In my classroom, I will not be organizing the books by reading level. Instead, I want to organize them by topic/author. Organizing them that way encourages children to choose books based on what they are interested in, not ability.
The Chicka Chicka Boom Boom Tree is made from a carpet roll (free from local carpet store) tube wrapped in brown butcher paper, stuck in a Christmas tree stand. The top is an umbrella covered with green leaves.
