Four lots of 4 average and range problems where the students are given the answer but need to find the blanks in the question. Some have one possible solution and some have many solutions which automatically builds in differentiation as you could task students with finding the range of possible solutions. I use these as starters/plenaries but use them however you like (assuming you like them).
