Hands-on investigation for learning how to understand time. A large felt circle with smaller incremental circles/squares (hour, minutes) with 5-10-15-... would make an awesome time clock. Hour circles different color than minute circles. I would place the minutes in circles, hours in squares (or vice-versa) for easy differentiation. Lego's make up the 5 minute bars.
