add and subtract whole numbers to solve real-world problems using pictures.
- Students will create fact families.
## Procedure

- Before the lesson, use a digital camera to take pictures of the kids in small groups - in their table groups, at centers, etc.
- For the lesson, have the students use two pictures to create a fact family. For example: a picture of 3 students plus a picture of 4 students equals 7. Have them use the same set of pictures to create 2 addition sentences and 2 subtraction sentences. Students can glue the pictures onto their paper and write the number sentences.
