2D Nets and 3D Decorative Boxes
Calculating the surface area of cardboard boxes is the focus of this interactive activity. The classroom activity takes this knowledge and asks the students for figure out how many square inches of wrapping paper is needed to wrap a gift. NOTE: You have to create a Free PBS Account to view this web page, but it is easy to do and worth the effort.
Students are introduced to all kinds of angles in this lesson plan, including acute, obtuse, right, vertical, adjacent, and corresponding among others.
Applying Angle Theorems
This lesson unit is intended to help educators assess how well students are able to use geometric properties to solve problems.
This lesson is designed to help students be able to calculate the area of a random shape on a grid, explain the correlation between the size of the perimeter and the number of different possible areas that can be contained within that perimeter.
In this lesson, students will explore the area of irregular shapes to find multiple different methods for calculating area
Boxed In and Wrapped Up
This lesson asks students to find the volume and surface area of a rectangular box and then convert it into a cubical box with the same volume.

Chris McCloud's Lesson: Expert Analysis
This Teaching Channel video highlights and critiques the techniques used in a lesson on cylinders. (14 min.)
Estimating: Counting Trees
This lesson unit is intended to help educators assess how well students are able to solve simple problems involving ratio and direct proportion, choose an appropriate sampling method, and collect discrete data and record them using a frequency table.
Estimations and Approximations: The Money Munchers
This lesson unit is intended to help educators assess how well students are able to
model a situation, make sensible, realistic assumptions and estimates, and use assumptions and estimates to create a chain of reasoning, in order to solve a practical problem.
Fences - student task
This task has students design a fence that meets the city ordinances and the client's specifications.
Grade 7 Math Module 3: Expressions and Equations (EngageNY)
This module consolidates and expands upon students understanding of equivalent expressions as they apply the properties of operations to write expressions in both standard form and in factored form. They use linear equations to solve unknown angle problems and other problems presented within context to understand that solving algebraic equations is all about the numbers. Students use the number line to understand the properties of inequality and recognize when to preserve the inequality and when to reverse the inequality when solving problems leading to inequalities. They interpret solutions within the context of problems. Students extend their sixth-grade study of geometric figures and the relationships between them as they apply their work with expressions and equations to solve problems involving area of a circle and composite area in the plane, as well as volume and surface area of right prisms.
Grade 7 Math Module 6: Geometry (EngageNY)
In Module 6, students delve further into several geometry topics they have been developing over the years. Grade 7 presents some of these topics, (e.g., angles, area, surface area, and volume) in the most challenging form students have experienced yet. Module 6 assumes students understand the basics. The goal is to build a fluency in these difficult problems. The remaining topics, (i.e., working on constructing triangles and taking slices (or cross-sections) of three-dimensional figures) are new to students.
Grade 7 Unit 4: Geometry (Georgia Standards)
The units in this instructional framework emphasize key standards that assist students to develop a deeper understanding of numbers. In this unit they will be engaged in using what they have previously learned about drawing geometric figures using rulers and protractor with an emphasis on triangles, students will also write and solve equations involving angle relationships, area, volume, and surface area of fundamental solid figures.
Great Modeling Tasks in Three Acts - File Cabinet
This surface area activity has students answer the question: How many stickies cover the cabinet?
After watching a clip of the movie Holes from Walt Disney Pictures students will answer a series of questions, such as "If Stanley and X-Ray both dig one hole per day for a year, how much extra dirt will Stanley have dug than X-Ray?" and "How many times could that extra dirt fill one of the holes X-Ray digs?"
Maximizing Area: Gold Rush
This lesson unit is intended to help educators assess how well students are able to interpret a situation and represent the variables mathematically, select appropriate mathematical methods to use, explore the effects on the area of a rectangle of systematically varying the dimensions whilst keeping the perimeter constant, as well as interpret and evaluate the data generated and identify the optimum case.
Measuring Henry's cabin
In this lesson and activity students will determine the surface area and volume of a house and also reconstruct it on a smaller scale.
Miniature Golf - student task
This task requires students to redesign a miniature golf course to make it more challenging.
Mr. McCloud: Discovering Surface Area of a Cylinder
This Teaching Channel video and lesson plan will help students discover and apply the formula for the surface area of a cylinder. (27 minutes)
Student Task: Roman Mosaic
In this task, students have to decide how you would describe the design of a mosaic pattern over the telephone.
Student Task: Circle Pattern
In this task, the student will look at a pattern of black and white circles and describe, mathematically, what is happening to the areas of black and white as the pattern develops.
Student Task: Historic Bicycle
In this task, students will figure out some problems about a strange old bicycle.
Student Task: Octagon Tile
In this task, students will explore the geometry of a pattern made by arranging squares within an octagon.
