Activity 1 (pencils and paper):
a simple picture
is to be copied
into an oblique parallelogram.
Activity 2 : my software lets students put different values in a transform matrix and instantly see the effect. They try to find the correct matrices for a variety of given transformations.
3.
[T5] is the matrix for translating (sliding)
2 units to the right. Use the calculator to
work out [T5]10 and [T5]50
and write them down.
What transformations would these represent?
What do you think [T5]500 would be?
Activity 3 : Students complete a worksheet on various aspects of matrix multiplication, exponentiation and commutativity. They use both computation with graphics calculators and their new-found geometric interpretations.
