This unit contains lesson plans, quizzes, and an assessment project. Students will investigate nets, which are 2D representations of 3D objects, surface areas and volumes of various prisms, and more. The project has students designing their own packaging, calculating the surface area, volume, and cost of materials, for a product of their choice.

Collection Contents


In this project, designed to be completed over 1 to 2 weeks, students will take on the role of a Product Packaging Manager, reporting to the CEO of the company of their choice. Students will select a product of their choice (XBox, PS3, iPhone, Android phone, Blackberry, iPod or other) and design a package for it, keeping in mind that the product must be kept safe and the box must be appealing to look at. The surface area and volume of the packaging will be calculated, as well as the cost of materials.

In this 80-minute lesson plan designed for Math 8 (textbook: Math Makes Sense), students will use rulers to measure the surface areas of various boxes (cereal, juice, crackers etc.). Students will use the collaborative activity, assigned questions, and quiz to understand the relationship between the net of a prism and its surface area.

In this lesson, students will discuss where they see triangular prisms in their everyday lives, and watch some short clips and a powerpoint showing examples. They will investigate the nature of a triangular prism's surface area, and how it is similar and different to a rectangular prism. There is a short quiz at the end, to be written at the start of the next class.

In this 80-minute lesson plan designed for Math 8 (textbook: Math Makes Sense), students will investigate the relationship between Length (1D), Area (2D) and Volume (3D). They will use rulers to measure the volumes of various boxes (cereal, juice, crackers etc.). Students will use the collaborative activity, assigned questions, and quiz to understand what volume is, and how to calculate it.
