1. 1 Fraction Progressions PD Module Presented to [group/school] on [date] A Multi-State Effort Developed by State Math Leads from KS, KY, MS, UT, & WY WDE Contact: Laurie.Hernandez@wyo.gov

2. 2 Grades 2 6 Fraction Progressions Agenda Objectives of Presentation Fraction Overview The Meaning of Fractions Equivalent Fractions Comparing Fractions Operations with Fractions

3. 3 OBJECTIVES Gain an understanding of the fraction progressions across Grades 2-6, informed by research on children s cognitive development and the structure of mathematics. Collaborate within and across grades. Further develop professional learning using additional resources by grade level.

4. 4 Key Questions to Consider Throughout the Day: What type of FOCUS do I need in my grade level to help a student be successful on a problem such as this? How do we work together within AND across grade levels to ensure COHERENCE? How do we maintain proper RIGOR in our instruction including: Conceptual Understanding, Fluency, and Application?

5. 5 Fraction Overview Please refer to the Fraction Progressions Overview document. Please read the document individually. Underline the sentences which you believe are the most important in unit development. Share your sentences with the group. (10 min.)

10. 10 Where are the Cookies? Mrs. James left a tray of cookies on the counter early one morning. Larry walked by before lunch and decided to take 1 3 of the cookies on the tray. Later that afternoon Barry came in and ate 1 Terry saw the tray of cookies and ate 1 remaining at that time. The next morning Mrs. James found the tray with only 6 cookies left.

Using number line diagrams, determine which fraction in each pair is larger. a. 4 4 7 b. 5 7 8 c. 3 2 9 5 , 6 , 8 , 2. What rules about the relative sizes of fractions can you state from these examples? Be as precise as you can in expressing your rules, without using the terms: numerator , denominator , top number , or bottom number .

20. 20 Activity (10 min.) Read the section of the Progressions Document on Grade 4 Equivalent Fractions. Work in pairs to answer the following question: How can the use of area models and number line diagrams solidify a student s understanding of fraction comparison?

38. 38 Questions for Further Investigations (7 min.) What opportunities should students be given to assist with building their conceptual understanding of fractions? How do the various models of fractions build understanding? What are the consequences of a student being bound to one model (e.g. only using circles)?

39. 39 Questions for Further Investigations (7 min.) Whole group: How could various models have been used to facilitate understanding of any of the previous activities and what does the student s choice of model tell the teacher about student understanding?(7 min.)

40. 40 Reflections (15 min.) Discuss as a whole group the following: What type of FOCUS do I need in my grade level to help a student be successful on a problems similar to those presented in today s professional development? How do we work together within AND across grade levels to ensure COHERENCE? How do we maintain proper RIGOR in our instruction including: Conceptual Understanding, Fluency, and Application?

41. 41 Next Steps Work with your students, gather student work, re-visit, and share students understanding and misconceptions with team or PLC. What worked? What didn t? Evaluate if individual students are ready to move on to the next concept.

42. 42 Homework Reflection of Conceptual Understanding What opportunities should students be given to assist with building their conceptual understanding of fractions? How do the various models of fractions build understanding? List some possible outcomes of a student being bound to one model? How does your instruction allow for students to develop conceptual understanding of fractions? How is this embedded in your school s math program? How do you provide opportunities for students to demonstrate conceptual understanding of fractions? How does your school s math program support students demonstrating conceptual understanding of fractions?
