#### Math facts or those created using the same set of numbers is what we call fact families in mathematics. It shows the relationships between the three numbers involved. In an addition and subtraction fact family, there are four addition and subtraction sentences created using just three numbers. Fact families are three related integers, just like people in a family are related. Some families are related through addition and subtraction. Other families can be related through multiplication and division. Bar diagrams are the useful tools for students. These provide visual help them, making performing basic calculations simple and easy. It ensures that students grasp the concept and understand what is happening in the problem.

Bar diagrams provide students with a great visual to help them perform basic calculations. It really insures that they understand what is happening in the problem. Fact families are three related integers, just like people in a family are related. Some families are related through addition and subtraction. Other families can be related through multiplication and division. These worksheets explain how to construct and use fact family bar graphs. Students will write multiple equations to express a fact, and complete an associated bar graph.
