Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Third graders are introduced to different types of transformations. As a class, they describe how a stuffed animal slides across the floor and use themselves to demonstrate as well. Individually, they flip and turn in different...

Third graders read the story STREGA NONA together as a class and discuss what they know about pasta. They each receive pieces of pasta to glue down on construction paper and write beneath each one what they think it looks like.

Fourth graders participate in what is considered to be a model lesson. The lesson focuses upon polygons and basic geometry. The lesson addresses national standards and displays how others should be done.

Seventh graders investigate the mathematical concept of a sector. They apply the concept to an example problem and then move into a more complex application. They find the area of the side of a cone. This is done as students calculate...

Students measure the angles of wings and tails of various aircraft using a protractor. They estimate and check their measurements. They investigate aircraft being developed and tested at NASA Dryden.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry lesson, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their...

In this shape and figures learning exercise, students read descriptions of shapes and figures, name them and draw their pictures in spaces provided. A reference web site is given for additional activities.

In this construction geometric shapes worksheet, student use the software program for instruction then construction shapes and bisect angles for four questions.

Students measure and label specified angles. In this angles instructional activity, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct...

In this angle vocabulary card worksheet set, students identify the vocabulary associated with angles such as: ray, vertex, acute angle, segment bisector, and corresponding angles. They identify 23 terms but there are no questions...

Students describe, make and compare polygons. For this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Students, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

Given congruent triangles, the student will justify and apply triangle congruence relationships.

This multimedia Learn Alberta math resource looks at how the math concepts of similarity and congruence are utilized in the making of road signs. The accompanying interactive component asks students to manipulate triangles by dragging,...

Use Glencoe's randomly generated self-checking quiz to test your knowledge of congruent and similar figures. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check...

Students explore congruent figures and play a concentration matching game in this interactive web lesson.

Given geometric figures on the coordinate plane, the student will apply the definition of congruence, in terms of rigid transformations, to identify congruent figures. The student will also identify and distinguish between reflectional...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to write congruence statements and use congruence statements to determine the corresponding parts of triangles. Students examine...

[Free Registration/Login may be required to access all resource tools.] In this lesson students deduce information about triangles with congruence statements. Students examine guided notes, review guided practice, watch instructional...

[Free Registration/Login may be required to access all resource tools.] In this lesson students prove two triangles are congruent with the Angle-Side-Angle and Angle-Angle-Side shortcuts. Students examine guided notes, review guided...

Solve geometry problems with various triangles by using all you know about similarity and congruence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
