I’m going to assume you mean Children’s Picture books.
1. Don’t Let the Pigeon Drive the Bus by Mo Willems - This is my favorite series to do read alouds with. They are a hit every year and really excite the kids about listening to books — often better than some of our weekly books.
2. It’s Okay to Make Mistakes by Todd Parr - toddparr is one of my favorite Children’s authors. His pictures are colorful and I think subtly tell children that you don’t have to be able to draw things exactly right and they always have a good message. This particular book is helpful for students that are afraid to try/fail and kids that get really upset when they make a mistake. Such a great conversation starter.
3. Chicka Chicka Boom Boom by Bill Martin - The book has a good rhythm and the kids love to chant it. It is excellent for introducing upper and lower case letters. The secret sneaking off to the top of the coconut tree is a little bit of an adventure that gets kids excited.
4. There’s a Monster at the End of This Book by Mark Smollin - another great book to do as a read aloud with voices. The kids laugh so much and will ask to hear it again and again. Someone donated this to my classroom this year!
5. Where the Wild Things Are by Maurice Sendack for obvious reasons
6. Imogene’s Antlers by David Small - This was my favorite book as a kid and I memorized it and took it to class and told everyone I could read.
I would recommend any of these for gifts to young children or to prek-1st grade teachers.
