## 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.

### NETS Profiles for Technology Literate Students

• Use input devices (e.g., mouse, keyboard, remote control) and output devices (e.g., monitor, printer) to successfully operate computers, VCRs, audiotapes, and other technologies.
• Use technology resources (e.g., puzzles, logical thinking programs, writing tools, digital cameras, drawing tools) for problem solving, communication, and illustration of thoughts, ideas, and stories.
• Gather information and communicate with others using telecommunications, with support from teachers, family members, or student partners.

### Materials

• Digital Camera
• Printer
• Paper
• Glue

### Alternatives/Extensions

• Use the same lesson for multiplication / division facts.
