On another post I put the back story---but here's a summation. I am teaching an 18 year old moderately autistic young man. He is having trouble counting change. I have to get him to count quarters, dimes, nickles, and pennies. He knows the values of each, but he insists on counting them wrong. For example, if I show him a Quarter and 2 pennies, he will count it and 2+5+1+1=7. If you have any tips---send them my way. Math is not my forte---and I'm not sure what to do with this.
