Here’s something super easy to do with kindergartners and first graders that covers a lot of the Common Core geometry standards. You will need one geoboard per student and some geobands.

Working in small groups, ask students to design different shapes on their geoboards. Discuss the attributes of the shapes and compare different shapes such as rectangles and triangles.

Next, have students create different shapes within specific parameters. For example, design a triangle that touches exactly 4 pegs. See photo for an example. Ask if they can do it a different way. Continue with different shapes.
