The Instructional Tasks Matter:Analyzing the Demand of Instructional Tasks

Page 2: Supporting Rigorous  Mathematics Teaching and Learning

Rationale –Comparing Two Mathematical Tasks

Tasks form the basis for students’ opportunities to learn what mathematics is and how one does it, yet not all tasks afford the same levels and opportunities for student thinking. [They] are central to students’ learning, shaping not only their opportunity to learn but also their view of the subject matter.

Adding It Up, National Research Council, p. 335, 2001

By analyzing two tasks that are mathematically similar, teachers will begin to differentiate between tasks that require thinking and reasoning and those that require the application of previously learned rules and procedures.

Learning Goals and Activities

Participants will:

• compare mathematical tasks to determine the demand of the tasks; and

• identify the Common Core State Standards (CCSS) for Mathematical Content and the Standards for Mathematical Practice addressed by each of the tasks.

Counting Houses TaskMary, Nick, and Jean are collecting donations to support homeless people. Each student starts on a different path. The houses are side-by-side. Which student will visit the most houses and how do you know? Write an equation that describes each part of the students’ paths and explain which student visited the most houses and how you know.

Mary claims she sees a pattern in the Counting Houses Task that she can use to solve the tasks below. 9 + 8 = ___ 9 + 7 = ___ 9 + 6 = ___

8 + 9 = ___ 7 + 9 = ___ 6 + 9 = ___ 10 + 7 = ___ 10 + __ = 16 10 + __ = 15What pattern do you see? ____________________________________________

The Common Core State Standards

Examine the CCSS− for Mathematical Content

− for Mathematical Practice

• Will first grade students have opportunities to use the standards within the domain of Operations and Algebraic Thinking?

• What kind of student engagement will be possible with each task?

• Which Standards for Mathematical Practice will students have opportunities to use?

Page 8: Supporting Rigorous  Mathematics Teaching and Learning

Common Core State Standards for Mathematics: Grade 1Operations and Algebraic Thinking 1.OA

Represent and solve problems involving addition and subtraction.

1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

1.OA.A.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Common Core State Standards, 2010, p. 15, NGA Center/CCSSO

Page 9: Supporting Rigorous  Mathematics Teaching and Learning

Common Core State Standards for Mathematics: Grade 1Operations and Algebraic Thinking 1.OA

Understand and apply properties of operations and the relationship between addition and subtraction.

1.OA.B.3 Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

1.OA.B.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.

Common Core State Standards, 2010, p. 15, NGA Center/CCSSO

Page 10: Supporting Rigorous  Mathematics Teaching and Learning

Common Core State Standards for Mathematics: Grade 1Operations and Algebraic Thinking 1.OA

Add and subtract within 20.

1.OA.C.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Common Core State Standards, 2010, p. 15, NGA Center/CCSSO

Page 11: Supporting Rigorous  Mathematics Teaching and Learning

Common Core State Standards for Mathematics: Grade 1Operations and Algebraic Thinking 1.OA

Work with addition and subtraction equations.

1.OA.D.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

1.OA.D.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ? – 3, 6 + 6 = ?.

The CCSS for Mathematical Practice

1. Make sense of problems and persevere in solving them.

2. Reason abstractly and quantitatively.

3. Construct viable arguments and critique the reasoning of others.

4. Model with mathematics.

5. Use appropriate tools strategically.

6. Attend to precision.

7. Look for and make use of structure.

8. Look for and express regularity in repeated reasoning.

provoke different levels and kinds of student thinking.

Linking to Research/Literature

There is no decision that teachers make that has a greater impact on students’ opportunities to learn and on their perceptions about what mathematics is than the selection or creation of the tasks with which the teacher engages students in studying mathematics.

The Mathematical Task Analysis Guide

Research has identified characteristics related to each of the categories on the Mathematical Task Analysis Guide (TAG).

How do the characteristics that we identified when discussing the Counting Houses Task relate to those on the TAG? Which characteristics describe the Nine Plus a Number Task?

Page 21: Supporting Rigorous  Mathematics Teaching and Learning

The Cognitive Demand of Tasks(Small Group Work)• Working individually, use the TAG to determine if

tasks A – L are high- or low-level tasks.

• Identify and record the characteristics on the TAG that best describe the cognitive demand of each task.

• Identify the CCSS for Mathematical Practice that the written task requires students to use.

• Share your categorization in pairs or trios. Be prepared to justify your conclusions using the TAG and the Standards for Mathematical Practice.
