Figure out the correct name for different three-dimensional shapes by watching the presentation on solid figures. Go through the main figures and read about the characteristics of each. Finish the topic with a multiple choice online...

Tenth graders calculate the area and the volumes of polygons. In this geometry lesson, 10th graders review the formulas used to solve for the area and volume and explain to the class how they arrived at their answer. They search online...

In this areas and volumes worksheet, students find the area of truncated cones and elliptical cylinders.  They find the area by using one of three methods:  the disk method, the shell method, and using geometry.  This...

In this reflections and rotations instructional activity, students reflect and rotate lines in graphs and draw lines of symmetry through patterns. Students complete 24 problems.

Tenth graders explore volume and surface area through percentages. For this geometry lesson, 10th graders analyze the surface area of two and three dimensional shapes, then use percents and ratio to compare the two.

Middle schoolers compute area.  In this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each. 

Here is a way to help your charges identify circles and spheres. In this shapes geometry and technology lesson, students identify and draw circles and explain the related attributes. They recognize circles and spheres while exploring...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Students investigate cubes. In this geometric solids lesson, students review geometric concepts previously taught, then logon to a computer game in which they find cube figures and identify the shadow of hidden cubes.

Fourth graders use computer drawing tools to create a house of geometric shapes.

Students explore regular geometric shapes. In this shapes lesson, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.

For this geometry worksheet, students examine a picture that has many hidden triangles. Students count the triangles they discover and color the picture.

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

A complex question looking for the total cost of a stained glass window by calculating area and circumference of a circle. With detailed components, this activity will challenge your designers to figure out if they have enough money to...

Learners study facial symmetry. They explore lines of symmetry, and create illustrations with multiple lines of symmetry.

Students explore language arts by participating in a shape identification activity. In this geometry shape instructional activity, students discuss the vocabulary terms used to describe the location of an object. Students complete a...

Third graders evaluate the attributes of cones. In this space shapes lesson plan, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.

Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Students view and discuss a video about the use of pattern block shapes to form pictures. They, in groups, form garden and quilt designs using pattern blocks and then decorate the room with their art.

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

Students work collaboratively to design and construct a roof out of Legos for a house that was built in a previous lesson plan. The roof must be structurally sound and pass certain criteria determined by the teacher.

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
