I've seen the teaching hands clock around before and I thought I would highlight it here today. The teaching hands clock has a unique (patent-pending) design that cues students to look at the correct hour and minutes. In particular it is useful for learners who consistently give the wrong hour between :30 and :00 (which is the error I certainly have seen most as far as time telling).
It is costs about thirty dollars from A Different Road to Learning, Autism Shop or the links below.
The clock is also available with a magnetic teaching kit for $40.00 about from Silverlining Multi Media and Nasco School Supplies. The teaching kit alone is about $20.00.
This might be a great item to add to your end-of-the-year purchase orders.
