Although born and bred for rugby, Powys school improvement officer Maldwyn Pryse has created a set of free online learning materials for the World Cup. So make the most of the motivation potential before the competition finishes (you can also try out the Powys team's free website-building technology).
A search on Google yields a wealth of World Cup material, but Maldwyn's bilingual contributions allow you to use spreadsheets and project ideas for upper key stage 2 and key stage 3 in Welsh. The faint-hearted can visit the Powys team's website, click on English, and then Documents and Categories before choosing 2006 World Cup. Click on Cymraeg for a walk on the wild side.
