Area of solids
Finding area of rectangular solids and cylinders by cutting them into flat pieces and adding the areas.
Format: lesson plan (grade 7–12 Mathematics)
By Dorothy Carawan.
Building a paper bridge: An introduction to problem solving
This activity allows the student to explore problem solving strategies while working with a partner. This activity (building a paper bridge), requires students to question word definition and the application of those definitions. Through problem solving strategies, students discover the need for applying math skills.

Giving meaning to volume and surface area
This lesson is designed to help students give meaning to volume and surface area by solving problems using a meaningful situation rather than formulas.

By Grayson Wheatley.
Inside, outside, and all around
Students will distinguish between perimeter, area, and volume. They will use tangrams and graph paper to create two-dimensional figures that will be measured for area and perimeter. By creating layers of centimeter cubes, the students will explore the concept of volume.

Investigating surface area
This is a hands on lesson best used to introduce geometry students to 3-dimensional figures. Students will have the opportunity to draw 3-dimensionally and create collapsible figures which can be used to develop the standard surface area formulas.
