I have a fairly high functioning Autistic student with Marfsans Syndrome whom I thought could count money, well he can count paper money and pennies, but when we come to other coins he cannot get it, he can tell you a nickle is 5 cents or a dime is 10 cents thand that is equivalent to 5 or 10 pennies, but when I give him 2 nickles and lay out 10 pennies on top he can tell me that those 2 nickles equal 10 cents but when I go back and ask him what a nickle equals he then says 10 cents. Then he starts getting frustrated because I think he wants to know how to do it, and he is fine if I give him nothing but pennies. Any suggestions, on another way to teach this, OH BTW, he can tell you 2 $5 bills is $10 or 3 is $15 and then a $5 is 5 dollars so he understands it with paper, or else just that much I did not try him over 3 5's. I just need a website or another way to teach him that would help, I tried the calculator, counting change with 5 pennies over each nickle and even some worksheets which did not help. I need another alternative to try on Monday morning before we both cry!
