Supporting Rigorous Mathematics Teaching and Learning
Using Assessing and Advancing Questions to Target Essential Understandings
Tennessee Department of EducationElementary School MathematicsGrade 5
Rationale
There is wide agreement regarding the value of teachers attending to and basing their instructional decisions on the mathematical thinking of their students (Warfield, 2001).
By engaging in an analysis of a lesson planning process, teachers will have the opportunity to consider the ways in which the process can be used to help them plan and reflect, both individually and collectively, on instructional activities that are based on student thinking and understanding.

Multiplying and Dividing Fractions: Task Analysis
• Study the Grade 5 CCSS for Mathematical Content within the Number and Operations-Fractions domain.
Which standards are students expected to demonstrate when solving the fraction task?
• Identify the CCSS for Mathematical Practice required by the written task.

Number and Operations – Fractions 5.NF
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
5.NF.B.4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
5.NF.B.4a Interpret the product (a/b) × q as a parts of a partition of qinto b equal parts; equivalently, as the result of a sequence ofoperations a × q ÷ b. For example, use a visual fraction model to show (2/3) x 4 = 8/3, and create a story context for this equation. Do the same with (2/3) x (4/5) = 8/15. (In general, (a/b) x (c/d) = ac/bd.)
5.NF.B.4b Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.

Number and Operations – Fractions 5.NF
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
5.NF.B.5 Interpret multiplication as scaling (resizing), by:
5.NF.B.5a Comparing the size of a product to the size of one factor onthe basis of the size of the other factor, without performing theindicated multiplication.
5.NF.B.5b Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence a/b = (n × a)/(n × b) to the effect of multiplying a/b by 1.
5.NF.B.6 Solve real-world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Number and Operations – Fractions 5.NFApply and extend previous understandings of multiplication and division to multiply and divide fractions.
5.NF.B.7 Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.
5.NF.B.7a Interpret division of a unit fraction by a non-zero whole number, and compute such quotients. For example, create a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) x 4 = 1/3.
5.NF.B.7b Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (1/5) = 20 because 20 x (1/5) = 4.
5.NF.B.7c Solve real-world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups of raisins?

Objective
Students will show multiplication of a fraction by a whole number with a model.
Essential Understanding
When you multiply a fraction by whole number, the partitioning of the whole is based on the denominator. The number of partitions taken is the product of the whole number and numerator. This can be show by repeated addition of the fraction the number of times indicated by the whole number.

5.NF.B.4a
When multiplying by a fraction, there is less than 1 whole group/less than 1 in a group therefore, the product will be less than one or both factors. 5.NF.B.4
When dividing a fraction by a whole number, every iteration of the unit fraction needs to be divided by the whole number.
5.NF.B.7a
When dividing a whole number by a unit fraction, the number of times that the unit fraction fits inside the whole number is determined by the denominator. 5.NF.B.7b

Characteristics of Questions that Support Students’ Exploration
Assessing Questions• Based closely on the
work the student has produced.
• Clarify what the student has done and what the student understands about what s/he has done.
• Provide information to the teacher about what the student understands.
Advancing Questions• Use what students have
produced as a basis for making progress toward the target goal.
• Move students beyond their current thinking by pressing students to extend what they know to a new situation.
• Press students to think about something they are not currently thinking about.
LEARNING RESEARCH AND DEVELOPMENT CENTER © 2012 UNIVERSITY OF PITTSBURGH 27
Supporting Students’ Exploration(Analyzing Student Work)
Analyze the students’ responses.
Analyze the student’s group work to determine where there is evidence of student understanding.
What advancing question would you ask the students to further their understanding of an EU?
