Group norms

Be Responsible For How & What You Learn

Everyone brings prior experience & knowledge. Take ownership of your learning by being on time and staying, doing the reading & reflection to prepare for discussion, and be willing to try out new ideas in your classroom.

Encourage Risk-Taking and Accept All Ideas

When learning and discussing, everyone needs to feel safe& that ideas will be respected, even if there is disagreement. Discussion of new ideas allows everyone to ? their own beliefs & discover new ways of thinking – an essential focus of this book study.

Group Norms


Group norms cont d

Be Your Own Watchdog

Monitor and manage your participation to prevent contributing too much or too little.

Be An Attentive Listener

Listen to each other during the discussion. Turn off your e-mail and refrain from surfing the net during the sessions.

Group Norms - cont’d


Homework review small group

Based on the homework assigned in the previous session, discuss the following questions in a small group:

What have you tried in your classroom as a result of the last session?

What role did you play in the teaching and learning of math?

What role did the students play in their learning?

What discoveries did you and your students make?

What misconceptions, if any, surfaced about the topic? How did you redirect the students?

What suggestions do you have for others when they try this?

Homework Review (Small Group)

    • Connecting Fractions to Real Life

      • In a small group, discuss the following question: “When and where do we use fractions in our lives?”

      • Be prepared to share your ideas with the large group in about 7 minutes.


    During big ideas

    Review the Big Ideas for this chapter (p. 131) for a couple of minutes.

    Using the portions of the grades 3-5 IRPs:

    What grade level do students begin to explore fraction concepts and what methods, if any, are suggested to facilitate this understanding?

    During - Big Ideas


    Top and bottom numbers
    Top and Bottom Numbers of minutes.

    • Get into two groups

      • Room 1 will complete the Frayer Model for numerator

      • Room 2 will complete the Frayer Model for denominator

      • Be prepared to share with the large group and also consider:

        • How would you introduce the terms numerator and denominator to your students in such a way as to promote understanding and not just memorization? (pp. 138-141)


    Parts and whole tasks
    Parts-and-Whole Tasks of minutes.

    • One way to help students strengthen their understanding of fractional parts and the meaning of the top and bottom numbers in a fraction is through exploring parts-and-whole tasks.


    Parts and whole tasks cont d
    Parts-and-Whole Tasks (cont’d) of minutes.

    • Given the whole and the fraction, find the part.

      • If this rectangle is one whole,

        • find one-fourth

        • find two-thirds

        • find five-thirds


    Parts and whole tasks cont d1
    Parts-and-Whole Tasks (cont’d) of minutes.

    • Given the part and the fraction, find the whole.

      • If the red Cuisinaire rod is one-third, what rod is the whole?

      • If the dark green is two-thirds, what rod is the whole?

      • If yellow is five-fourths, what strip is one whole?


    Parts and whole tasks cont d2
    Parts-and-Whole Tasks (cont’d) of minutes.

    • Given the whole and the part, find the fraction.

      • If 10 counters are the whole set, what fraction of the set is 6 counters?

      • 16 counters are what fraction of a whole set of 12 counters?


    Easter egg fractions
    Easter Egg Fractions of minutes.

    • http://illuminations.nctm.org/LessonDetail.aspx?ID=U112


    Parts and whole tasks cont d3
    Parts-and-Whole Tasks (cont’d) of minutes.

    • In groups of 3:

      • How would you present questions such as these to your students?

      • Which questions are the most challenging? Why?

      • What other types of activities could you use with students to further develop these relationships?


    Fraction number sense
    Fraction Number Sense of minutes.

    • Students need to develop fluency and flexibility with fraction number sense just as they do with whole numbers. Number sense with fractions requires that students have a sense of the approximate size of fractions and be able to easily tell which of two fractions is larger.


    Fraction number sense cont d
    Fraction Number Sense (cont’d) of minutes.

    • Work through the instructions in the Stop and Reflect box (p. 147).

    • Do not use:

      • equivalent fractions

      • common denominators

      • cross multiplication

        to find answers.

    • In partners, share your explanations for each answer.


    Fraction number sense cont d1
    Fraction Number Sense (cont’d) of minutes.

    • As a large group, let us review the four conceptual thought patterns for comparison (p. 147).

    • Be prepared to share how your reasoning for selecting the larger fraction compares to these four ideas.

      • Remember that these four methods for comparing fractions should not be taught to students directly, but should be developed through student exploration.


    Fraction number sense cont d2
    Fraction Number Sense (cont’d) of minutes.

    • In two groups, discuss the following questions:

      • How does an understanding of the meaning of the top and bottom numbers in a fraction help students to develop fraction number sense?

      • How do reference points of 0, half, and 1 help students to develop fraction number sense?

      • What activities could you use with students to develop these concepts?


    Equivalent fraction concepts
    Equivalent Fraction Concepts of minutes.

    • Think of at least two different reasons for how you know that

    • Reread Concepts versus Rules (p. 151) to discuss:

      • “All students should eventually be able to write an equivalent fraction for a given fraction. At the same time, the rules should never be taught or used until the students understand what the result means” (p. 151).


    After
    After of minutes.

    • In small groups, develop a Top Ten List for developing fractional concepts with students. Record you list and be prepared to share with the large group.


    After round table sharing
    After - Round-table Sharing of minutes.

    • Reflect Stems

      • I feel good about…

      • I used to… but now I…

      • My goal is… I will know I am on my way when…

      • One thing that worked today was…

      • One question I have…

      • Two things I remember are…

      • If I could do something again differently, I would…


    After evaluation self assessment form
    After - Evaluation & Self-Assessment Form of minutes.

    • Please take a few minutes to complete the evaluation & self-assessment form at this time and e-mail it to me at [email protected] or fax to 867-393-6339.


    After homework
    After - Homework of minutes.

    • Try some of the fraction activities from this chapter with your students and be ready to share your experiences at the next session.

    • Read Chapter 7, Decimal and Percent Concepts and Decimal Computation (pp. 181-203)
