Using a Graph to Find Area. In this activity, you will be using a sample of ordinary poster board with uniform thickness to study area. Since the thickness is constant, you can measure the mass and area of rectangular poster board samples and graph the data to find a relationship between mass and area (mass/area). Using the graph, you will then be able to find the unknown area of an irregularly shaped sample of poster board.

### Composing and Decomposing Area - Composite Shapes

Teaching kids to find the area of composite shapes- math unit for teaching area. Hands-on, engaging math activities to help kids understand how to find the area of composite shapes.

Workshop Wednesday: Math-Area - great ideas for teaching area concepts with graph paper

Here's a project where students use a choice board to complete a project to "showcase" a special number. This project is used while teaching prime and composite numbers, factors, multiples, even and odd numbers, and prime factorization. Includes instructions for the teacher, the student page that explains the project in detail, and the grading sheet used to evaluate the project.

### Surface Area Foldable Notes and Practice

A structured approach to teaching surface area can make it so much easier for students to understand! These materials lend themselves to use in interactive notebooks. These foldable notes, examples, and practice problems feature a structured step by step format to guide student thinking as they calculate the surface area of each figure. Students will find the surface areas of prisms, pyramids, cylinders, cones, and spheres.
