This week we are celebrating puzzle number 100! And boy is it a doozy. A really nice logic puzzle, relating to something very close to our daily lives - timetables. You have to decipher the clues about Kayleigh's timetable in order to figure out how many students are in Mr Thompson's class.

It's going to be a great achievement for you to get this one out as it does require some deeper thinking.I've attached a logic grid and empty timetable for you if you need the structure.

I know that we've had a busy assessment period, but now that it's done I'm hoping that you try to attempt the puzzle and don't just give up because it gets hard. I will be giving merits to any student who attempts the puzzle this week and submits an answer.

Good Luck and Keep Puzzling!
Mr Withnall
