# Addition and Subtraction Fact Family Lesson Plans

## Get more bang for your buck by teaching addition and subtraction fact family lesson plans.

By Greg Harrison One of the most common complaints I hear from other teachers is, “Many of my students still don’t know their basic facts.” It can be exasperating to see a fourth grader still counting on his/her fingers when trying to add two numbers together – let alone multiply or divide. Let’s face it, learning the basic addition/subtraction and multiplication/division facts is an absolute requirement for a math student to be able to achieve success. This article describes one way of teaching addition/subtraction fact families to second or third graders.

We’ll assume that 11 was the number given, so the four equations would look like this:

5 + 6 = 11

6 + 5 = 11

11 – 6 = 5

11 – 5 = 6

If one was the number given, the equations would look like this:

1 + 5 = 6

5 + 1 = 6

6 – 5 = 1

6 – 1 = 5

Using fact families gives you “more bang for your buck,” because you are encouraging students to use advanced properties of addition and subtraction, and you are getting them to learn four facts at a time – not just one! The more they do this, the more they will see how the numbers are related to each other. Below are some other lessons on fact families that I believe you will enjoy.

## Addition and Subtraction Fact Family Lesson Plans:

Triangle Town

Students create a fact family town out of triangular-shaped houses in order to develop an understanding of numbers which are "related" in fact families. This lesson lends itself well to creating a bulletin board display of the fact family town.

Fact Families

Students use pictures of themselves and their classmates (taken in class), to create fact families. For example, a picture of a group of three students plus a picture of a group of four students equals seven students. This wonderful lesson allows students to use their own pictures to create addition and subtraction number sentences.

Students explore the relationship between addition and subtraction through listening to books and using links of chain to act out what is happening, mathematically, in the story. This innovative lesson nicely ties language arts and mathematics together into a very engaging and meaningful learning experience.

Macaroni Math

Students use pieces of pasta on a paper plate to explore how addition and subtraction are related.  In this motivating lesson, students use pieces of macaroni as a manipulative in order to create different sets of four fact family sentences.
