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."</p></mdoxml> 0 0 0 0 0 0 0 Postcards NRICH Postcard designs, available to print out or order.
