SHAPE AND SPACE 3 Dimensional Shapes Check up and Challenge EXPLODING OUR UNDERSTANDING OF POLYHEDRONS (“pssst...what’s a polyhedron again?” “It’s a solid with flat faces and each face is a polygon -meaning no curved sides!” “Oh yeah, thanks” :) Name: ____________ Date: _____________ Skills Used: observation, analysis, critical thinking, synthesis (putting it together), measuring cm/mm and angles accurately, addition and multiplication, spatial thinking, fine motor skills Task: First you will choose two shapes to work with. Next you will draw these two shapes as accurately as possible in 3D. Then you will define all their properties. Last you will describe the shapes in as much detail as possible Octahedron Dodecahedron Cross-section Irregular Pentagonal Prism Cross-section Tetrahedron Triangular Prism 1) Draw the shape as best as possible in 3D A) B) 2) Use a ruler and a protractor to measure Vertices: ____________ Vertices: ____________ Edges: ___________ Edges: ___________ Faces: ___________ Faces: ___________ Total number of angles: ____________ Total number of angles: ____________ Degree of 1st angle ____________ Degree of 1st angle ____________ Degree of 2nd angle: ____________ Degree of 2nd angle: ____________ Degree of 3rd angle: ____________ Degree of 3rd angle: ____________ Length of 1st edge: ____________ Length of 1st edge: ____________ Length of 2ndedge (if different): ___________ Length of 2ndedge (if different): ___________ Length of 3rdedge (if different): ___________ Length of 3rdedge (if different): ___________ Total length of the perimeter (edges) of the shape: Total length of the perimeter (edges) of the shape: ____________ ____________ Write a full description as detailed as possible about the shape (impress us with your critical analysis skills!!!!) Write a full description as detailed as possible about the shape (impress us with your critical analysis skills!!!!) This is your problem solving area where you do your equations and work through your thinking
