With that said, I'll mention there was a different author for the primary grades and I found the curriculum to be learner centered, developmentally appropriate, and based on comprehensible input. My students were very successful and best of all - this was the MOST teacher friendly math adoption I've ever used.

Critics will mention that it is a bit weak on problem solving but that's easy enough to extend in class and I've never encountered a curriculum that was perfect at everything, lol! If I had a chance to teach this again, I'd do it in a heartbeat.
