Ship Shape
Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.

That's So Square
Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the instructional activity, they sketch each shape and...

Congruent Polygons: Copying Stretchy Shapes
Third graders investigate congruent polygons through dance. In this congruency instructional activity, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent...
