This activity helps learners learn about math through a real-world scenario. Three friends are baking cookies for their school’s bake sale. Using real or pretend cookies and plates, learners figure out how many plates they need to fit a certain number of cookies. Then they calculate how many batches of cookies they need to make for the bake sale. This activity guide includes questions to ask, extensions, resources, standards, and blackline masters.
