What’s different about CCSS?
These Standards are not intended to be new names for old ways of doing business. They are a call to take the next step. It is time for states to work together to build on lessons learned
from two decades of standards based reforms. It is time to recognize that standards are not
just promises to our children, but promises we intend to keep.

Standards for Mathematical Practice
“The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important “processes and proficiencies” with longstanding importance in mathematics education.”
(CCSS, 2010)

Standards for Mathematical Practice
• Describe the thinking processes, habits of mind and dispositions that students need to develop a deep, flexible, and enduring understanding of mathematics; in this sense they are also a means to an end. SP1. Make sense of problems
“….they [students] analyze givens, constraints, relationships and goals. ….they monitor and evaluate their progress and change course if necessary. …. and they continually ask themselves “Does this make sense?”
Briars, June 2011 29
Standards for Mathematical Practice
AND….
• Describe mathematical content students need to learn. SP1. Make sense of problems
“……. students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends.”

• What did Mr. Dickinson get out of using the same math task two days in a row, rather than switching to a different task(s)?
• How did the way the lesson was facilitated support the development of the Standards of Practice for students?
• What implications for implementing CCSS does this activity suggest to you?

Standards for [Student] Mathematical Practice
“Not all tasks are created equal, and different tasks will provoke different levels and kinds
of student thinking.”Stein, Smith, Henningsen, & Silver, 2000
“The level and kind of thinking in which students engage determines what they will learn.”
Hiebert, Carpenter, Fennema, Fuson, Wearne, Murray, Oliver, & Human, 1997
Briars, June 2011 37
The Standards for [Student] Mathematical Practice
The 8 Standards for Mathematical Practice – place an emphasis on student demonstrations
of learning…
Equity begins with an understanding of how the selection of tasks, the assessment of tasks, the student learning environment creates great inequity in our schools…
Briars, June 2011 38
Learners should
• Acquire conceptual knowledge as well as skills to enable them to organize their knowledge, transfer knowledge to new situations, and acquire new knowledge.
• Engage with challenging tasks that involve active meaning-making
Briars, June 2011 39
What Are Mathematical Tasks?
Mathematical tasks are a set of problems or a single complex problem the purpose of which is to focus students’ attention on a particular mathematical idea.
Briars, June 2011 40
Why Focus on Mathematical Tasks?
• Tasks form the basis for students’ opportunities to learn what mathematics is and how one does it;
• Tasks influence learners by directing their attention to particular aspects of content and by specifying ways to process information;
• The level and kind of thinking required by mathematical instructional tasks influences what students learn; and
• Differences in the level and kind of thinking of tasks used by different teachers, schools, and districts, is a major source of inequity in students’ opportunities to learn mathematics.

Increasing Task Cognitive Demand: The Handshake Problem
Version 1How many handshakes willthere be if each person inyour group shakes the handof every person once? Tell who was in your group How did you get your
answer? Try to show your solution on
paper
Version 2 How many handshakes will there
be if one more person joins your group?
How many handshakes will there be if two more people join your group?
How many handshakes will there be if three more people join your group?
Organize your data into a table. Do you see a pattern? How many handshakes will there
be if 100 more people join your group?
Generalization: What can be saidabout the relationship between thenumber of people in a group and thetotal number of handshakes?

Cognitive Level of Tasks
• Lower-Level Tasks(e.g., Handshakes Version 1)
• Higher-Level Tasks (e.g., Handshakes Version 2)
The Quasar Project
Briars, June 2011 45
Lower-Level Tasks
• Memorization– What are the decimal equivalents for the
fractions ½ and ¼?
• Procedures without connections
– Convert the fraction 3/8 to a decimal.
Briars, June 2011 46
Higher-Level Tasks
• Procedures with connections– Using a 10 x 10 grid, identify the decimal and
percent equivalents of 3/5.
• Doing mathematics
– Shade 6 small squares in a 4 x 10 rectangle. Using the rectangle, explain how to determine:
a) The decimal part of area that is shaded;
b) The fractional part of area that is shaded.
Briars, June 2011 47
Implementation Issue
Do all students have the opportunity to engage in mathematical tasks that
promote students’ attainment of the mathematical practices on a regular basis?
Briars, June 2011 48
Opportunities for all students to engage in challenging tasks?
• Examine tasks in your instructional materials:– Higher cognitive demand?
– Lower cognitive demand?
• Where are the challenging tasks?• Do all students have the opportunity to grapple
with challenging tasks?• Examine the tasks in your assessments:
– Higher cognitive demand?
– Lower cognitive demand?

Algebrafy This Task
Jack wants to save to buy a CD player that costs $35. He makes $5 per hour babysitting. How many hours will he need to work in order to buy the CD player?
Blanton & Kaput, 2003
Briars, June 2011
Creating A Classroom Culture and Practices that Promote Algebraic Reasoning
• Incorporate conjecture, argumentation, and generalization in purposeful ways so that students consider arguments as ways to build reliable knowledge
• Respect and encourage these activities as standard daily practice, not as occasional “enrichment” separate from the regular work of learning and practicing arithmetic
Blanton & Kaput, 2003, p.74
Briars, June 2011 55
Leading with the Mathematics Practices
• Build upon/extend work on NCTM Processes and NRC Proficiencies
• Phase in implementation
• Consider relationships among the practices
• Analyze instructional tasks in terms of opportunities for students to regularly engage in practices.

Does It Always Work?
Looking for “Key Words” or “Clue Words” is sometimes taught to children to help them choose the operation to solve a word problem. Does it always work?
• Try to solve each type of problem in the table using “key words.”
• Did you always get the correct answer using this method? For which problems does it work? For which problems, if any, doesn’t it work?
Briars, June 2011
Operations and the Problems They Solve
• To what extent do your instructional materials provide opportunities for students to develop proficiency with the full range of situations that can be modeled by multiplication/division or ratios/rates?
