Students use Venn diagrams to represent classifications of shapes and to use counting arguments to find the number of objects in a given set.

In this sequencing ordinal numbers worksheet, learners cut out and paste the ordinal numbers under the four geometric shapes in order. Students solve 4 problems.

Students explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Learners walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

Young scholars explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

How can you find the area of a shape? Two shapes are provided on this simple activity which asks learners to find the area of the shapes. It's not as hard as it looks! You just have to count the squares! Before telling your pupils this...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.

Students participate in a unit on triangles. Through the unit they explore different way to make basic shapes using triangles. They also examine the basic properties of triangles and the relationships among basic geometrical shapes in...

In this geometry instructional activity, students determine what if 6 different shapes are a circle, square, triangle or a rectangle. Students bubble in their answers.

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Help your class identify right triangles using this resource. This series of slides involves pictures of clocks with hands forming right angles. It's an interesting way to introduce this topic.

Students create geometric shapes with a jump rope. In this interdisciplinary instructional activity, students review the different shapes while getting some physical activity.

In this shape and figure descriptions worksheet, students name the shape described and draw it. Students complete this for 2 shapes.

In this area activity, students figure out the area of complex shapes containing 90' angles. Students find the area for 2 shapes.

Ever played 20 Questions? A similar game helps young learners practice asking and answering yes-or-no questions. Spread out several objects, preferably all similar with slight variations (buttons or coins would work well). A leader...

For this congruent shapes worksheet, learners analyze a group of 20 geometric shapes that have letter labels. Students find pairs of shapes that are congruent in this group and write the letters of the shapes that match.

Pupils design different shaped plots and determine the perimeter, area and shape of each. They compare the shapes that have the same area but may have different perimeters.

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Young math whizzes solve four problems in which a triangle with labeled angle measurements is analyzed. They mark if each triangle is acute, right, or obtuse.

Students recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.

Students identify geometric solids.  In this shape lesson, students explore the characteristics of geometric solids.  They locate pictures of shapes on the internet, and identify the shapes.  Students draw pictures of...

Students, in groups, venture onto the schoolground on a scavenger hunt for shapes. They are given tasks: recorder, team leader, presenter, reporter, and behavior guidelines and a time limit. They search the school for shapes found in...
