Identify and Trace Numbers 11-20 0-103

Model teen numbers as 10 and some more. 11 is 10 and 1. 12 is 10 and 2. The names for 11, 12, 13, and 15 can be confusing because they don't follow the pattern. Nicknames like "1 ten 1" for "eleven" and "1 ten 2" for "twelve" can help make sense of numbers and lay the foundation for place value. Practice writing by tracing.
