Better late than never! I compiled some computational thinking puzzles into a booklet for KS3 to take home for Christmas. With the Y11 Mocks intervening in January, I didn’t get round to prize-giving until just this week. After sharing the winners on my school Twitter feed I’ve had some requests for the booklet.
Here it is, shared CC-BY-SA as usual, most of the contents are from cs4fn.org and shared with permission.
Both question and answer booklet are on my CAS resources page (some of my students have found this page so there will be no answers here).
