This activity is interactive using Google Slides. It allows children to add and subtract by dragging the pepperoni onto the pizza to add how many are all together, and also taking away the pepperoni off the pizza to subtract and count how many are left over. Finally there is a fun activity to create your own pizza with however many pepperoni you choose! *Make sure you "make a copy" first for yourself in Google Slides and also click on "make a copy for each student" when uploading it to your Google Classroom.
