Today’s Learning Targets
We are learning to …• Understand the meaning and importance of
“explicit and systematic instruction.”• Deepen our understanding of the Number and
Operations: Fractions Domain
Success Criteria
We will be successful when we can…• Identify what “systematic and explicit
instruction” looks like during PIE time.• Clearly explain the mathematical content in
selected Grade 3-5 CCSSM standards and be able to provide examples of the mathematics.
Emerging Key Research Themes• Increased instructional time in addition to core
mathematics taught in Tier 1.• Small-group instruction utilized in all tiers• Explicit methods of instruction (e.g., CRA, Talk Moves)• Use of concrete and pictorial representations to facilitate
conceptual understanding• Strategy instruction for problem solving (e.g., Think Aloud)• Focus on problem solving skills (not just computation)• Careful alignment of instruction and content in Tier 1 and
Tier 2 • Screening and progress monitoring to target deficit areasSource: Adapted from Newman-Gonchar, R., Clarke, B., & Gersten r. (2009). A summary of nine key studies: Multitier intervention
and response to interventions for students struggling in mathematics.Retrieved from www.centeroninstruction.com

Explicit and Systematic Instruction
Read and highlight Recommendation 3
With your group come to consensus on 3-4 important points you would like to share with the group.
Explicit & Systematic Instruction
Summarize key aspects of “explicit and systematic instruction” as defined by this reading.
What do we need to know as teachers to do this well in our intervention groups?

Be prepared to summarize the Standards’ progression of Number and Operations: Fractions.
3rd through 5th Progression
Where does the difficulty with fractions begin? Research says…
• Premature experience with formal procedures may lead to symbolic knowledge that is not based on understanding impeding students’ number and operation sense.
• Some students “have a continuing interference from their knowledge of whole numbers.”
• Difficulty reasoning with fraction symbols as quantities.• Knowledge that is dependent primarily upon memory, rather
than anchored with a deeper understanding of foundational concepts, contributes to incorrect use and misunderstanding of formal algorithms.
---A Focus on Fractions
Learning Target:Deepen our understanding of the Number and Operations: Fractions domain
Examine fractions as numbers using modelsDeepen understanding of partitioningUnderstand and use unit fraction reasoningRead and interpret the cluster of CCSS standards related to fraction concept development.
Examining Partitioning
....“early experiences with physically partitioning objects or sets of objects may be as important to a child’s development of fraction concepts as counting is to their development of whole number concepts” (Behr and Post, 1992)
Stages of Partitioning
Read pgs. 71 – 75 (through stages of partitioning)
Highlight key phrases from the reading
* Star the important ideas
? Question mark the confusing thoughts
Table group discussion summarizing and clarifying thoughts
Work through problem number 1 on pages 77 & 78
Whiteboard Work
Take a slate and divide it in thirds
On each 1/3 draw a model; a area model, a set model, and a number line.
Discuss the features of each model.
Features of Models
What is the whole?
How are equal parts defined?
What does the fraction indicate?
Area Model
The whole is determined by the area of a defined region
Equal areaThe part covered of whole unit area
Set Model
The whole is determined by definition (of what is in the set)
Equal number of objects
The count of objects in the subset of the defined set of objects.
Number LineUnit of distance or length (continuous)
Equal distance
The location of a point in relation to the distance from zero with regard to the defined unit.
Fractions Composed of Unit Fractions
• Fold your fraction strip to show ¾
• How do you see this fraction as
‘unit fractions’?
Making Fraction Strips
White: whole
Green: halves, fourths, eighths
Yellow: thirds, sixths, ninths
?: twelfths
Note relationships among
the fractions as you fold.
Remember – no labels.
Looking at a Whole
• Arrange the open fraction strips in front of you.• Look at the thirds strip. How do you see the
number 1 on this strip using unit fractions?• In pairs, practice stating the relationship between
the whole and the number of unit fractions in that whole (e.g., 3/3 is three parts of size 1/3).
CCSSM 3.NF.1
• Understand a fraction1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
• How do you make sense of the language in this standard connected to the previous activity?
Extension of Unit Fraction Reasoning
Jason hiked 3/7 of the way around Devil’s Lake. Jenny hiked 3/5 of the way around the lake. Who hiked the farthest?
Use fraction strips and reasoning to explain your answer to this question.
Extension 2
Jim and Sarah each have a garden. The gardens are the same size. 5/6 of Jim’s garden is planted with corn. 7/8 of Sarah’s garden is planted with corn. Who has planted more corn in their garden?
Use fraction strips and reasoning to explain your answer to this question.
Whiteboard Work
• write on your whiteboard the reasoning that you used to explain your answer.
• Be sure your reasoning is connected to unit fractions and fraction strips.
Reflect
Think of the work you have done with your PIE group up to this point…
• How will this knowledge help you be more explicit with your instruction?
• Where might you step in with explicit instruction?
