DO NOT USE CALCULATORS FOR THIS WHOLE CLASS ACTIVITY.
YOU NEED TO KNOW: that the cosine and sine functions for ALL ANGLES are given by the coordinates of points on the UNIT CIRCLE. The x-coordinates of points on the unit circle give the cosine of the angle between the x-axis and the radius measured anti-clockwise […]
How could I make graph 2 from graph 1? Can you work out the equation of graph 2?
Graph 3 has equation y=sin2x. […]
When would you be turning the steering wheel to the right?
When would you be turning the steering wheel […]
Comparing investments: there are six investments. Find all the representations (description, formula, graph and table of values) of a single investment. After this, work out which statement fits with which investment.
The teacher leads a very short discussion about the different types of investments, reminding the learners about simple and compound interest. He or […]
This lesson is about moving between different representations of distance-time functions, namely between graphs, stories and tables. This activity should be given to the class as a formative assessment activity: it is designed to provide the teacher with information about the learners’ current levels of understanding.
During a short introduction the teacher displays a […]

The graph shows the distance along a race track for two racing cars as they approach a bend in a race. Copy the table below, take readings from the graph and fill in the table for the first 10 seconds.
How far does each car go in the 3rd second? How far […]
Make boxes with different volumes by varying the sizes of the squares that you cut […]
(i) Write down the coordinates (0; c) of the point of intersection of the line with the y-axis (the y intercept).
(ii) Choose two points on the line . […]
