The PDF file is designed to be a self-correcting addition station. This is a fun, unique, and self-correcting station for reinforcing and reviewing sums to 20. This file includes SUMS for 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20. There is also a color and black and white version. My students can’t wait to finish their work so they can get into this station. I make multiple copies of each fact so my students can race each other to see who can finish same facts first. I have noticed a big difference in my students’ automaticity and fact cognizance.
