I do not, but I just looked it up, and it appears to be a language- and discovery-heavy constructivist curriculum like Everday Math. If your child was successful in EM, then she will probably do fine in CM. It has the same spiral structure, so she'll probably have additional exposures to anything skipped in intervening grades. It seems that EM and CM are often paired, because of their similar philosophy.
