Shape (3D) Starters:
Dice Nets: Determine whether the given nets would fold to produce a dice.
Faces and Edges: Find the number of faces, edges and vertices on some familiar objects.
Icosahedron: How many triangles are there on the surface of a regular icosahedron.
Mirror SketchUp: Can you sketch the given 3D shape to show what it would look like in a mirror?
A particular skill is required to be able to excel in this area of Mathematics. Spatial awareness is important for solving multi-step problems that arise in areas such as architecture, engineering, science, art, games, and everyday life. Children have varying abilities visualizing three dimensional relationships but these abilities can be developed through practical activities and working through mathematical problems. Breaking down three dimensional situations into smaller two dimensional parts in an important strategy for problem solving.
