We’ve been practicing mental arithmetic with the help of some old gaming dice.
D4 D6 D8 D10 D12 & D20.
Roll somewhere between 1 & 3 Blue Dice (D8 ,D10 & D20 Range 3-38) which are our additions and one or two Red Dice (D6 & D8 – Range 2-14) which are our subtractions.
This gives us a very quick way to throw lots of random numbers where we can dynamically change the complexity or ranges just by adding or changing the dice size or numbers.
We have also started using a 1xD4 & 1XD20 for small multiplications.
