  • = Includes a Feedback Box

Benchmark Expectations. Several of the Expectations are prioritized as Benchmark Expectations because they are particularly important concepts and skills to be learned in this unit. Benchmark Expectations identify the concepts and skills that are central to the unit, are prerequisites for learning content in an upcoming unit, are the last significant opportunity for assessment in the curriculum or grade, or are concepts commonly associated with difficulties or misconceptions. These Expectations are marked with an asterisk in the Key Assessment Opportunities Chart.

Feedback Boxes. A Feedback Box is provided for one activity to report progress toward the Expectations. Look for the box ( ) on the Unit 8 Key Assessment Opportunities Chart. See Figure 2. In this unit, students will also get better acquainted with the Math Practices Expectations by discussing them in the context of a specific problem, receiving feedback, reviewing a peer's work, and revising their own work.

Unit 8 Expectations

Math Content

X

Content Expectations. The Expectations assessed in this unit focus on concepts of number and operations, specifically concepts of developing number sense by finding the partitions of numbers. Because all the Algebra Key Ideas arise from and are closely connected to ideas in the other content strands, Expectations related to algebra will also be listed under a second content strand. For example:

Number 1. Number Sense: Understand the base-ten number system, recognize relationships among quantities and numbers, and represent numbers in multiple ways.

E2. Use symbols (e.g., < , >, =) to show comparisons of quantities. (Algebra 2)

The Content section of the Unit 8 Key Assessment Opportunities Chart identifies some of the activities in the unit that are appropriate for assessing students' abilities with expectations related to these algebra concepts.

Number 1

Number Sense: Understand the base-ten number system, recognize relationships among quantities and numbers, and represent numbers in multiple ways.

E1

 Compare and order quantities (e.g., lengths, areas). [1.NBT.3, 1.MD.1]

E2

 Use symbols (e.g., < , >, =) to show comparisons of quantities. (Algebra 2) [1.NBT.3]
Number 2 Operations: Understand the meaning of numerical operations and their applcation for solving problems.

E3

 Represent partitions of quantities using number sentences and area models. (Algebra 3) [1.OA.5]

Measurement 1

Measurement Concepts: Understand measurable attributes of objects or situations (length, area, mass, volume, size, time) and the units, systems, and processes of measurement.

E4

 Recognize that different shapes can have the same area. [3.MD.6; MP1, 6]

Measurement 2

Measurement Skills: Use measurement tools, appropriate techniques, and formulas to determine measurements.

E5

 Measure length in inches. [1.MD.2]

E6

 Find the area of a shape by counting square units and nonstandard units using efficient counting strategies. [1.NBT.1; 3.MD.6; MP1, 5, 6]
Number 3 Computation and Estimation: Use efficient and flexible precedures to compute accurately and make reasonable estimates.

E7

 Use mental math strategies to add (direct modeling, counting strategies, reasoning from known facts) for the facts in Group D with sums to ten. [1.OA.6]

Math Practices

X

Math Practices Expectations. Students use the Math Practices Expectations on the Math Practices page in the Student Activity Book Reference section to help them focus on practices related to both problem solving and communication. Students become more comfortable with these Expectations by reviewing them before, during, and after solving a problem and by deciding how well they are met in their work and the work of others.


The Math Practices section of the Unit 8 Key Assessment Opportunities Chart identifies activities in the unit that are appropriate for assessing students' use and development of the math practices related to problem-solving habits and communication skills. In this unit, students will focus on finding a strategy [MPE2] and using labels [MPE6].
MPE1 Know the problem. I read the problem carefully. I know the questions to answer and what information is important.
MPE2 Find a strategy. I choose a good and efficient strategy for solving the problem. [MP1]
MPE3 Check for reasonableness. I look back at my solution to see if my answer makes sense. If it does not, I try again.
MPE4 Check my calculations. If I make mistakes, I correct them.
MPE5 Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
MPE6 Use labels. I use labels to show what numbers mean. [MP6]
