Thanks for asking! Please do use our activities and worksheets in our classroom. If you are reprinting worksheets for classroom use, we just ask that you maintain all attributions on the worksheets (and activities, if you're printing them out). So, as long as you keep the title, content, and Education.com logo in place, you're free to make copies as you wish! The best way to do so is to use the on-screen print function, and then to make as many copies as you need.
Let us know if you have any further questions by contacting email@example.com
