Over the summer I recommend that PLC members study this chart by Marianne Van Klaveren, which is an expanded version of the original Star Sequence I developed last summer (2017). It is not linear in nature, but describes a curriculum in spatial terms. This is needed because of the spatial/unconscious way humans learn languages. Teacher’s Discovery is considering making it into a poster.
