What a View!
Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...
Curated OER
Shape All Around
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.
Illustrative Mathematics
Lines of Symmetry for Triangles
What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
Curated OER
Poly-Mania
This hands-on lesson 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:...
Curated OER
Classifying Plants and Insects
Art and science come together in a lesson based on Flower Still Life by Ambrosius Bosschaert the Elder. Learners classify plants and insects in the painting by color, leaf shape, size, reproduction, and season of bloom.
Curated OER
Sorting and Classifying Concrete Objects by Varying Attributes
First graders examine how to sort concrete objects by their attributes. In this sorting lesson plan, 1st graders listen to Gray Rabbit's Odd One Out by Alan Baker, and discuss the actions of the main character. They practice sorting...
Curated OER
Clearly Classified
Young scholars review the classification system for living organisms and apply it the classification of insects and flowers in the still life by Ambrosius Bosschaert. They create a chart classifying the animals and plants in the painting...
Curated OER
Collecting and Classifying Pollen
Students collect and analyze pollen from different species of plants. In small groups, they classify pollen according to shape, size and physical characteristics. They draw the basic anatomy of flowering plants and create a dichotomous...
Curated OER
Straight and Curved Shapes Venn Diagram
In this math worksheet, students classify the shapes according to the correct category concerning having straight or curved sides.
Curated OER
2D Shape Sheet
In this polygons worksheet, students examine 20 different polygons that are quadrilaterals. It is not clear what they are to do with them.
Curated OER
Shape Up!
Students investigate measurement through the use of literature through this series of lessons.
Curated OER
Make Your Own Shape Puzzles
Students create their own shape puzzles. They practice putting puzzle pieces together so they fit correctly. They classify and sort the different shapes as they finish the puzzle.
Curated OER
ESOL Shape identification
Students review vocabulary shape cards. They match oral words of shapes with flash cards then they make and label their own set of shape flash cards and then review with a classmate.
Curated OER
Listen to a Shape
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.
Curated OER
Shape Walk
Students take a field trip to a local park or beach to collect objects. They practice counting the objects and put them into categories according to type of shape like a cone, cylinder, etc... As an extension to the lesson plan students...

Exploring Quadrilaterals
Sort this resource into the Use pile. Scholars investigate attributes of quadrilaterals and then use the results to sort and classify the shapes labeling each figure with their properties to justify the classifications.
Curated OER
Supplementary, Complementary, and Vertical Angles
By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...
Curated OER
Name that animal
A great way to classify organisms, is by counting the number of legs it has or how it moves. Little ones count the legs on five different creatures, then match the leg count to the proper animal name. Tip: Have them come up with other...
