Print the cards double sided, laminate them and cut out.
Lay the cards of the times table you want to practice with the answer side up spread on the table.
Choose a card, turn it around and solve the mutliplication on the back. Put the card on the table in front of you, with the multiplication side up to make a stack.
Then pick the answer card of this multiplication. Turn it around place the card on top of the previous card, solve the multiplication and pick up the answer card.
Do this until all cards are done. Check if you did well: turn around your stack and find the answer of the last multiplication on the back of the first card.
The magic is that it makes no difference which card you start with, if you did well, you’ll always find the answer of the last multiplication on the back of the first card.
