Synchronised Pythagoras

Synchronised Pythagoras

Your roamer is part of a synchronised swimming team.You will need to use directional instructions as well as estimation skills to get as close as possible to the centre of the target.

You have 15 minutes to devise a short programme to key into the roamer and to practise.

Note: The roamer gets a little dizzy when turning through large angles. When it gets dizzy it can wander off track. Bad news for any synchronised swimmer!

Start here on

the target, facing the

skittle

Skittle Ball

•Complete programme sheet (10 points)

•Knock over skittle (10 points)

•Pirouette (5 points)

•Kick the ball (10 points)

•Pirouette (5 points)

•Land on target (up to 10 points)

You get more points for being on target!!!

If your roamer strays out of its area it will be removed from the competition.
