Lesson Excerpt:
Mom explained that, although Billy’s mug was taller than Bobby’s it was also narrow. Bobby’s mug was short but wide. So they both had the same amount of chocolate milk. Bobby wasn’t at all sure about that, he could see that Billy’s mug was bigger! So mom told them that when they were finished with their chocolate milk they could wash their mugs and see how much soapy water they could fit into each one.
Who do you think was correct – Bobby or his mom?
