Customary capacity is one of the most difficult concepts to teach, and it's equally challenging for kids to learn. Because it's so confusing, students need a visual aid to help them remember the basic units and how to convert them. Never fear - it's Gallon Robot to the rescue! Students can create their own Gallon Robot models from this set of patterns. The illustration of Gallon Robot is shown in color because it's recommended that you print the patterns on colored paper. However, the patterns themselves are black and white outline images. Download it here from my TpT Store. Please follow on TpT me if you like it to hear about more of my freebies.
