NUMBER TRICKS
The Massive Number Prediction A trick where the volunteer adds five huge numbers, but you have written the answer down even before you know what the numbers are! The 71113 trick A trick multiplication you can do faster than a calculator The Prime Numbers Trick A strange little prediction A betting trick with seven cards that always makes money! The Red and Black Mystery! A card trick to baffle people, and you don't even need to touch the cards! The Mindreader A prediction trick. (Hint: it relies on the properties of the number nine!) 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 17 and 814.
The Fibonacci Trick A nice little prediction which involves a Fibonacci series. Finger Times Tables How to multiply up to 10x10 with your fingers. The 1089 Trick and some 1089 facts!
