After a year of working with the Golden Bead materials, I introduced DJ to the Stamp Game this week. This material will be used in a very similar way to the Golden Beads to do addition, subtraction, multiplication and division. However, instead of have a tiny unit bead and a large thousand cube, each category will be represented with a small square with the category written on it. This is the beginning of the "passage to abstraction" - although DJ will still be working with concrete materials, they are more abstract in that there are not size differences.
