Numbers in the Teens (They Start with a 1) This song was written because I was frustrated with students getting their "teen" numbers mixed up. For example, many kids were writing "61" instead of 16, etc... This song contains a catchy chorus to remember that all teen number start with a 1. It then goes into naming each teen number and identifying the two digits that make that number. This song is to help students with "how to write" the teen numbers. Please see my place value version to help with "groups of tens" and "groups of ones."
