This is my favorite new center that I've started making for my kids. There are 10 cards for the standard that I hang around the room in no particular order. The students each have a student answer sheet that they fill out while walking around the room. They HAVE to have the "task cards" in order to get their answers.
I have trouble calling these true task cards, as they are really word problems and equations, but the kids love to think of them as fun tasks. :)
I know there are several elements to this standard, so each of them is addressed at least twice.
This is great to use as practice, a center, or even a formative assessment.
There is no answer key yet. I will work on that this week as my student complete the task and then upload and update it.
