I found this activity on Activities of Downstream Parenting. We started with the book "I'm the Biggest Thing in the Ocean". I wrote all the words out, and then we laid the notecards out on the floor. We used them like a matching game with the words in the book. It was a big hit.
Hanna then grabbed a new book the next day and began working on note cards for each word in the book. She did a great job, had a lot of fun and stayed busy for quite a long time!
