PART 1: SELECTING AND SETTING UP A MATHEMATICAL TASK What are your mathematical goals for Determine the height of an object by laying multiple copies of a shorter object end to end. the lesson? (i.e., what do you want students to know and understand about mathematics as a result of this lesson?)

 What are your expectations for  Counters students as they work on and  Buttons complete this task?  Two sided counters  What resources or tools will  Pennies students have to use in their  Paper clips work that will give them  Pencil and paper entry into, and help them reason through, the task? Students will work independently at first and transition into pair groupings.  How will the students work— independently, in small groups, or Students will record their work using math journals/notebook. in pairs—to explore this task? Students will report their data using a document camera or gallery walk.  How will students record and report their work?

How will you introduce students to the Launch 1: I have a shelf in our classroom for all of our books. I need to know if our shelf is tall activity so as to provide access to all enough to fit our books. We don’t have enough rulers for everyone to measure our books. What tools students while maintaining the could we use to measure our books? (Guide student to know that they could use pennies, counters, cognitive demands of the task? buttons, and paperclips. Have students measure their books using non standard units of measurement. Launch 2: Now that we have used all of the different types of non standard units I need you to pick your favorite measuring tool and a partner who chose the same measuring tool. With your partner work together to measure your book. PART 3: SHARING AND DISCUSSING THE TASK  How will you orchestrate the class Solution Path: discussion so that you accomplish your mathematical goals? After measuring independently using different measuring tools invite the students you have  Which solution paths do you want selected to share with the rest of the class. to have shared during the class discussion? In what order will Specific Questions: the solutions be presented? Why?  What do you notice?

How will you extend the task so as to provide additional challenge?
