We have just begun adding and subtracting decimals to thousandths (for example one rial three hundred and ten baisa is written as 1(whole number). 3 (tenths) 1 (hundredths) 0 (thousandths). To refresh our memories of place values we began with a decimals dice game. In the first round children had to roll a dice and make the biggest number possible and in the second they had to make the smallest one possible.
