The C&C guides are useful for a wide range of age groups. Instead of labeling them with a specific grade level, maybe use a range of topic complexity (like intermediate - advanced).
I have been thinking about the curriculum guides in a similar way. One example is the sorting and classifying lesson...
In science there are a lot of classification schemes to understand... The Five Kingdoms (or Three Domains). rock types, space objects, or cloud types. I was thinking about helping kids understand classification systems by coding them on buttons. Think Buttons.
For instance: imagine a set of buttons with the names of organisms on them:
elephant daffodil yeast euglena spirochete
The elephant, daffodil, yeast and euglena might all be buttons that have 4 holes in them because they are all eukayotes, the spirochete might have a shank because it is a prokayote. The daffodil and euglena might both be round buttons because they are both photosynthetic and the elephant, yeast and spirochete might be square buttons... The yeast and the spirochete might be printed on yellow buttons because they are single cells and the others printed on red buttons because they are multicellular.
Rock buttons be sorted into igneous, metamophic and sedimentary, felsic and mafic, biogenic or abiogenic,hardness
Space objects might be sorted into manmade, natural, size, compositon.
I haven't thought this all the way through. But, I really like the idea of the curriculum and construction guides demonstrating that the skill can be used at different levels of sophistication. Sorting and classifying stays the same... whether you are working with shapes or textures or archaebacteria and eubacteria. Since the thinking skills are not confined to a grade level, it would be interesting for a curriculum guide not to be confined to one as well.
