    Hi Adrienne,
    I’ll use this recording sheet and it pretty much lays the structure out for how I’ll conduct these tasks.
    Whenever I do this with 5th grade students I’ll let them use a calculator because there is a lot of application going on. My thought is if students don’t know what they are doing the calculator won’t help them. We’ll normally do this as a grade level team during collaboration before students ever see it. It really prepares us for the type of questions and solutions paths that students can possibly take.
    If you’re departmentalized, maybe give it a whirl in a vertical team. The conversations with teachers have proven far more powerful than me just sitting and grinding through a task…which I’m sure you agree. Let me know how it goes and if I can help out in any way just holler.
