REASON ABSTRACTLY AND QUANTITATIVELY

Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize--to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents--and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved.

Quantitative reasoning entails habits of creating a coherent representation of the problem at hand; considering the units involved; attending to the meaning of quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.

PSSA TESTING CHANGE

The Pennsylvania Department of Education announced that the PSSA tests for next school year, 2013 ? 2014, will continue to assess Pennsylvania standards. The Common Core State Standards will be assessed on the 2014 ? 2015 PSSA in grades 3 ? 8.

MATHEMATICAL PRACTICE #2

- Jordan School District (2011)

KEY SHIFT: APPLICATION Use math and choose the appropriate

concept for application even when not prompted to do so. Provide opportunities at all grade levels for students to apply math concepts in "real world" situations. Teachers in content areas ensure students are using math to make meaning of and access content.

KEY SHIFT: COHERENCE

Begin to count on deep conceptual understanding of core content and build on it. Each standard is not a new event, but an extension of previous learning.

Provide an opportunity for students to make connections between mathematical ideas.

-Barr, Blosveren, and O'Hara (2012) Implementing the Common Core Standards

WHAT DOES THE TASK LOOK LIKE? WHAT DOES THE TEACHER DO?

Task Has relevant realistic content. Requires students to frame solutions in a context. Have solutions that can be expressed with multiple representations.

Teacher Expects students to interpret, model, and connect multiple representations. Prompts students to articulate connections between algebraic procedures and contextual meaning. Links mathematical solution with a question's answer. Explains connections between procedures and meaning.

QUESTIONS TO

ASK STUDENTS What is a situation

that could be represented by this equation? What operation did you use to represent the situation? Why does that operation represent the situation? How do you know your answer is reasonable?

-GO Math! Houghton Mifflin Harcourt (2012)

WHAT DOES IT REALLY MEAN?

More generally, Mathematical Practice #2 asks students to be able to translate a problem situation into a number sentence (with or without blanks) and, after they solve the arithmetic part (any way), to be able to recognize the connection between all the elements of the sentence and the original problem. It involves making sure that the units (objects!) in problems make sense.

So, for example, in decontextualizing a problem that asks how many buses are needed for 99 children if each bus seats 44, a child might write 99?44. But after calculating 2r11 or 2? or 2.25, the student must recontextualize: the context requires a whole number answer, and not, in this case, just the nearest whole number. Successful recontextualization also means that the student knows that the answer is 3 buses, not 3 children or just 3.

MATHEMATICAL PRACTICE #2

WHAT DO PROFICIENT STUDENTS DO?

Students Reason abstractly and quantitatively

Initial

Reason with models or pictorial representations to solve problems. (Grouping/Engaging)

Intermediate

Are able to transfer situations into symbols for solving problems. (Grouping/Engaging)

Convert situations into symbols to appropriately solve problems as well as convert symbols into meaningful situations. (Encourage Reasoning)

-Hull, Balka, and Harbin Miles (2011)

WHAT ARE STUDENTS DOING? WHAT IS THE TEACHER DOING? Students Have the ability to contextualize and decontextualize (navigate between the concrete and the abstract). Fluently move between manipulatives pictures symbols. Understand and can explain the computation methods they use. Teachers Modeling and providing the appropriate tools. Facilitating conversations to connect models and symbols used in mathematical concepts. Make the connection betweWenritme caapntiiopnus lfoartithveesse,lepctiecdtpuhroetoss,. and symbols.
