### Clock Hands

This investigation explores using different shapes as the hands of the clock. What things occur as the the hands move.

### Transformation Tease

What are the coordinates of this shape after it has been transformed in the ways described? Compare these with the original coordinates. What do you notice about the numbers?

### Penta Play

A shape and space game for 2,3 or 4 players. Be the last person to be able to place a pentomino piece on the playing board. Play with card, or on the computer.

# Flip

##### Stage: 2 Challenge Level:

I'd like you to imagine a large square piece of rigid plastic, maybe perspex or pretend glass.
On it is marked a square made up of 6 x 6, that is 36, dots:

Someone marks a capital or big "F" in this way:

You are pretending to hold this in front of you.

You are going to flip it over in front of you along imaginary lines which I've drawn in blue on the diagrams below. You could do this by imagining you are holding each end of the blue line with a hand and turning the sheet over.

Each time start with the "F" as shown above, and in your mind find how it will look when you flip it along the blue line.

First this one:

Try to describe to someone how it will now look to you.

Now try this one:

If you feel you could go further try this one:

And my last suggestion as a different way of flipping is:

How did you get on?

Talk to others about the experience.

If that's been ok. then use this next shape instead of the "F" and do the same flips.

Can you tell where the triangle will be?
