Ask the children, "What's 1L like?" They'll probably use their hands and just say, "About this much." Even third and fourth graders will give the same answer. This plan uses length, which they've already learned in second grade, to represent volume. To do this, we'll use only rectangular prisms. We'll carefully progress through L → dL → cL → mL, connecting the meaning of each unit to intuitive, easy-to-understand liquid volumes to deepen their understanding. The printouts are not bound. The text will be distributed one sheet at a time. You may feel the urge to explain things along the way, but try not to jump ahead and explain things that are written on later pages. Also, all the necessary explanations are written in the text, so the general rule is not to add any other explanations. Adding extra explanations can sometimes confuse the children. If you feel they don't understand, have them read the same section again. The plan is designed so that even if their understanding is shallow at first, it will deepen as they continue reading.
