Here are twenty multiplication and division story problem task cards with QR codes so that students can check their answers!
I've used these as a math rotation for independent work. I've also used them in isolation as warm-up problems, and in workshop group! They provide great formative assessment evidence of student understanding of this standard.
When I use these, I require students to record an equation using a variable to represent the unknown and/or to model the problem. This elicits great evidence of student understanding!
