Circles to Spheres
Learners investigate circles and spheres. In this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Learners investigate the relationship between plane and space shapes.
Curated OER
Shapes with Sticks
Third graders investigate three dimensional shapes. They examine a variety of shapes and the relationship between the number of faces, edges, and vertices. Students determine Euler's formula and they create a variety of three dimensional...

Geo Jammin' - Day 2, Lesson 6: Rhyme and Reason
Young scholars listen to the poem "Shapes" by Shel Silverstein in order to accurately and specifically describe shapes' rules/traits in their journals. They illustrate the poem and take turns reading during a creative shared reading...
Curated OER
Scale Factor- Surface Area and Volume
Students calculate the surface area and volume of shapes. In this geometry lesson, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales and shapes.
Curated OER
Area
Students use different shapes that represent tangrams to determine the area of a space. In this area lesson plan, students trace shapes and have their partners determine the area of that shape.
Curated OER
Pythagorean Theorem
Students investigate the Pythagorean Theorem. In this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right triangle.
Curated OER
Polygon Sum Conjecture
Students calculate the sum of the angles of a polygon. In this geometry lesson plan, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.
Curated OER
Copy Cat
Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Cubic Volume
Fifth graders record measurements and calculate the volume. They select and use appropriate units and procedures to measure volume # use tools such as technology to solve problems

Geo Jammin' - Day 3, Lesson 9: Attribute Attitude
Second graders read poetry and build their vocabulary through use of the puppet Geo George.
Curated OER
Pattern Blocks
First graders examine a bag full of standard pattern blocks in the following shapes: triangle, hexagon, small rhombus, large rhombus (parallelogram), square, and trapezoid. They discuss the similarities and differences among them, count...
