Drawing a triangle is not always as easy as you might think!
When I park my car in Mathstown, there are two car parks to choose from. Can you help me to decide which one to use?
Can you find sets of sloping lines that enclose a square?
Which is bigger, n+10 or 2n+3? Can you find a good method of answering similar questions?
Can you make sense of the three methods to work out the area of the kite in the square?

In abstract and computer generated art, a real object can be represented by a simplified set of lines. Can you create a picture using mathematical instructions?
Investigate what happens to the equation of different lines when you translate them. Try to predict what will happen. Explain your findings.
I took the graph y=4x+7 and performed four transformations. Can you find the order in which I could have carried out the transformations?
How does the position of the line affect the equation of the line? What can you say about the equations of parallel lines?
