Circumference and Area of a Circle

I used @_rhi_rhi PRET homework on area and circumference with my low attaining group. Many of them just gave answers and a lot of the answers were incorrect. It was frustrating that I needed to interpret the answers in order to work our what they had attempted to do.

After spending time looking at PixLs ‘thinking hard’ materials in our schools last extended, I thought I’d use an idea I had shared when giving students feedback. Instead of marking, correcting or even getting students to correct errors. You just tell them how many errors were made and ask them to find them

So the task below is the 8 questions from the PRET homework with 8 answers but only one is correct. Students are to find that answer and assign feedback to the other 7. Some feedback can be used more than once.
