'Knight's Swap' printed from http://nrich.maths.org/
Why do this
requires children to make use of visualisation and
to develop their own methods of recording.
Do you know how a knight moves in chess?
What could you try first?
How will you record the moves?
Suggest to learners that you can now put the two stars on the
board anywhere except the middle square. Can they find a way to put
them on so that it is impossible to switch the pieces? Can they
give a really clear explanation?
Pupils might like to draw a square and use some counters to
help them see the moves.
