Children's Museum of Houston - Pre/Post Classroom Activities - Nets
Students make three dimensional shapes with nets. For this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...
Curated OER
Don't Box Me In
Students explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.
Curated OER
Angles Everywhere
First graders find angles in their classroom. In this geometric figures lesson plan, 1st graders identify, describe and classify angles they see in their world. Students create pictures that contain angles and display them in the room.
Curated OER
Marshmallow Geometry
In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.
Curated OER
Poly-Mania
This hands-on activity takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Similar Shapes
In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...
Mathed Up!
Symmetry
Eleven problems provide pupils the opportunity to find the lines of symmetry or identify rotational symmetry. Scholars alter designs to make them symmetrical, learn to recognize signs that are symmetrical, and identify the type of...
Curated OER
Tiling the Classroom
Students see how to identify regular polygons, how to slide, turn and flip polygons, and why certain polygons tessellate better than others. Groups create a one foot square design to be used to tile the classroom. Great instructional...

Making a Six-pointed Star
In this polygon worksheet, students identify and create a six-pointed star by completing 6 steps. First, they use a compass to trace a circle with a given radius. Then, students draw a point on circumference of the circle and place the...
Curated OER
Mirror, Mirror
Geometry students use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...
Bowland
Mission: Rainforest
Young environmentally conscious mathematicians solve a variety of problems related to the central theme of uncovering illegal logging activities. They determine a base camp based on given constraints, investigate logging activities and...
Curated OER
Terrific Tangrams
Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.
Curated OER
Marshmallow Geometry
Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson plan, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...
Curated OER
Space Shapes
Young scholars read "Captain Invincible and the Space Shapes" by Stuart Murphy and view a PowerPoint presentation on shapes. They identify shapes presented in the book and then identify shapes found in their classroom.
Curated OER
Cut, Construct and Think 3
Students identify and create shapes. In this geometric shapes lesson, students identify various polygons and try to create new shapes using existing polygons.
Curated OER
Using R&R to Teach Mathematics
Second graders create a shape garden. In this polygons lesson, 2nd graders practice making shapes using a geoboard and read the book The Greedy Triangle by Marilyn Burns. Students also design a shape garden using construction...
