We also have five postcards we are no longer printing, but by clicking on the links below you can print them for yourself.
Mrs Melrose, a teacher st St Leonard's Primary, East Kilbride got in touch with us to explain how she used the postcards:
"I am writing to thank you for the class sets of free postcards you sent me. I decided to send them home as a homework task. The children loved the idea of maths homework being presented in this new, fun format and were keen to show me their solutions the following morning. Many now access the NRICH website at home and enjoy the challenging online interactive problems. I will be using these
postcards again to continue stimulating interest in problem solving at home."
