Rock Ranking
Junior geologists sort rocks and soil. They separate a sample of river gravel by size, shape, color, and other characteristics. To include Common Core standards, you could have little ones graph the number of particles in each sample.
Curated OER
Angles
Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Classify Prisms
Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.
Curated OER
Shape Detectives
Students become "shape detectives" as they identify, name, create and describe common shapes within pictures and objects found within the learning environment. Suggestions include incorporating shapes into all learning areas and daily...

Classifying Transformations
Students analyze different polygons by shapes and sides. In this geometry lesson plan, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.
Curated OER
Classifying Quadrilaterals
Students cut out three different shapes and put them in the correct categories of parallelograms, trapezoids, and trapeziums. In this parallelogram lesson plan, students explain the sums of the angles of a triangle and a quadrilateral.

Teaching Polygons using Technology
Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...
Curated OER
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...

Classifying Solids
In this geometry learning exercise, students write the name of the shape, and identify the number of vertices, edges, and faces for 6 e-dimensional shapes. Students draw 3 shapes, and classify groups of pictures.
Curated OER
Shape All Around
Learners 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. Learners present their findings to the class.
