Unit 3: Reasoning and Explaining (MP2 and MP3)

CCSS Mathematical Practices

LEARNING OBJECTIVES FOR UNIT 3

  • You will be able to describe why, to be successful
    in mathematics, all students need to reason and explain.
  • You will be able to explain what it means for students
    to reason abstractly and quantitatively.
  • You will be able to explain what it means for students
    to construct viable arguments and critique the reasoning of others.
     

Unit 3 examines MP2 and MP3, Reasoning and Explaining; specifically how to reason abstractly and quantitatively, construct viable arguments, and critique the reasoning of others. This unit will focus on how students learn to:

  • Construct viable arguments
  • Respond to the reasoning of others
  • Increase the viability of their arguments

Unit 3 highlights a 5th-grade classroom as the students learn to use the reasoning and explaining practices. Although the focus is on one grade level, teachers of all grade levels can transfer the concepts learned to their instructional practices.
