MATHEMATICS 5 CURRICULUM GUIDE 2015
Specific Outcomes
2-D AND 3-D GEOMETRY
Suggestions for Teaching and Learning
Students will be expected to:
Shape and Space (3-D Objects and 2-D Shapes)
5SS5 Continued...
Faces are the flat surfaces of a 3-D object. Edges are where two faces
meet or intersect. Adjacent faces of a cube are perpendicular and
opposite faces are parallel.
Working
in small groups, students could stack pattern blocks to build
prisms like the samples below.
Ask students questions such as:
• Which solid has the most parallel faces?
• Which solid has the least number of edges?
• Which solid has only two parallel faces?
• Which solids have eight intersecting edges?
• Which solid has four sets of parallel faces?
Achievement Indicator:
5SS5.5 Identify parallel,
intersecting, perpendicular,
vertical and horizontal edges and
faces on 3-D objects.

Interview
•
Using a variety of geometric solids, ask students to identify parallel,
intersecting, and perpendicular edges.
(5SS5.5)
Observation
•
While students are performing the stacking activity described on the
previous page, circulate and look for evidence that they are able to
correctly identify the edges and faces specified.
(5SS5.5)
Performance
•
Ask students to construct 3-D shapes using
popsicle sticks or nets
and use paint or colouring to highlight given properties. This may
also be accomplished by using coloured stickers or sticky notes to
indicate specific relationships between faces or edges of wooden or
plastic models, such as Platonic solids or blocks.
(5SS5.5)
•
Ask students to explore the classroom to identify and accurately
describe parallel, intersecting, perpendicular, vertical and horizontal
edges and faces on 3-D objects. Students may record this
information on a 10 flap foldable created by folding a right hand
page in their exercise book in half vertically. Cut from the free edge
of the page to the fold to make flaps.
The outside pieces would be
labelled: parallel edges, parallel faces, intersecting edges, intersecting
faces, perpendicular edges,
perpendicular faces, vertical edges, vertical
faces, horizontal edges, horizontal faces. The inside section would
contain specific examples of each found in the classroom; e.g.,
parallel edges - the left and right
edges of my math textbook; parallel
faces - the top and bottom cover of my science textbook; horizontal
edges - the top and bottom edges of the SMART board.
