MCAS Mathematics Performance Indicators The MCAS Mathematics Performance Indicator practice tests are designed to help students prepare for the Massachusetts state test in Mathematics. There are two forms of the Performance Indicators available. They are parallel forms that can be administered before instruction and after, or at any time during the school year. The MCAS Finish Line Mathematics Workbook, Grade 7 provides a complete sequence of instruction in the assessed standards of the Massachusetts Mathematics Curriculum Framework. The workbook includes guided practice and independent practice for each mathematics skill in multiple-choice, short-answer, and openresponse formats. A list of assessed skills is available at the back of this guide. The MCAS Mathematics Performance Indicators, Grade 7 are divided into two sessions: Session 1 and Session 2. The booklets should be administered simultaneously on a single day. Sessions 1 and 2 contain multiple-choice, short-answer, and open-response questions. Each multiple-choice question has four answer choices, one of which is the correct answer. Students should circle the letter of the best answer. Short-answer questions require students to provide a written response a short statement or a numeric computation, for example. Open-response questions require a more extensive answer, usually as a written response or by completing a table, chart, or graph. This teacher s guide includes suggestions for using these test preparation materials, directions for administering the Performance Indicator, an answer key, correlations to the Massachusetts Mathematics Curriculum Framework, scoring guidelines and rubrics, a class skill analysis chart for all questions types, a reproducible reference sheet, and a reproducible page of cut-out tools. The chart below provides a sample timetable for administering the Grade 7 Performance Indicator. Session 1 15 multiple-choice questions 60 minutes, plus an additional Day 1 5 short-answer questions 10 minutes for preparation 2 open-response questions Session 2 14 multiple-choice questions 60 minutes, plus an additional Day 1 3 open-response questions 10 minutes for preparation MCAS Mathematics Performance Indicator Form 7A 3

Session 1 Using Your Performance Indicator Mathematics tests today are usually given in multiple sessions. You will probably want your students to work with the MCAS Mathematics Performance Indicator practice tests in the same way. In addition, schedule review sessions as close as possible to the completion of each part; this will enable you to go over the students answers while the contents are still fresh in their minds. Be sure to consider with the students ways in which their written responses could be improved. Directions for using each booklet begin below. Those that you will read aloud to the class are in boldface type and preceded by the word SAY; those that are not meant to be read aloud are in regular type. The directions that follow instruct the students to write their answers in the test booklets. If you prefer to use a separate answer sheet for the multiple-choice questions, reproduce the answer sheet on page 9 of this guide. Remind students to write their name on the answer sheet. Then instruct them on how to fill in the circles clearly. Like actual tests, the Performance Indicators ask students to use particular mathematical tools, such as rulers, as well as a reference sheet for mathematical formulas. Every student should have his or her own set of these tools and a reference sheet. Blackline masters for making them appear on pages 16 17 of this guide. Before beginning the practice materials, copy the master for the tools onto heavy cardstock and cut out and distribute a set of tools and an individual storage envelope to each student. These tools are also available in punch-out form from Continental Press. Alternatively, provide students with similar manipulatives and tools to use. At some levels of the MCAS, calculator use is permitted or required. Supply calculators as needed. Allow 60 minutes for this first session. Make sure each student has a Performance Indicator, Form A, two No. 2 pencils, a set of tools, a reference sheet, and an optional answer form, if you are using it. SAY Turn to the inside front cover of the booklet and write your name on the line provided. For Session 1, you will have 60 minutes to answer the 22 questions. Check to be sure students have written their name on the inside front cover of their booklets. Explain to the students that they should read each multiple-choice question and all four answers carefully, before circling the letter of the best answer. Then take the time to answer any questions the students may have. SAY Open your booklets to page 3. Read, or have a volunteer read, the directions. SAY Read the directions and questions on each page carefully. You may use your tools and reference sheet to help you solve any questions on the test.

MCAS Mathematics Rubric for Open-Response Items Rubrics for the MCAS mathematics items are specific to the individual items. The following rubric provides general guidelines for evaluating the open-response items in the MCAS Mathematics Performance Indicator practice tests. In reviewing student work, tailor the rubric to the learning standard covered in the item. Score Description 4 The student response demonstrates an exemplary understanding of the concepts involved in the specific learning standard. 3 The student response demonstrates a good understanding of the concepts involved in the specific learning standard. Although there is significant evidence that the student is able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result, the response merits 3 points. 2 The student response demonstrates a fair understanding of the concepts involved in the specific learning standard. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points. 1 The student response demonstrates only a minimal understanding of the concepts involved in the specific learning standard. 0 The student response contains insufficient evidence of an understanding of the concepts involved in the specific learning standard to merit any points.

Mike s height is about 88.9% of his father s height; Caleb s height is about 94.1% of his father s height. 29. Open-response [7.G.6] a. K y J L b. Point J is at (2, 2). Translating 7 units to the left meant subtracting 7 from the x-coordinate, and translating 5 units up meant adding 5 to the y-coordinate. So point J had to be at ( 5, 3). c. (a 7, b 5) 30. A [7.P.5] J K L x 31. D [7.P.3] 32. B [7.P.6] 33. B [7.G.2] 34. A [7.N.6] 35. B [7.G.7] 36. B [7.M.2] 37. D [7.M.3] 38. C [7.D.1] 39. Open-response [7.M.3] a. 24 square inches The area of a triangle is one-half the base times the height. The base is 8 inches, and the height is 6 inches, so the area is 0.5 8 6 24 square inches. b. 78.5 square inches The area of a circle is given by the formula A r 2, and the radius is half the diameter, or 5 inches. So the area is approximately 3.14 5 2 78.5 square inches. c. 30.6% The area of ABC is 24 square inches, and the area of the circle is about 78.5 square inches. So ABC covers about 24 78.5 0.306 30.6% of the circle s area. 8 MCAS Mathematics Performance Indicator Form 7B

Massachusetts Mathematics Curriculum Framework, Grade 7 Number Sense and Operations Strand Students engage in problem solving, communicating, reasoning, connecting, and representing as they: 7.N.1 7.N.2 7.N.3 Compare, order, estimate, and translate among integers, fractions, and mixed numbers (i.e., rational numbers), decimals, and percents. Use ratios and proportions in the solution of problems involving unit rates, scale drawings, and readings of maps. Represent numbers in scientific notation (positive powers of ten only) and use that notation in problem situations. 7.N.4 Demonstrate an understanding of absolute value 3 3 3. 7.N.5 Apply the rules of positive integer exponents to the solution of problems. Extend the Order of Operations to include positive integer exponents. 7.N.6 7.N.7 7.N.8 7.N.9 Use the inverse relationships of addition and subtraction, and of multiplication and division, to simplify computations and solve 1 problems, e.g., multiplying by or 0.5 is the same as dividing 2 by 2. Estimate and compute with fractions (including simplification of fractions), integers, decimals, and percents (including those greater than 100 and less than 1). Determine when an estimate rather than an exact answer is appropriate and apply in problem situations. Select and use appropriate operations addition, subtraction, multiplication, division, and positive integer exponents to solve problems with rational numbers (including negatives).

Measurement Strand Students engage in problem solving, communicating, reasoning, connecting, and representing as they: 7.M.1 7.M.2 7.M.3 Select, convert (within the same system of measurement), and use appropriate units of measurement or scale. Given the formulas, convert from one system of measurement to another. Use technology as appropriate. Demonstrate an understanding of the concepts and apply formulas and procedures for determining measures, including those of area and perimeter/circumference of parallelograms, trapezoids, and circles. Given the formulas, determine the surface area and volume of rectangular prisms and cylinders. Use technology as appropriate. Data Analysis, Statistics, and Probability Strand Students engage in problem solving, communicating, reasoning, connecting, and representing as they: 7.D.1 7.D.2 7.D.3 Select, create, interpret, and utilize the following tabular and graphical representations of data: circle graphs, Venn diagrams, stem-and-leaf plots, tables, and charts. Find, describe, and interpret appropriate measures of central tendency (mean, median, and mode) and spread (range) that represent a set of data. Use these notions to compare different sets of data. Use tree diagrams, tables, organized lists, and area models to compute probabilities for simple compound events, e.g., multiple coin tosses or rolls of number cubes.
