I adapted the concept to make "Word Doors." Each week we pick a topic and decorated the top portion of the door with it somehow. Then I read a few books from that topic to the girls. Whenever they hear a word they like or don't know they stop and tell me. I write the word on a half-index card, which they decorate with a sticker and tape onto the door.
When we are done, we read all the words together. Then about once every other day we review all the new words (not all are new) which are on the door. This exercise greatly enhances their listening skills, as they both want to pick the best words from the book.
They also love making the Word Doors and want to show Robby the new Word Doors as soon as he gets home.
When we did a Fancy Nancy door, the girls started out by dressing up as fancy as they could first:
It has taken Sabrina a few weeks to consistently hang the words right side up. Here's a close up of part of our Curious George door. I am always impressed at how many words the girls choose.
