Teacher Notes (not visible to students)

Materials 3 paper clips per group centimeter ruler per group centimeter cubes for each group baggie of shells per group (1 shell that is 1 paperclip long, 1 shell that is 2 paperclips long, and 1 shell that is 3 paperclips long) Science and Engineering Practices in the NGSS 4. Analyzing and Interpreting Data 5. Using Mathematical and Computational Thinking 6. Constructing Explanations 1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
