The fabulous Five Card trick The Five Card Trick As presented here, this trick encourages use of the 5x table for younger kids. You could make different versions, e.g. the "seven" card trick would familiarise kids with the seven times table and for this the cards would need to be numbered 1-7 and 8-14.
