Our Geometric World
Third graders explore the attributes of polygons. In this geometric shapes instructional activity, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons....
Curated OER
Levers
Young scholars brainstorm if they think that any lever would use the same amount of paperclips. They break into small groups and use a data sheet as well as a lever, Lego person, fulcrum, and some paperclips and prove what they think by...
