Usually, we invite students to send us their solutions to a selection of problems, but this December and January we are doing things a little differently…
The problems below contain interactivities which offer students instant feedback, and we think they are particularly suitable to work on at home, perhaps with a family member, during the holiday period. We hope you enjoy the challenges we’ve selected.
