I have wondered whether buying 30 Nintendo DS would be a good idea for a daily mental maths development with Professor Kageyama’s Maths Training. I thought if there were quick mental maths questions wrapped in the alternative package of a Nintendo DS then maybe we might raise table knowledge or quick calculation. Children can also compete in groups of 15 which is also interesting. This review http://www.eurogamer.net/article.php?article_id=92874 isn’t too complimentary because it says it could have been more entertaining. Will it last just long enough to keep the children motivated until their maths improves?
I had wondered whether to give children The Hundred Cell Calculation Method on paper might do the same job for less.
