After learning that the sum of interior angles for triangles is 108 degrees, take it further to show that the sum of angles in any polygon is the same! Using hexagons, pupils practice finding the measure of the six congruent angles. Make...

Tenth graders investigate the theorems of angles and lines to prove triagle sum theorem. In this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two...

Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

Bring out the inner artist with this Abraham Lincoln lesson plan. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...

Students investigate technology and its purpose in the workplace. In this geometry lesson, students design and build a paper towel structure to investigate motion and forces. They are given a restricted weight and asked to build their...

In this circles worksheet, learners fill in 6 fill in the blank statements about circles and solve calculate the answers to 13 questions involving different measurements of circles.

Students explore lines of symmetry in geometric shapes. In this geometry lesson, students construct angles using mirrors and rubberbands, then predict the number of images that will appear in the reflection. Students reproduce lines of...

In this composite figures worksheet, high schoolers solve 11 short answer problems. Students find the area of figures composed of various polygons. High schoolers find the area of each figure given a sketch of the figure with various...

Clean Up this Mess! The classroom shapes are in one big heap. Students will work in teams to come up with a way to sort the shapes by attributes and create a visual representation to model their thinking. Pictures and videos of the...

Think through what you would view as you ride around this park on a train. You are given a topographical view of a park and asked to put the pictures in order of what you would see as you ride around the park.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and then attempt practice problems on how to complete a whole picture with some missing parts.

[Free Registration/Login Required] Place the shapes on the picture outline and collect coins for each correct answer.

Use the problem solving strategy, draw a picture, to identify the characteristics described in the correct picture. Read the interactive quiz rules and then click on the "Begin" ticket. If you answer incorrectly you get one more chance...

Congruent means, "same size, same shape." Find out more about this concept at this test prep site with real world examples and pictures. Hands-on classroom activity and lots of practice. Knowledge of basic algebra and geometry concepts...

The focus of this series of lessons is to engage students in an exploration of the world around them. The emphasis is on inquiry as students learn about the earth, sun, light, shapes and more.

[Free Registration/Login Required] Students are given a picture of shapes and are to create the same picture by adjusting the size of the shapes on the grid. Click learn more to watch a video and click challenge me to answer a practice...

Investigate the concept of symmetry at this test prep site. See detailed definitions and picture examples, answer the questions in the interactive practice pages, and do the classroom activity where students use a digital camera to...

In this interactive students click on one of the black statues to break them down into shapes; then they reconstruct the statue by putting the puzzle pieces together, which shows the animal that it represents and replaces the statues...

Great elementary level math activities, organized by school grade. Activities are sometimes written in the form of teacher instructions, with pictures and examples. Others are written directly for students and can be done online or...

Students will use a square to investigate other polygonal shapes that can be formed. Students will work with these polygons to make designs that will later constitute cooperatively designed quilts. The quilts will be made by translating,...

Picture a roll of toilet paper; assume that the paper in the roll is very tightly rolled. Assuming that the paper in the roll is very thin, find a relationship between the thickness of the paper, the inner and outer radii of the roll,...
