Specific Outcomes
MEASUREMENT
Suggestions for Teaching and Learning
Students will be expected to:
Shape and Space (Measurement)
5SS1 Continued...
Teachers could divide the class into groups of two or three. Give each
group 30 colour tiles. Ask them to create all possible rectangles with
an area of 30 and record the perimeter of each.
Students should find a
method to keep track of side lengths and width, and sketch the rectangles
on grid paper. Word problems could be solved and created based on the
area and/or perimeter of these rectangles. Ask:
• Do all rectangles with the same area have the same perimeter?
• Do all rectangles with the same perimeter have the same area?
• Which rectangles have the greatest/least perimeter?
• Which rectangles have the greatest/least area?
Achievement Indicators:
5SS 1.3 Illustrate that for any
given perimeter, the square or
shape closest to a square will result
in the greatest area.
The playground can be a good place for students to investigate perimeter.
First, ask students which unit of measurement they should use to measure
the playground (mm, cm, m or km). Then, have students estimate the
perimeter by estimating the number of steps they would take if they
walked around the perimeter. Record the estimates of each child. Using a
trundle wheel, find the actual measurement of the perimeter.
Creating problems based on children’s literature
allows a spring board for
thinking creatively about concepts like area and perimeter.
After reading
Pigs
by Robert Munsch, for example, pose problems related
to the construction of a new pen for the pigs such as:
The farmer has 24 m of fencing remaining from
his last project and four
fence posts. What size rectangle should he build the pen so that the pigs
have the maximum amount of play area?
Students could use square tiles to model different sized pigpens, finding
those which can be enclosed with 24 units of fencing and recording the
dimensions and area of each. Ask them to look for patterns. Ask: What
happens as the length of the rectangle changes?
What do you notice
about the pigpen that has the largest area?
Students could create a commercial jingle or a print ad for a fencing
company which guarantees their fences provide the largest area for the
amount of fencing used.
5SS1.2 Construct or draw two or
more rectangles for a given area in
a problem-solving context.
Provide students with grid paper. Ask them
to draw a square that has
sides each measuring two units. Find its perimeter and area. Share results.
Repeat with squares that have other side measurements. Ask if they see a
relationship between side length and perimeter; between side length and
area.
5SS1.4 Illustrate that for any
given perimeter, the rectangle
with the smallest possible width
will result in the least area.
5SS1.5 Provide a real-life context
for when it is important to
consider the relationship between
area and perimeter.
