NCTM: Launching a DiscourseRich Mathematics Lesson Math Empowers February 13, 2015 Can you believe the 100 th day is right around the corner? There are so many great ways to celebrate the 100 th day. If you are in need of a fresh way to celebrate this mathematical milestone, consider asking your students write their own math story problems involving the number 100. Challenge them to create multistep problems and show their solutions with Bar Models. Can your students create threepart bar models? This is a great follow up activity to GO Math! Lessons 5.9 and 5.11. Jan/Feb 2015 Middletown Public Schools Second Grade “How can teachers implement a lesson that promotes purposeful mathematical discourse?” In the attached article, the authors describe how teachers can implement a lesson that promotes purposeful mathematical discourse. The authors use the thinkaloud strategy to model mathematical thinking and that develops conceptual understanding. They detail how a mathematical thinkaloud should also be carefully constructed to set up students for rich conversations with one another about conjectures, multiple strategies, and possible multiple solutions to the tasks that will follow. This careful construction should prompt students to not only talk about their thinking but also listen to and ask questions about one another’s thinking.

Download this app on your iPad. For those developing number sense, download Math Slide 100. 2 Reflection & Formative Assessment Benefits As we enter marking period three with our GO Math! Program, let’s reflect on our use of Formative Assessment. At times, you may wish to use your own problems instead of the “Quick Check” problems in the lesson. The attached research clip from NCTM confirms, “Formative assessment is any assessment task designed to promote students’ learning. These tasks give both teachers and students feedback, so that teaching and learning activities can be altered according to the results.” In other words, a formative assessment is a quick evaluation FOR Learning while a traditional summative assessment is an evaluation OF Learning. Part Whole Model with 2 & 3 parts, Change Model with 1 & 2 steps, and the Comparison Model with 1, 2, & 3 quantities are examples of the different types of story problems our students will encounter. Thinking Blocks (a.k.a. Bar Model) is the tool to help. Thinking Blocks teaches students how to model and solve math word problems.

Task Level A challenges students to determine the number of toothpicks that make up each given pattern. Be sure to read the Primary Version (which is found after level E) when planning.

“How  can  teachers  implement  a  lesson  that    promotes  purposeful  mathematical  discourse?”  

In  the  attached  article,  the  authors  describe  how  teachers  can  implement  a  lesson  that  promotes  purposeful  mathematical  discourse.  The  authors  use  the  think-­‐aloud  strategy  to  model  mathematical  thinking  and  that  develops  conceptual  understanding.  They  detail  how  a  mathematical  think-­‐aloud  should  also  be  carefully  constructed  to  set  up  students  for  rich  conversations  with  one  another  about  conjectures,  multiple  strategies,  and  possible  multiple  solutions  to  the  tasks  that  will  follow.  This  careful  construction  should  prompt  students  to  not  only  talk  about  their  thinking  but  also  listen  to  and  ask  questions  about  one  another’s  thinking.
