Here is a Google Slides file as a follow up to the Multiplication Word Problems Matching and Creating Groups post.
Each slide has a multi-step word problem (multiplication and either addition or subtraction) that continues the use of the grouping approach. The boxes (for groups) and dots (for items) and dynamic and can be copied as needed. I suggest having an example that can be a We Do to guide the students through the use of this application. For subtraction, groups of items can be created and the dots taken away and maybe changed to red.
