First Grade Schoolhouse: What is Your Prediction? Do Not Open This Book! by Joy Cowley is a wonderful big book to promote the love of reading. It can be used to introduce making predictions and works well for shared reading.
Llama, Llama Red Pajama [Book] -- my 2 youngest and I fell in love with this the first time we heard it read at library story time. Also: Llama Llama Mad at Mama; Llama Llama Misses Mama are a few others we enjoy.
