I have found loop games great for developing mental maths abilities.They take away from the monotony of learning tables by heart. The children all have to co-operate in order to complete the loop/chain game. When you take note of the speed, children generally love to try and beat their best time.
This year I'm only have 6 children in my class. I made these loop cards with this class in mind. Each child will have two cards each and I will have the start card. In this way, they can practice the addition facts from +1 to +12 of any given number. If you have a class of 24 to 26 children, they can all have one card each. You could also split the class into two teams and see who can finish the loop/chain faster.
These are very simple addition cards. Previously I have made loops with 24 cards and with double digit addition, subtraction, multiplication and division for larger classes with more children.
I have double checked each card for mistakes but I'm still not confident that they are perfect. If anybody notices one, please let me know and I will update them!
