Free Geometry Quiz for Grade 4

Fourth grade geometry covers a lot of vocabulary in a short stretch — polygon names, angle measures, lines of symmetry, faces and edges of solids. This quiz hits the highest-yield questions that show up across most state tests and curricula. If your child blanks on questions like 'how many sides does a pentagon have,' make a one-page cheat sheet of polygon names; geometry vocabulary almost always rewards memorization more than reasoning at this level.
