Young scholars identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Young scholars identify the number of surfaces and faces on each...

Students explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

Students investigate solids. For this geometry lesson, students use toothpicks and gum drops to solve problems. They create visuals to help them see what is happening to the shapes.

Students discover what happens to their trash and garbage once it is collected off of the curb. In groups, they classify garbage and waste into seven different categories and estimate how much waste is created in each one. Using the...

Middle schoolers classify prisms according to their attributes. In this classifying prisms instructional activity, students explore different prisms. Middle schoolers generate observations of the attributes and classify the prism correctly.

Students study pyramids. In this prisms lesson, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.

Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.

Students analyze different polygons by shapes and sides. In this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Here is a way to help your charges identify circles and spheres. In this shapes geometry and technology lesson, students identify and draw circles and explain the related attributes. They recognize circles and spheres while exploring...

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Students describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist...

Third graders investigate shapes in our world. In this geometry lesson, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and conduct...

Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Students calculate the volume and surface are of three-dimensional shapes. In this geometry lesson plan, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Students investigate solid shapes. In this geometry lesson, students take pictures of solid shapes and classify their pictures according to the vocabulary terms: edge, face and vertex. Students present their findings to the class.

First graders view congruent shapes on a white board and define what congruent means.  In this congruent shapes lesson, 1st graders recognize which shapes are congruent and which aren't  Students complete a giant worksheet in...

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Students identify objects that are the same shape and size. They compare and contrast attributes of two-and three-dimensional objects using appropriate vocabulary. Pupils justify an extension of a geometric pattern to explain what was...

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
