Estimating the mean from a grouped frequency table

Download the resource here

Starts with a little task on finding the midpoint. I often find this trips students up more than you would think.

Moves onto some example problem pairs and then a very (overly?) structured worksheet.

I don’t know how I feel about this level of scaffold. At least it reduces.

Then some questions that I wrote that I really like.

And then… that’s it. This filled the lesson nicely and I really didn’t feel like I needed much else.

Maybe I could have done a section where the mean is given but there is a hidden frequency, but I didn’t want to be overly prescriptive.
