The names and values of Canadian currency
| cent, penny, copper 100 cents = 1 dollar 1 cent = $0.01 |
| nickel, 5 cents 20 nickels = 1 dollar 1 nickel =
$0.05 |
| dime, 10 cents 10 dimes = 1 dollar 1 dime = $0.10 |
| quarter, 25 cents 4 quarters = 1 dollar 1 quarter = $0.25 |
| loonie, 1 dollar 1 loonie = $1 or $1.00 |
| twoonie, 2 dollars 1 twoonie = $2 or $2.00 |
| As Canada becomes more metric and is becoming ready to drop the period
"." as a decimal point, it is becoming more common to see money being
written in 2 ways. The English side of price tags usually still read
something like $39.85 while the French side of a price tag will read
39,85$ |
Although Canada went metric in 1970, students in grade 4 still seem to think
in feet & inches when it comes to certain things like their height.. This
cartoon from You're on Your Own, Snoopy by Charles Schulz 1971
is almost as true today as it was then. For information on our metric
conversion, visit One

Linear Measurement Facts
| 10 mm = 1 cm |
| 1000 mm = 1 m |
| 10 cm = 1 dm |
| 100 cm = 1 m |
| 10 dm = 1 m |
| 1000 = 1 km |
| a student ruler is 30 cm |
| width of a fingernail is about 1 cm |
| width of a door is about 1 m |
| height of a door is about 2 m |
| it takes about 10 minutes to walk a km |
| hardly anything in the real world is measured in dm |
Abbreviations
| millimetre = mm |
| centimetre = cm |
| decimetre = dm |
| metre = m |
| kilometre = km |
| perimeter is the distance around the outside of an object that is 2
dimensional, namely flat |
| the 2 dimensions of a polygon are usually referred to as length and width
or height and width |
| area is the surface, measure in squared units, of a flat object |
| students need to be able to calculate the area of regular triangles and
quadrilaterals and estimate the areas of irregular figures (2 dimensional or
flat closed shapes) |
| The easiest way to start to think of metric is to know some physical
examples of metric units as benchmarks. |
| Rather than converting from feet, pounds, or gallons, learn some examples
of metres, kilograms, and litres. |
| Linear Measurement Examples
 | 1 mm The thickness of a dime (10 cent). |
| 1 cm Diameter of a AAA battery, or the length of a thumb-tack. |
