Key Ideas, Expectations, and Opportunities

Using Assessment to Meet Individual Needs

The explicit Expectations and assessment tasks in this unit describe what it means to "get it." Providing feedback on these Expectations helps identify students who need to access the content another way, need further practice opportunities, or are ready to extend or deepen their understanding of a concept. Instructional opportunities that help support the varied needs of students also need to be identified. These opportunities provide models that can be replicated or used multiple times and can be used in a variety of settings (e.g., home, transitions, support classroom, as a center).

Tools for Feedback and Monitoring

Monitoring Progress
Progress can be monitored and reported over time using the Unit Assessment Record, Unit Individual Assessment Record, Math Facts Class Record, and by collecting reviewed student work samples in a portfolio.

Feedback Boxes

The Assessment Program serves the
following purposes:

  1. It provides information to teachers about what students know and can do. This information is used to guide instruction. An activity may help teachers answer questions about whole-class instruction: What do I do next? In the next minute? Next lesson? Next class? Next unit? Other assessments may help teachers decide how to support individual students, including those who struggle with a concept and those who are ready to be challenged.
  2. It communicates the goals of instruction to parents and students. What teachers choose to assess communicates to the class what they value. For example, if teachers want students to work hard at communicating problem-solving strategies, then it is important to assess mathematical communication.
  3. It provides feedback to students and parents about student progress. This includes teacher evaluation of student progress as well as students' assessment of their own progress.

Key Mathematical Ideas

The mathematical content in Math Trailblazers is organized around a set of Key Ideas. These Key Ideas are based on the National Council of Teachers of Mathematics (NCTM) Standards for the grade band as well as current thinking in the mathematics education community, e.g., Charles (2005), NCTM (2000), Van de Walle (2005). There is a set of Key Ideas for each content strand: Number, Algebra, Geometry, Measurement, and Data. They are based on "big ideas" in mathematics and describe what students should be able to do within each strand. The Key Ideas are shown in the table in Figure 1.

Number
1. Number Sense: Understand the base-ten number system, recognize relationships among quantities and numbers, and represent numbers in multiple ways. 2. Operations: Understand the meaning of numerical operations and their application for solving problems. 3. Computation and Estimation: Use efficient and flexible procedures to compute accurately and make reasonable estimates.
Algebra 1. Identifying Patterns: Identify and describe patterns and relationships, including how a change in one variable relates to a change in a second variable. 2. Tables and Graphs: Represent patterns and relationships with graphs, tables, and diagrams. 3. Symbols: Represent patterns and relationships with symbols (includes using variables in formulas and as unknowns in equations). 4. Using Patterns: Apply relationships, properties, and patterns to solve problems, develop generalizations, or make predictions.
Geometry 1. Shapes: Identify, describe, classify, and analyze 2- and 3-dimensional shapes based on their properties. 2. Orientation and Location: Use coordinate systems to specify locations and describe spatial relationships. 3. Motion: Apply transformations (slides, flips, and turns) and use symmetry to analyze mathematical situations. 4. Geometric Reasoning: Use visualization, spatial reasoning, and geometric modeling to solve problems.
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. 2. Measurement Skills: Use measurement tools, appropriate techniques, and formulas to determine measurements.
Data 1. Data Collection: Select, collect, and organize data to answer questions, solve problems, and make predictions. 2. Data Representation: Select and create appropriate representations, including tables and graphs, for organizing, displaying, and analyzing data. 3. Data Description: Describe a data set by interpreting graphs, identifying patterns, and using statistical measures, e.g., average and range. 4. Using Data: Apply relationships and patterns in data to solve problems, develop generalizations, and make predictions.

Expectations

To monitor students' growth across and within grades, there is a set of Expectations that describes what students are "expected" to do within each content strand. Expectations show the growth of the mathematical content within the Key Ideas for each strand.

EXPECTATIONS
Use this list of Expectations to assess students on the key concepts and skills in this unit.
E1* Recognize that different partitions of a number have the same total (e.g., 50 + 4 = 40 + 14).
E2 Solve problems (e.g., part-whole, join) involving volume.
E3* Apply the properties of addition (e.g., commutative, associative) to write number sentences that represent the volume of a building.
E4 Make connections between a building of cubes, the building plan, and number sentences.
E5 Identify shapes that are the same size and shape.
E6 Recognize that different shapes can have the same volume.
E7 Identify and measure the dimensions (floor plan, height) of a building.
E8 Count and add cubic units to find volume.
E9 Construct a building plan given the volume (number of cubes), floor plan, and height.
E10* Demonstrate fluency with the subtraction facts related to the addition facts in Group B (3 − 0, 4 − 0, 5 − 1, 5 − 4, 6 − 1, 6 − 5, 7 − 1, 7 − 2, 7 − 5, 7 − 6, 8 − 1, 8 − 2, 8 − 3, 8 − 5, 8 − 6, 8 − 7, 9 − 1, 9 − 8).
E11* Determine the unknown number in an addition or subtraction sentence relating three whole numbers for the facts in Group B.

Unit Assessment Record

Use this vehicle to record student progress on each of the unit's Content Expectations. The Key Assessment Opportunities Chart identifies activities within each lesson that are appropriate for assessing each Expectation in the unit.

Unit Individual Assessment Record

Upon completion of each unit, transfer information from the Unit Assessment Record to Individual Assessment Records. This latter tool becomes a compilation of the progress for each student across the units.

Math Facts Class Record

Use this tool to track the progress of students' fluency with the fact groups that are practiced and assessed in the Daily Practice and Problems.

Feedback Boxes

Feedback Boxes are provided with several activities to report progress toward the Expectations. Look for the box ( ) on the Unit 10 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.
