Students study related addition and subtraction facts. In this math lesson, students use related addition and subtraction to solve problems. Students use manipulatives to explore fact families.

Students explore the concept of fractals. In this fractal lesson, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

In this line and angles worksheet, students explore basic geometry vocabulary.  They classify polygons.  Students determine the area and perimeter of given shapes.  They examine the parts of a circle, find volume and...

Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...

Third graders represent fractions as part of a whole. In this fractions instructional activity, 3rd graders use manipulatives to show how a fraction is a part of a whole. This instructional activity includes individual practice and an...

Students practice figuring out how items have been sorted. They also sort buttons in small cooperative groups. They color and sort their own paper buttons and then give their button sort to another student to see if he or she can figure...

Learners use Venn diagrams in order to classify different objects and numbers. They then use "Venn Diagram Shape sorter" applets on the computer.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.

Fifth graders work with polygons.

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

Sixth graders explore characteristics of two and three-dimensional figures. They observe the teacher demonstrate the faces, edges, vertices and names of specific figures. In groups, 6th graders examine and describe given figures. ...

Students create a binomial system of nomenclature for classifying organisms they encounter in a field trip to a natural history museum or from pictures in library books. They work in small groups to create accurate drawings and place...

Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.

Fifth graders participate in a review game of geometry topics. In this geometry lesson plan, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to...

Classify shapes based on pictures or attributes, such as angle types and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This multimedia that includes a short video [1:19] and other interactive activities on Learn Alberta math resource looks at real-world examples of shape classification in the investigation and solving of crimes. The accompanying...

Look at the properties of 2D shapes to see which shapes can belong to the same group. Includes hints.

[Free Registration/Login Required] Students will click on the point of the word and drag it to the correct figure. Click challenge me to answer practice questions and click learn more to watch a video.

Assess learning of polygons and perimeters with this interactive multiple choice practice and quiz activity. Click the question mark for hints.

This tutorial provides illustrations for regular 2-D shapes as well as a definition for polygons and for regular polygons.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on classifying rectangles, squares, circles and triangles.

Did you know that two-dimensional shapes are also called polygons? This lesson describes the various 2-D shapes and includes two interactive games to reinforce skills.

Use Glencoe's randomly generated self-checking quiz to test your knowledge of two-dimensional figure-polygons. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the...
