This was a nice review of the of the program components, but I would have liked more examples and explanation for place value. Dr. Flores talked about paring Add 0-9 and Subtraction 0-9 - going through Concrete stages for each then doing Representational for each (back to back) and the Abstract. In the past, I've advised teachers to teacher all the of addition before going to subtraction, so it will be interesting to see how this sequence works.
