Geometry and Shapes in the X-36
Students describe, draw, and classify shapes. They use the internet to research the X-36 aircraft. Students identify the geometric shapes in the aircraft. They calculate the number of sides in an x-36.
Math Drills
Classifying Prisms and Pyramids
Young geometers identify prisms and pyramids based on the number of edges they have. Answers vary from hexagonal and rectangular prisms to pentagonal and octagonal pyramids.
