This is just a really basic board, set up with pronouns on the left, then verbs, then adjectives/adverbs, then nouns. In short, it's set up to help make sentences. There's a version that's mostly filled in (although all of the nouns except bathroom are editable and you can replace them with what you want) and a version with the exact same layout which you can add additional words of your choice. The first one is a really pared down version and the second has more buttons but preserves motor planning because all the core words are in the same space.
As usual the thumbnails are weird, the formatting is fine once you open the doc.
