Interactive worksheets -- my newest passion.Students enter answers in cells. If they enter the right answer, the cell turns green. If they enter the wrong answer, the cell turns red. Instant feedback. I love it. I use them in conjunction with Google Classroom, so I can make a copy for each student.The problems are images, and I couldn't get them to line up perfectly, so if you like things to be just so, you may not want this one. It's not terrible, or I wouldn't use it. :)This file only h
