Rotation Challenges

Years 2 - 6

Glenda Pain, Port Wakefield Primary School as part of a Maths on the Move program titled Engineering 'aha' Moments in Number

Procedure

Stack the red board on top of the blue/yellow, press out the centre plugs.
Put them into the boards again to make an axle.
Rotation Challenge 1a
Then press out the three corners as shown.
Now predict what you will see if the red board is rotated ¼ Turn (90°) anti-clockwise.

No peeking now until you have thought about it.
But if you have...
Rotation Challenge 1b
and another ¼ Turn (90°) anti-clockwise?
Rotation Challenge 1c
and another ¼ Turn (90°) anti-clockwise?
Rotation Challenge 1d
and another ¼ Turn (90°) anti-clockwise?
Rotation Challenge 1e
Not too difficult perhaps...
but predict what you will see if this pattern is rotated ¼ Turn (90°) anti-clockwise.
