Painting by Estimating

All fixed! (in case you downloaded the old version)Students use the 'round to 1sf' rule to estimate the answers to calculations and compare them to the actual answer. Comparing to the key they then assign a color to each question.Finally; using the question numbers along with their colors they complete the grid at the top to get an image of superman. The image is not one that they will be able to figure out in advance.
