Included in each teacher packet is an evaluation form for teachers to return to ACF. Here is a selection of comments from the evaluation forms about ACF’s materials: 

"I am so excited to find your website! ...So many web sites are just a waste of time. Yours, however, is the best I have ever seen. Thank you for such good, usable information in one place as well as the hands on activities. I have copied your chocolate chip cookie activity to show them how much fun it can be to really learn. I have clearly given your site full credit for all the information and also listed your teacher's store as a resource for us. Thank you again for such a great resource."
Brenda Runkle, Brink Junior High School, Moore, Oklahoma
