I think it would also be very interesting to have the students write their own reflections. Did they find this activity interesting and why? What do they think they learned from this activity? OK, so this one doesn't work. Why else might five not belong? What are you thinking? Ah, OK. Yes, lots of different answers. But some of you are thinking this as well. Skills NSW helps post high school students find courses in vocational training across a wide variety of industries and course providers.

Which One Doesn’t Belong? has won the Mathical Book Prize, which will be presented to Christopher Danielson at the National Math Festival in Washington, DC on April 22, 2017. The Mathical Book Prize is an annual award for fiction and nonfiction books that inspire children of all ages to see math in the world around them. On average, what is the furthest, in miles, that each student in this class has ever been from home?

A green starburst shape appears in the upper right corner. Inside is text: Which one doesn’t belong?] Categorical data are expressed using characteristics. For example, to answer the question “What brand of phones do people use?” you would survey several people and their answers result in categorical data. Danielson writes, “I made this book to spark conversations, thinking and wonder” (p. 36). He has succeeded. I enjoyed using this book to facilitate conversations with first and fourth graders. Students were engaged and were eager to communicate their ideas and listen to others. I noticed improvement in their ability to craft mathematical arguments in support of their choices. In the end, the fourth graders composed their own set of shapes to challenge others with “which one doesn’t belong.” I also shared the book with colleagues and even brought it out at a family party.

These are examples non-statistical questions because they are answered by collecting data that does not vary: With your group, decide what the responses for question number 1 have in common. Then do the same for questions numbered 2 and 3. A speech bubble out of the yellow shape appears that reads: This one is also the only even number… all of the others are odd!] Even though the book says “every answer can be correct,” my students had a hard time believing that two, three, or four different answers could all be correct. We decided to find out! My classes thoroughly enjoyed this book and our conversations about shapes. It generated deep thinking and brought up a few questions that we are still wondering about. In a good way!’We started off with the first set of figures and I asked everyone to think silently about which figure didn’t belong. I called on Noah to share his thoughts. Noah chose a figure and explained why that figure was different than the rest. So what about this one? What's one reason why this one doesn't belong? OK. Yes, it's... Oh, I almost said it's the only domino with three on it, but it's not actually. Information about working in or operating early childhood education services including outside school hours care. Plus, information for parents including how to choose a service and supporting your child for their transition to school. In the bottom left corner: 4 triangles are joined alternating on their angled sides to form a parallelogram.] Speaker What are the favorite colors of students in this class?” would produce categorical data with some variability.
