Great question! Unfortunately, we do not currently have answer sheets for all worksheets on Education.com. Due to valuable feedback (from members like yourself!) about how helpful answer keys would be, a few months ago, we began asking worksheet designers to include answer sheets for all worksheets for 3rd grade and above - as well as all puzzles.
For all worksheets that include answer sheets, you can download the answers by clicking "View Answer Sheet" under the worksheet's image.
That's probably more background than you need, but wanted you to have the full story. Thanks so much for the feedback!
