wordsearches and crosswords!
All online of course, courtesy of a superb moderated website called Bin Weevils which DS heard about and decided to try. It is a free online game for kids where they can play games including crosswords and word searches to earn Mulch (the Bin Weevils currency). This allows them to buy things to furnish and decorate their "nest" and feed their "bin pet". It's a bit like Club Penguin, except that it is completely free and the tasks are more intellectually challenging.
Of course, the benefits were immediately clear to someone who still has two more to put through the VR mill.
DD needed a bit of help but DS was only too willing to oblige with his greater knowledge and experience.
In turn I was able to help with some of the words he did not know or couldn't find. All with the motivation of building a nest for a pet bug!
All in all a very clever and stimulating little game, and a constructive way to spend a few rainy hours (is it really another week and a half until the primary schools go back???)
