Secondary 1 - Number and Algebra

Standard 7.NA.4 - Determine the constant of variation from a word problem and a table.

Included Skills:

Rate and Speed
• 4.1 relationships between distance, time and speed
• 4.2 writing speed in different units (e.g. km/h, m/min, m/s and cm/s)
• 4.3 concepts of average rate, speed, constant speed and average speed
• 4.4 conversion of units (e.g. km/h to m/s)
• 4.5 calculation of speed, distance or time given the other two quantities
• 4.6 problems involving rate and speed
• 4.7 Discuss examples of rates e.g. currency exchange rates, interest rates, tax rates, rate of rotation and speed.
• 4.8 Find out and compare the speeds of bicycles, cars, trains, aeroplanes and spaceships and their respective units to have a sense of their magnitude.
• 4.9 Explain the difference between average speed and constant speed and also explain why average speed is not the average of speeds.
