Skills NSW helps post high school students find courses in vocational training across a wide variety of industries and course providers. Give students 2 minutes to write a question of their own that could be answered using data from the class. After giving students time to discuss the questions in their groups, pause for a whole group discussion.

What's the reason why this domino doesn't belong? Ah, yes, I had noticed the same thing that some of you noticed… A speech bubble out of the yellow shape appears that reads: It’s the only one that shows zero and some more.] On average, what is the furthest, in miles, that each student in this class has ever been from home? Makes sense, doesn’t it? But, is it mathematically correct? I don’t know. My students gave me some pretty good arguments justifying their reasoning! We decided we needed to do some research on the word scalene. Does it only apply to triangles?NSW Department of Education's information on curriculum taught in NSW schools, Aboriginal education and communities & personalised support. 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!

For each of the 4 questions, write a survey question that will help you collect data from the class that can be analyzed to answer the question. What is the average class size at this school?” would produce numerical data with some variability. Learn about the NSW education department, who we are and how we operate. Explore our people, accountabilities, jobs, opportunities and much more. A speech bubble out of the yellow shape over 2:3 appears that reads: Ok, so this one doesn’t work. Why else might 5 not belong? But there was so much I didn't know! This teacher guide--which is not so long but long enough to have depth and lots of new learning--helped me to understand how much more powerful this routine could be if I were more intentional as a teacher. The focus on geometry is interesting to me because it is an area of math teaching that I need to learn more about. The book has an entire chapter called "How Children Become Geometers". This chapter helped me see the big jump kids do from elementary school to high school geometry and how much better we can do to help them build understanding by understanding the levels of understanding kids have and build around geometry.

Shape 5

With your group, decide what the responses for question number 1 have in common. Then do the same for questions numbered 2 and 3. Numerical data are expressed using a number. For example, to answer the question “How tall are the students in this class?” you would measure the height of each student which would result in numerical data. Under the starburst, a blue text box appears with text: Can you make a case for why each one doesn’t belong?] Speaker

This bold-color shapes book is, as the author had hoped, “a resource that can make a meaningful contribution to geometry instruction” (p. 16) but can also reside in an elementary school library. It allows for meaningful conversations, unanswered questions, and deep dives into the subtle and complex similarities and differences between shapes. Which One Doesn't Belong? is a brilliant new math book from Stenhouse. A MUST-HAVE if you teach math at any age I think. But I knew what the student meant, and so did the rest of the class. When I asked him to explain, he said a scalene triangle is a triangle with all three sides having different lengths. A scalene quadrilateral, therefore, is a quadrilateral with all four sides having different lengths.

A speech bubble out of the yellow shape appears that reads: Oh… this one is a near double too… double 5 is 10, then 1 more is 11.] I thought the WODB activity might generate some interesting conversations and serve as a review for our geometry unit which we were concluding. So we gave it a try! 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. Which One Doesn't Belong? and other resources and I've always found the routine to be a good one for math learning and supporting conversations around math.
