Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...

Young scholars examine the correlation between art and math. Using their computers, students construct and measure angles. Young scholars identify the properties of angles and polygons. They engage in the Angles program on their Palm and...

Students work together to create mobiles with different polygons. They research the polygon and list its characteristics. They may present to the class if they chose to.

Students explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.

Students examine a variety of real life situations in which they must access information, select an appropriate formula, and calculate an answer. A rectangular piece of grass provides an opportunity for the exploration of this lesson.

Learners identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.

Students handle geometric shape puppets and answer specific questions about dimension. They write from the shape's point of view comparing themselves to everyday objects.

Students create Post-It note fundamental regions to tesselate. They make tesselations using computer software or websites. They create a jacket design with tesselation and determine the cost of production.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

If you like to play Tetris then you might like this project. You'll learn something interesting about the mathematics of complex shapes.

Test your knowledge on the attributes of triangles. There are eleven levels that may be completed with or without a timer.

In this activity the Students can use Cabri Jr. to investigate the Triangle Inequality Theorm and make conjectures about their findings.

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...
