Compare the amount of unit squares that cover figures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video tutorial, or receive hints related to the concept of area.

This is the second version of a task asking students to find the areas of triangles that have the same base and height. This presentation is more abstract as students are not using physical models. They still determine the area of each...

A challenging proof like geometry of finding the square inscribed in a triangle.

This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. Aligns with 3.MD.C: CCSS.Math.Content.3.MD.C.6 Measure...

Determine the value of a given fraction represented as a point on a number line. Then find a fraction whose value is the given fraction using an arrow on the number line as a guide.

The students will find the area of each two dimensional figure on a net of a square pyramid. In groups, students will cut out the net and create a square pyramid. Groups will then discuss how to find the lateral area and the total...

This interactive exercise focuses on working with the radius of various circles to find the circumference and area as well as challenging you to find the distance a square wheel travels around the track.

This resource has three sets of problems. Each set has six questions for finding area of irregular shapes formed by line segments. Select a problem set, then select a question. Fill in the blank with the correct answer for each problem....

Use this calculator to determine the volume, surface area, or other figure for a square pyramid, given the other numbers. Users set their parameters for two known variables of the pyramid and find what the unknown amounts would be.

Label the given measurements in a diagram. Find the side length of a square when given the area. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this task, 6th graders are presented with a large square divided into 9 squares and the center square is then removed. They are asked to find the area of the 8 remaining squares. Each smaller square is divided in the same way and the...

[Free Registration/Login Required] This flipchart is a review of calculating the area of squares, rectangles, and triangles for fifth graders. It also includes problems that work backwards from the area to find missing dimensions. It...

Based off of the hit television show NUMB3RS, this two-part lesson begins by having students try to find the line of best fit for a given set of data (strike outs vs. home runs). The second part of the lesson shows how least squares...

Based off of the hit television show NUMB3RS, this lesson has students explore the relationship between a circle's area and it's radius. This is framed in the context of a scene in where a pile of ice is melting into an increasingly...

Use this square calculator to find the side length, diagonal length, perimeter, or area of a geometric square. Given any 1 variable you can calculate the other 3 unknowns.

In this activity, students learn to find area and explore the quadratic function. They compare the areas and patterns of squares within a square.
