The world’s greatest sculptors, painters, and photographers depend on math to create their art. Not only do artists use elements of composition — such as geometry and proportions — to perfect their work, they also use math behind the scenes in the studio! This week’s word problems show a practical application of math in sketching, sculpting, photography and painting — exactly the kind of thing that every budding artist should learn and understand.

Look at the following word problems and choose the one that’s the right skill level for your child. Have them give it a try. And when they feel they’ve found the answer, check their solution against ours on the next page.
