Chicka Chicka Boom Boom, free stuff for your classroom! I love starting the school year with the classic book, Chicka Chiicka Boom Boom! It's so well known that most of the kids know it by heart and it's a great way to establish the attitude that we are all readers. I'm working on a packet of math and literacy centers because I think that using a favorite book to introduce center routines and expectations is a good hook. Today's freebie is one of the activities I've created to use for my first math center. Click below the picture to download this activity. Happy 4th of July!
