Red Chief's kindergarten teacher mentioned that he could use some practice with his numbers 11-20. I searched the web for some practice worksheets, but most of what I found was for numbers 1-10.
So I made him a practice packet myself, covering numbers 1-20. He's learning them so fast that I don't think we'll have to use all of it, but I hope others might find it helpful.
