Miss M has long had a fascination with rocks. Everyone once in a while, she will find a special rocks and declare it to be a "dictionary rock" and proceed to tell us all the wonderful things written on it.
We have been working on sight words and CVC words for a bit, and Miss M has finally learned enough words for reading simple sentences. So, I took some rocks and wrote her words on them with a permanent marker - making real "dictionary rocks".
Miss M has been reading her rocks in the sandbox and loving them!
She has about a dozen so far, and I plan to keep adding words as she learns them as a sort of outdoor word wall.
