Lesson 1.13
In this lesson we explore how to develop the the equations for a system from a word problem. Success criteria for this lesson will include associating words with mathematical operations and deciding what might be the best method, substitution or elimination, to ultimately solve the problem.
Lesson 1.14
In this lesson we look at our first style of application question that we can fully solve. Finding two numbers given some conditions, and the ages of two people given some set of conditions.
Lesson 1.15
In this lesson we look at problems involving distance, speed and time. We will pull on student knowledge of speed being measured in kilometres per hour (km/h) to remember that speed = distance (km) divided by time (h).
We will also explore questions involving planes flying into and down wind, and the effect that has when developing the equations.
