Thank you

Thank you so much for not providing answer keys online, but teacher notes that provide enough information to create one. I have had numerous students immediately search for that I want them to complete to see if an answer key has been uploaded. My colleagues and I are grateful for the hours you have spent creating and refining these wonderful activities.
