It is expected that students
will determine measurements in Systeme International (SI) and Imperial systems
using different measuring devices
It is expected that students
will:
select and use appropriate
measuring devices and measurement units in Imperial or SI systems
perform basic conversions
within and between the Imperial and SI systems, using technology as appropriate
use measurement strategies
to solve problems
SUGGESTED
INSTRUCTIONAL STRATEGIES
Real-world activities involving
measuring, converting between systems, and estimating enable students to explore,
describe, and manipulate the physical world around them.
Divide the class into
small groups and provide students with a variety of measuring instruments
(e.g., calipers, micrometers, scales, metre-sticks, measuring tapes, trundle
wheels). Assign objects to be measured to each group and have students report
to the class their choice of measuring device, the ease or difficulty of measurement,
and the precision of the resulting measurement.
Use models and manipulatives
to demonstrate the multiplication of units in two and three dimensions .
Have students research relationships in the metric system .
Have students create
posters that display conversion factors or simple instructions for conversions
between Imperial measures and corresponding SI measures, and vice versa. Compile
the posters into a large book for classroom use, or display individual posters
in a hall display. Have students use the posters to practice conversion problems.
Have students measure
the diameter of a round table in metres. Have them convert the distance to
feet, then measure again in feet to check their work.
SUGGESTED
ASSESSMENT STRATEGIES
Measurement experiences
are a powerful application of mathematical theory to everyday phenomena. Students
demonstrate their knowledge of measurement concepts by generalizing about strategies
and performing basic conversions.
Observe
While students are working
on measurement activities, circulate and provide feedback on:
their abilities
to use the correct measuring devices and measurement units
the extent to which
they consider the reasonableness of their answers
their overall understanding
of measurement concepts in solving problems
Collect
Review students’ written
work in using measurement technology for evidence that they can:
give a situation
in which using one particular measuring device is preferable to another
give examples of
situations in which a most appropriate device for measurement exists
change units of linear
measure from SI to Imperial and vice versa
Have students research
the history or development of a particular unit of measure.
Self Assessment
Ask students to keep
journals to describe the processes they used in dealing with problems. Have
them include descriptions of strategies that worked, and those that did not.
Have students keep a journal or scrapbook on the advantages of the SI system
over the Imperial system.
Peer Assessment
Have students check
each other’s work using appropriate measuring systems.
RECOMMENDED
LEARNING RESOURCES
Comprehensive learning resources
for this course are currently under development. As an interim measure, schools
are encouraged to use the teacher-developed learning resources distributed to
schools (student and teacher resources). Please note that the student materials
require photocopying for student use.
