In this Area of a Parallelogram instructional activity, students are asked to solve for area graphically and mathematically.  Students are provided with geometric figures to work with.

Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....

A straightforward approach to teaching complex numbers, this lesson addresses the concepts of complex numbers, polar coordinates, Euler's formula, De moivres Theorem, and more. It includes a practice problems set with odd answers...

Can you see your class working on spatial visualization? The first installment of a five-part module introduces the concept of spatial visualization and provides a 12-question diagnostic assessment to test spatial visualization skills....

It is easy to find the area of a triangle where the base and the height are given. But in this resource, it is up to your geometers to identify the base and height of the triangle. In fact, your pupils will learn that there are three...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

This two-part reading comprehension exercise asks kids to read a short passage about cubes, rectangular prisms, spheres and pyramids, and then to respond to a series of questions about the article.

Young mathematicians find the surface area and volume of a square pyramid and a cone. In what looks like a typical activity out of a textbook, you'll find an activity where learners find an unknown measurement of a pyramid or...

If cubism were a religion, would you follow it? Lower-level tasks focus primarily on counting the number cubes in a structure and relating the number to surface area. As learners progress to higher-level tasks, isometric drawings and...

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

Fifth graders explore three-dimensional figures. As a class, they discuss the characteristics of various three-dimensional figures. In groups, 5th graders write riddles describing the geometric shape. Partners read each other's...

Young scholars listen to a poem that includes directions to use geometric figures to complete a creative task.

In this area worksheet, students calculate the area of 4 compound figures. A reference web site is given for additional activities.

In this 2 and 3 dimensional figures worksheet, students determine whether given shapes are regular or irregular. A reference web site is given for additional activities.

Students explore geometric patterns. Given three straws of various sizes, students conduct tests, and search for patterns, to determine if the various sizes would form a triangle. They use the Triangle Inequality Theorem to determine...

In this nets of 3 dimensional figures activity, students determine which given figures will make given nets, then name a set of 4 shapes.

In this nets of figures worksheet, students determine which given shapes will make a shown net, then name the shapes uses. A reference web site is given for additional activities.

For this geometry skills worksheet, students follow the provided instructions to cut out geometric shapes on the worksheet and build 5 shapes out of the pieces. Students also complete a graphic organizer regarding the shapes and their...

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding symmetry. Students may view the correct answers.

Students identify geometric solids.  In this shape lesson, students explore the characteristics of geometric solids.  They locate pictures of shapes on the internet, and identify the shapes.  Students draw pictures of...

In this geometric shapes worksheet, students analyze the colored attribute blocks and find the figures that can be made by combining those blocks. Students color the figures that are possible to make and draw an X through the ones that...

Fourth graders make models of three-dimensional figures and then use these play dough figures to observe and count the vertices, edges, and faces of the figure.

Students investigate the elements of a pattern.  In this geometry lesson, students identify different shapes in a pattern and discover which shapes are missing in order to extend it.  Students create their own patterns using...
