• Promote a deeper understanding of the progression of fractions within the Common Core.
• Develop hands-on strategies to build understanding of operations of fractions.
• Reinforce the Lesson in 3 Acts and Instructional planning.
• Practice the use of questioning, mathematical discourse, productive struggle, and formative assessment .
Outcomes for Today
Page 3
I Have….. Who Has
• Let’s play!• What does this have to do with
learning math?• Where does it fit the common core
standards?• What about the Standards of
Mathematical Practice?
Page 4
Rich Task Reflection & Discussion
Share anecdotal notes and pictures of using a rich task in your classroom.
Group Discussion:
After using a rich task, what was different, if anything, in your classroom – prepare student work, discussions, and any other items to share.

Standards of Mathematical Practice
Page 6
What does it mean to “do mathematics?”
The Standards of Mathematical Practice are descriptions of the fundamental skills needed to “do” mathematics. These are our new “basic skills”.
Phil Daro’s Take on the Common Core State Standards for Mathematics
Page 7
What does it mean to “do mathematics?”
• Standards of Math Practice are the “how” of mathematics
• Content Standards are the “what” of mathematics
Page 8
We must get past the idea of mathematics as a collection of algorithms, steps, or procedures. Just getting answers, although important, is not “doing mathematics.”

Journal Reflection
• What is a fraction?
• What happens to the fraction when we increase the whole?
• Write 3 new ideas you learned about fractions today.

Fraction Progression
• 4th Grade – refer to 6-9 to decimals
• 5th Grade – page 11 – 14• 6th Grade – page 5-7• Write the “must do’s” for each
grade level on poster• Gallery Walk

Fraction Using Cuisenaire Rods
Using Cuisenaire rods model:
• 1 + 12 3
• 1 – 12 3
• 1 x 12 3
• 1 x 13 2
• 1 ÷ 12 3

6-8th Grade Progression – Fractions, Ratios and Proportions
• NS - Grade 6 – pg. 5-7• Ratio/Proportion
– Overview – pg. 2-4– Grade 6 – pg. 5-7– Grade 7 – pg. 8-12– Grade 8 – pg. 11-13
• Create a new poster progression• Develop a definition of a ratio and a
definition of a fraction

• Do a Rich Task• Analyze the student journal for student
growth• Compare data from AimsWeb• Complete reflection survey• Final thoughts
Data Collection Time
Page 27
One Student’s Journey• What did you notice at the beginning
• What was their mathematical understanding?
• What was their ability to communicate in writing?
• How confident were they? (affective journaling)
• What growth evidence do you find?
Page 28
AimsWeb Data• Compare Fall/Winter/Spring or make a
prediction for spring• What do you notice whole group?• Determine how much each of your
students grew• What does this tell you?• What will you do with the results?

Reflection Survey
• Please look through your binder and your journals to reflect on all the learning that has taken place this year
• Refer to the handout
