New Kids on the Block
Second graders identify and describe in their own language, the following 2-dimensional and 3-dimensional shapes: triangle, square, oblong (non-square rectangle), circle, oval, pentagon, hexagon, diamond, box, cylinder, and sphere. They...
Curated OER
Geometry in A Box
Students identify 3-dimensional geometric shapes and list the characteristics of each. Using modeling clay, they create their own models of specified geometric shapes. Students create and design a box to store their geometric models.

Conics in Geometry
High schoolers analyze characteristics and properties of two and three-dimensional shapes in this geometry activity. They follow detailed directions to use the Cabri Geometry II Application on their TI-89 calculator to construct a...
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
Circles, Rectangles, Squares, Triangles
Students identify, compare and classify the various shapes. For this shapes lesson, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher examples of shapes...
