Help! I have always had kiddos who have difficulty counting and writing the numbers 11-19 because they don't sound the same as most of the following numbers. However, this year, I have at least 1/3 of my class that I am not reaching. I need new strategies for counting and writing numbers (in sequence and in isolation) for 11-19. I would love your ideas or even links to printables, file folder games, worksheets, flash cards, etc. Anything you can share would be helpful!
