Last year, I used the Ocean worksheets to prep my kids on vocabulary before we went to a play about the ocean last year. Here are some of my favorite worksheets from that pack.

Here are the flashcards for camping vocabulary (they have these for pretty much all thematic packets)
Here is a cute sorting task.
And more tracing worksheets based on the vocabulary.
