This is meant to be a resource for 1st graders to help them with their writing. It is somewhat of a portable word wall. Most first grade site words and common words are listed and their is room for other words to be added as needed with the writing. There are also other resource pages such as shapes and money.
I always had my kids open to the correct page and raise their hand when they needed a word spelled that was not on the word wall. This worked great even during my writer's workshop time.
