This file includes chant posters for the tricky teens (11-20). Another teacher gave me the chants then I created fun posters to hang in the classroom. I spent a few days introducing each chant then we started doing the chants as part of our morning calendar time. It only takes about 1 minute to run through all of them once the kids learn them. Included in the file suggestions of motions to do with each chant. These chants helped my students learn to recognize their teen numbers very quickly! They really work!
