These (Google Slides) multiplication flash cards have a transparent box on the top of each slide. If you would like to add your own bitmoji (or do any other edits), you will need to move the transparent boxes, add your bitmoji, redo the links, and then replace the transparent boxes on top of the slides. The students should view these flash cards with the following code: preview?rm=minimal. To do this, just get a sharable link and replace everything through the word edit and replace it with the code. This way, the students will not be able to skip slides.
