Workplace and Apprenticeship Mathematics 10

	It is intended that students explore, analyze for patterns, and develop understanding of many units in all three systems of measurements. The units used should be those that are appropriate to the workplace or apprenticeship context being considered. These units include: metres, grams, litres, and seconds along with appropriate prefixes such as kilo, hecto, deci, centi, and milli, as well as hectare, tonne, and degrees Celsius (SI system). inch, foot, board foot, yard, mile, acre, teaspoon, tablespoon, cup, pint, quart, gallon, bushel, ton, and degrees Fahrenheit (British and US systems where appropriate).
(a)	Research and present about a topic related to measurement systems such as: how the SI system and the Imperial system were developed the adoption of the SI system in Canada development of the US customary system and the relationship between the units of this system and those of the Imperial measurement system (e.g., units for length and area are the same; there are differences, however, for mass, weight, and capacity) early systems of measurement in Canada and contexts in which some are still used today (e.g., hand span and thumbs for measuring horses from the ground to its withers).
(b)	Describe situations relevant to self, family, or community in which the SI and/or Imperial systems are used.
(c)	Analyze the relationships between: the base units of the metric system of measurement and the base ten number system the prefixes used in the metric system and powers of ten the related units for length, area, volume, capacity, mass, and temperature for each of the two systems of measurement.
(d)	Explain, using examples, how and why: decimal numbers are usually used for SI units fractions are usually used for Imperial units.
(e)	Provide an approximate measurement in: SI units for a measure given in Imperial units (e.g., 1 inch is approximately 2.5 cm, 1 kg is a little more than 2 lbs) Imperial units for a measurement given in SI units (e.g., 1 litre is approximately 1/4 US gallon, 250 mL is approximately 1 cup).
(f)	Develop (using proportional reasoning), generalize, explain, and apply strategies (including formulas) to convert measurements from: SI to Imperial units (e.g., Celsius to Fahrenheit, centimetres to inches, kilograms to pounds, litres to quarts) Imperial to SI units (e.g., Fahrenheit to Celsius, inches to centimetres, pounds to kilograms, quarts to litres).
