This is just an idea I had for another use for the 700+ fraction diagrams I made for my fractions worksheets. (these diagrams are available to download) I have not tried these worksheets out yet but I foresee that students will have to be quite meticulous to complete them but might also pick up a few things about fractions as well. I hope they will realise that when doing question 4 that it becomes easier if they turn the sheet so the line of reflection is vertical.
