Each Google Slide has 2 sets of items (same 2 images) with 3 choices of numerical ratios to choose from at the bottom of each slide. The background is set. There are two types of choice markers to choose from. Students can use a manipulative clothespin to mark the answer or they can use the set that has a large red circle to select their answer. Lessons can be used for virtual learning or with an interactive smartboard for face to face instruction. Slides can be moved around to change the order.
