Excellent. Nice task to close off an introduction to the topic once a class have had a go at a few typical questions. This definitely stops it from getting too repetitive in an hour lesson - great for the second half of the lesson.

Lots of practise at putting together a two-way table from a set of information. I will admit to being a bit sceptical that the coffee spilling is a genuine scenario ;-) <br /> I like the idea of students creating their own puzzles for the sixth form years too!

Not the usual tedious tables - a bit more interesting. My year 7 loved them. I extended the task by asking the pupils to make up their own puzzles for staff/6th form - to see how few clues were necessary.

Nice way of looking at 2 way tables and getting pupils to create them from scratch - thanks for this!
