Construct these dimensional geometrics to form various polyhedrons.
Students can make a cylinder, cone, square-base pyramid and 3-D cube for manipulatives, gift packaging, planters or games.
Reinforce a lesson on geometrics with these easy-to-assemble three-dimensional shapes.
Supplies Used: Adhesive, Cardstock or construction paper, Cotton balls or quilt batting, Eye dropper, Seeds
The teacher will die-cut the materials for student use prior to the lesson.
- To make a planter, die-cut the 3-D cube out of laminated cardstock. Mountain fold on all the perforations.
- Place adhesive on the side tab, and adhere to the opposite side of the cube.
- Fold the bottom flaps in, and leave the top flaps open.
- Place damp cotton balls or quilt batting inside the cube, and sprinkle seeds on the top for a dirtless planter. Keep the cotton balls moist with an eye dropper, and water daily.
- To make dice, die-cut the 3-D cube out of white cardstock. Mountain fold on all the perforations.
- Place adhesive on the side tab and adhere to the opposite side of the Cube. Leave the cube flat.
- Die-cut the Domino dots out of black cardstock. Adhere the dots to the sides of the cube, making sure that each opposite side equals seven.
- Fold the bottom and top flaps in to complete the cube.
- To make an octahedron, die-cut two square-base pyramids out of construction paper or cardstock.
- Mountain fold on all the perforations.
- Place adhesive on the side tab, and adhere to the opposite side of the pyramid.
- Adhere the two bases together to form an octahedron.
Geometry Grade 1
Reason with shapes and their attributes.
- Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
