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...
Curated OER
Angle Action
Students measure and label specified angles. In this angles lesson plan, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This...
Curated OER
Mathematics Within: Shape, Space & Measurement
Students experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate when...
Curated OER
Wind Tunnel Aerodynamics Problem Set
Students, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by applying it to the calculation of area, velocity, and pressure in a wind tunnel.
Curated OER
Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
Curated OER
Ovals, Rectangles, Squares, and Triangles
Students identify geometrical shapes displayed in photographs of everyday objects in a metropolitan setting.
