Junior Learning JL644 Sentences Cubes, Multicolor

There are no directions to how to use these included in the package. There is a website listed for more information but I also couldn't find any guide on these there. It says color coded by parts of speech but I don't see a key. I bought these as one of the things I hoped to use with my child to teach him grammar more adequately than I was taught, I was in AP English and we "learned grammar" with some computer program diagramming sentences for about 2 weeks, but mostly anything I know, I learned in foreign language classes or intuitively absorbed "because it sounds/looks right." I didn't see any resources on Teachers Pay Teachers either for how to use these. I am sure I'll figure a way to use these eventually once I start a grammar curriculum with my child but I am rather disappointed out of the box.
