It is very common (and developmentally appropriate) for kindergartners to reverse their numbers. However, it does become a problem when they reverse the order when writing teen numbers (i.e. writing 31 for 13). Below are some songs I play to help with that!
It is important for students to become comfortable with whole numbers 11-19 and to understand that these numbers are composed of a ten and some ones. In kindergarten, we are laying the foundation for understanding place value and the base-ten system by drawing special attention to 10 as a landmark number through hands-on activities and exploration.
