Third graders learned the vocabulary word, concentric circles- circles that are inside other circles and are evenly spaced out. They gave several examples of concentric circles that they have seen on signs, in nature, and in everyday objects. Some that even I didn’t think of! First we drew concentric half circles then traced them with glue to make the spider’s web. Next we created a three dimensional spider using tinfoil. We painted in the spaces between our concentric half circles and the rest of the background using water colors, then hot glued our spiders to the web.
