and place them on the continuum, which shows you where to start them with their sorts. You should not need to worry about them not doing the sorts previous to their level, as their placement test showed you that they have a pretty reasonable mastery of the easier sorts. We don't want children continuing to practice what they already know. Go ahead and start them where they land on the continuum. Consider having them do all the sorts in say, Letter Name/Alphabetic before moving them up to the next level.
