Lesson Summary

Students will see relevance of numbers in measurement by trying to describe
objects without using numbers.

Measure objects using different referents. Discuss varied responses to show the
importance of standardization.
Lesson Plan
A World Without Numbers
Discuss what the world would be like without numbers. How would you describe
lengths? How would you compare? Consider sharing the story “Neil’s Numberless
World” by Lucy Coats.
Activate prior knowledge through discussion of situations where students may have
already measured without tools using a referent (e.g. football yards, golf estimates,
etc.)
The goal is to discuss the need for referents as an estimation tool.
Using Referents
Prepare an activity where students would measure various objects using referents of
their choice (e.g. body parts, common objects at hand, etc.). To differentiate you
could suggest 10 objects and ask students to choose 5 (see Going Beyond for
enrichment opportunities). Then compile results to investigate the need for
standardized measure. Once students choose a referent they should record it on the
My Referent Table handout (See Appendix).
Try to ensure students are measuring common objects with a
variety of lengths. This will lead to the need for a standard.
Mathematics 10C
Measurement
Page 21 of 47
The Need for Standards
A separate activity that could be included with the previous one is to have students
measure the same object using the same referent (hands, for example) and
investigate if this is standardized enough. If not, how could the system be improved?
Consider asking for the My Referent Table (See Appendix) as an exit slip.
Going Beyond
The choice of objects would be a great way to differentiate this lesson. To enrich you
could choose objects that are very small, or ones that are larger and/or slightly beyond
their reach. For example, the width of coins, the height of a wall or gym etc.
When completing the third column of the My Referent Table handout, encourage
examples of items not used during the classroom activity.

Lesson Summary

Students will become familiar with units of Imperial and relate these to their
referents.

Students will be able to determine appropriate units to measure varying lengths.

Have students estimate and measure objects using Imperial measurement tools.
Lesson Plan
Imperial Standards
Measure a medium sized object (exactly 3 feet) using the student’s medium referent
from the previous day. Have students compare their results. Point out that “Sarah” is
queen and her referent is the correct one. After introducing this standard ask students
to try and relate their measures to hers. This leads nicely into the video on body
measures.
My Human Ruler
Introduce students to measuring tools that are in Imperial units focusing only on whole
numbers. Using appropriate tools have students develop a human ruler, deciding
what part of their body best compares with an inch, foot and yard. Record decisions
on My Human Ruler (see Appendix).
The intent here is to assist students to better estimate lengths with Imperial
units.

Fraction Strip
Start a discussion around lengths that aren’t whole numbers? We can estimate these,
but how do we get exact lengths? Show students how to measure within an inch. A
suggestion would be to utilize fraction strips. Start with a strip of paper, define it has a
unit length, and then fold it in half to show measuring accurately to a half of an inch.
Then show folding it in half again to develop an accuracy of a quarter of an inch. Point

Practise Measuring
Have students measure a few objects; the objects from the previous day would be
ideal. If you have students measure the same objects as you could have them
compare the measurements between the referent and the Imperial System.
Build-a-box
A closing activity would have students demonstrate that they know how to measure
with Imperial measuring tools. For example, build a box that would be able to store a
certain object with little wasted space. Have a box that will store an object so that the
object is unable to move. Students will have to take measurements of the box and
then use their measurements to construct a replica of the box. Test the accuracy of
measurements by testing the fit of the object. Have students journal the steps they
took in creating the box to develop communication skills. Encourage students to
discuss the need for accuracy in their measurements.
The use of this box could be carried forward to future lessons regarding Metric
System, Surface Area and Volume.


Have students estimate and measure objects using metric measurement tools.
Lesson Plan
Imperial vs. Metric
Begin by highlighting some of the difficulties within the Imperial system. For example,
when dealing with the fractions of an inch, adding measurements together is difficult
for some. Conversions within the Imperial System are not straightforward and the
ratios would need to be memorized. See Conversion Chart in Appendix.
My Human Ruler
Introduce students to measuring tools (ruler, measuring tape, metre stick) that are in
metric units. Using appropriate measuring tools have students develop a human ruler,
deciding what part of their body best compares with a centimetre and metre. The
intent here is to assist students to be better able to estimate lengths. Have students
record their decisions on the My Human Ruler handout. (See Appendix)
Practise Measuring
Have students measure a few objects. The objects from the previous day would be
ideal. If you have students measure the same objects as they did using their referents
you could have them compare the measures between the referent, Imperial and the
Metric System.

Importance of Conversions
Discuss conversions within the systems to help students understand the process. To
help students understand the purpose behind conversions you can engage in a
discussion around 2-D and 3-D real life situations. For example, after purchasing a
shelving unit from “IKEA”, you see the box dimensions are 4 inches by 72 inches by
114 inches. If you are unfamiliar with the inch measurement, it is hard to judge
whether the carton will fit in the back of your car. If we could convert the inches to feet
it would make it easier to estimate.
Proportionality Activity – “How many … in a …”
To help students develop the comparison between measurements using their
referents, have each student determine how many “human inches” will fit in a “human
foot.” (Basically, compare how many thumb widths to their foot). In comparing
results, ideally students will come to a consensus that 12 inches will fit in a foot. Once
this has been established have students extend this knowledge to how many inches fit
in 2 feet or in 3 feet. What if it was 2.5 feet? After students have developed a strategy
for these conversions you could provide them with conversion factors (see conversion
chart in Appendix) for other lengths to practice with. The hope is that students will
discover the idea of proportionality.
Sample Problem
Another problem to present to students would be comparing two runners, one running
a mile in 15 minutes and the other running 1000 yards in 12 minutes. Which runner
ran further? Faster?
Mathematics 10C
Measurement
Page 33 of 47
Importance of Conversions Between
For conversions between imperial and metric you could begin by discussing the need
for this, and the need to communicate in a common language. Examples of this
include: Speed limits in different countries, lengths of material, volumes of quantities,
etc.
Ask students to explore the following proportions:




How many cm in an inch?
How many inches in a cm?
How many feet in a metre?
How many metres in a foot?
Follow up by illustrating the number of centimetres in an inch using the “Inch vs.
Centimetre Image” (see Appendix) and highlight known proportions on the
“Conversion Chart” (see Appendix).
Practise Conversions
Provide students with opportunities to practise conversions (refer to textbook).
Encourage the continued use of referents and estimation to verify the reasonableness
of all answers.
Tip: Check the reasonableness of answer by recognizing that a greater number of
smaller units is required to express an equivalent measure in larger units.
Going Beyond
Have students look up other units. The focus has been on linear units. Students could
look into 2-D and 3-D units (the names, the conversions).
Challenge students to do conversions of large numbers in scientific notation.

Provide students with a list of measurements already converted. Make some with
mistakes so that they have to determine which are done correctly and which need to
be corrected.
Students should attempt some conversions and then check their answers using
referents and measurement tools.
Use the box that students created (See Lesson 2) and check the accuracy of their
Imperial and Metric measurements by converting both ways.

Lesson Plan
Review Surface Area
Students should have an understanding of surface area of prisms and cylinders from
Junior High.
To begin this lesson it would be worthwhile to check the students’ understanding
through discussion, practice questions or providing real objects that students would
measure and then calculate the surface area. It may be worthwhile to investigate
student understanding of surface area. For example, some students may know it as
the application of a formula and others may understand that surface area can be
determined by combining the areas of all individual faces.
Review Idea: To review surface area of rectangular prism, have students calculate
the surface area of the box they created (See Lesson 2).
Importance of Surface Area
It may be worthwhile to facilitate a discussion around the meaningful applications of
surface area. Discussion topics may include:

What fascinates artists, mathematicians and designers about the beauty of
shapes?

What is the importance of basic figures?
Some examples of real world connections are: sod, wrapping paper, paint, wall paper,
flooring, sculpting, etc.
Surface Area of Pyramids, Cones and Spheres
Once all students seem to have arrived at similar understandings, have them apply
this knowledge to pyramids, cones and spheres. Using a net approach will be easy
for a pyramid. For a cone you would need to show  rs as the formula for calculating
the area of the sector. With a sphere, you can use an orange. Take the peelings and
piece it together making 4 circles that have the same radius as the radius of the
orange. For teacher reference see video: Surface Area of a Sphere
Missing Dimensions
After students have practiced determining surface area you would then need to give
them a surface area and ask them to determine a given dimension.

Going Beyond
Have students discover/prove why  rs can be used to determine the area of the
sector which is the side of the cone.

3-D MYSTERY MODEL ACTIVITY
Revised and used with permission from Bryan Quinn.
You will need one Pyramid A and four Pyramid Bs to complete this activity. Use the
nets given to cut out and make the five pyramids from cardstock (or paper). Cut on
solid lines and fold on the dotted lines and put glue on the tabs (or tape edges).
1. Without taping the pyramids together, arrange your 5 pyramids to make three
congruent pyramids in a row, as shown below.
2 Pyramid Bs
Pyramid A
2 Pyramid Bs
2. Start with your answer to #1 and tape together the five pyramids in such a way
that the taped edges act as hinges, so that the pieces of the 3-D model above
can be “folded up” to form a square prism
3. State the geometric property relating the volume of pyramids and prisms
demonstrated by this model. Can we extend this property to other volume of
prisms formulas?
