3D geometric Shapes
Learning Goal: We are learning about 3D solids
Success Criteria: We know we have achieved this when...
Success Criteria: We know we have achieved this when...
- We can identify the names of solids (cube, rectangular prism, triangular prism, pyramid, cone, sphere, cylinder)
- We can identify their properties (number of faces, edges and vertices and whether they stack, roll or both)
- We can give examples of every day objects that are in the form of solids
- We can find differences and similarities among solids by identify sorting rules and naming sorting rules
- We can construct solids using materials
- We can communicate our understanding using mathematical language
key words:
Solid: having three dimensions (length, breadth, and thickness), as a geometrical body or figure.
Pyramid: a solid having a polygonal base, and triangular sides that meet in a point. Prism: a solid having bases or ends that are parallel, congruent polygons and sides that are parallelograms. |
Edge: line along which two faces or surfaces of a solid meet
Vertex/vertices: a point in a geometrical solid common to three or more face (a corner). Face: a face is a flat surface that forms part of the boundadry of a solid object. |
3D solids
****NOTE: If the solid has a curved face, please state so! For example, a cone has two faces, but one is curved. The other is flat.****
SPHERE
0 faces 0 vertices 0 edges RECTANGULAR PRISM
6 faces 8 vertices 12 edges |
CONE
1 faces (1 flat) 0 vertex 0 edge TRIANGULAR PRISM
5 faces 6 vertices 9 edges |
CYLINDER
2 faces (only 2 flat) 0 vertices 0 edges SQUARE-BASED PYRAMID
5 faces 5 vertices 8 edges |
CUBE
6 faces 8 vertices 12 edges TRIANGLE-BASED PYRAMID
4 faces 4 vertices 6 edges |
Let's Practice
make a skeleton!
Try to make some of the structures from above using toothpicks, straw, and playdough! Count the edge, faces, and vertices! How are some of these shape similar or different?!
