Explorations with Shapes
Students describe, identify and compare two-dimensional figures. They also name and demonstrate the relative position of objects using directional words. They sort and compare two-dimensional figures and three-dimensional objects...
Curated OER
Learn the Shapes
Students examine and identify the similarities and differences of two-dimensional shapes. They play an I-Spy shape game, participate in a classroom Shape Search, and create illustrations of shapes for a shape collage.
Curated OER
Draw It!
Students follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the...

Cap-It to the Max
Eighth graders compare the volume of three cylinders constructed from the same size sheet of paper. They use concrete and graphical models to derive formulas for finding perimeter, circumference, area, and volume of two and three...
Curated OER
Fill and Wrap It Up
Students find the surface area and volume of the solid figures by measuring the length and the height of each face and base. They use concrete models to derive formulas for finding perimeter, circumference, area, surface area, and volume...

Who Am I? (Middle School)
Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...
Curated OER
Pass It On
Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...
