Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

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...

Learners create tessellations. In this geometry activity, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.

Students discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.

Students explore patterns involving objects or figures and geometric shapes. They identify the missing shapes in patterns and discuss what would come next in the pattern, analyze patterns using different objects, and complete a...

Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...

Third graders incorporate math into dancing. In this algebra lesson plan, 3rd graders identify different shapes and patterns using dance movements. They relate the different creations to polygons as they incorporate the use of stretchy...

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

Young scholars investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

After identifying angles (acute, obtuse, right) during a math or science lesson, 4th graders will use the computer to stamp pictures in the correct category using KidPix computer software.

Eighth graders engage in a lesson that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as polygons.

Students identify polygons.  In this polygon people activity, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The activity may be extended by allowing...

High schoolers define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.

Students perform transformations on their graphs. In this algebra lesson plan, students identify the pre-image and image. They find and identify congruent shapes and isometry.

Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...

Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.

Fourth graders use the concept of number patterns to complete a portion of Pascal's Triangle as well as identify and describe the patterns represented.

Young scholars, in groups, identify examples of shapes around the school site. They take digital pictures of these shapes and use them to construct a class book.

Your class will use a TI calculator to drag vertices of rectangles and triangles to observe what happens to ratios of pairs of sides within each figure. They will apply the definition of similarity to identify similar shapes. The...

Students identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...
