Mathematical Practices Connecting Content Standards and Mathematical Practices 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. 36 Mathematical Practices (cont.) Connecting Content Standards and Mathematical Practices Practices combine easily, and a single student behavior could be thought of as exhibiting multiple practices at once. - Not a checklist. There is an expectation that the mathematical practices develop through the grades as students grow in mathematical maturity and in the sophistication with which they apply mathematics. - Need to ensure grade-level appropriate expectations. Assessment is moving toward measuring mathematical practices and will be assessed by PARCC in spring 2015. 37 NJ ASK Mathematics Grades 6-8: 2014 Updates • Assessment and Score Reporting for SPRING 2014 will be aligned exclusively to the Common Core State Standards for Mathematics (CCSSM) (corestandards.org). • Raw scores will be reported in the five CCSSM Domains at each grade. • The available points in each Domain reflects the Content Emphases by Cluster in the PARCC Model Content Frameworks (http://www.parcconline.org/parcc-modelcontent-frameworks). • No score will be reported for the Mathematical Practices. 55 Mathematics: Points by Domain Point Breakdown Grade 6 Grade 7 Grade 8 8 8 0 The Number System 14 12 6 Expressions and Equations 14 15 14 Functions 0 0 10 Geometry 7 7 13 Statistics and Probability 6 7 6 Total Points 49 49 49 Ratios and Proportional Relationships 56 NJ ASK Mathematics Grades 6-8: 2014 Reference Sheets • New reference sheets have been developed for grades 6, 7 and 8 to be consistent with the content of the CCSSM. • The punch-out ruler and protractor remain at all three grades. • The equivalents/conversion factors have been altered to be consistent with the PARCC reference sheets at the appropriate grade (http://www.parcconline.org/assessment-administrationguidance). 57 NJ ASK Mathematics Grades 6-8: 2014 Reference Sheets (cont.) • Geometric formulas no longer necessary due to the alignment change have been deleted (e.g.: Grade 6Volume and Surface Area of a Cylinder). • Additional information no longer necessary due to the alignment change have been deleted (e.g.: Grade 8Permutations Formula). • The new Reference Sheets have been posted at http://www.state.nj.us/education/assessment/ms/58/ref/math/ 58 NJ ASK Mathematics Grades 6-8: Additional Updates ALL students are allowed to use blank grid/graph paper during ALL parts of the Mathematics section of the NJ ASK 6-8. 59 NJ ASK 6-8 Mathematics: Calculator Use Policy • Part 1 of the test (10 short constructed-response items) is non-calculator for all students, including students with disabilities. • Three of the remaining 5 parts (parts 4 through 6) are calculator active for all students. These parts will include multiple-choice (MC) and extended constructed-response (ECR) items. 60 NJ ASK 6-8 Mathematics: Calculator Use Policy (cont.) Parts 2 and 3 are non-calculator, except for students with disabilities. These parts will include multiple-choice (MC) and extended constructed-response (ECR) items. Students classified with a specific disability that limits them from calculating mathematically may use a calculator and/or manipulatives (i.e., abacus, number line, counting chips) on parts 2 and 3. 61 NJ ASK 6-8 Mathematics: Calculator Use Policy (cont.) • Students accommodated through the use of calculators must have the assessment administered to them in an alternative setting. • The use of a calculator or other specific manipulatives as an instructional and assessment accommodation must be documented in the student’s IEP or 504 plan. The SCR part will remain non-calculator. • Please see the Test Examiners Manual for more information about the Calculator Use Policy. 62 Mathematics (Grades 6-8 Unchanged for Spring 2014) MC- multiple choice, 1 raw score point SCR- short constructed-response, 1 raw score point ECR- extended constructed-response, 3 raw score points Grade 6 Grade 7 Grade 8 MC 32 32 32 SCR 8 8 8 ECR 3 3 3 Total raw score points possible 49 49 49 Approximate total testing time (including field test content) 133 minutes 133 minutes 133 minutes Item Count by Type (does not include embedded field test content) 63 Mathematics Sample MC Item Grade 7 CCSSM Standard to be Assessed: 7.G.4: Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle. Note: Previously, calculating the area and circumference of a circle were taught in grade 6- see 4.2.6 E.2 of the NJ Core Curriculum Content Standards (CCCS). Item: Find the area, in square centimeters, of the circle to the nearest integer. 15 cm A. 47 (student finds circumference) B. 154 (student rounds radius to 7) C. 177 (correct for 3.14, 22/7, or π button on calculator D. 707 (student uses 15 for radius) Note: Correct answer is C. Distractors contain common student errors. Area and circumference formulas are on reference sheet (see previous slides for more information). Item stems frequently specify units, so units would not be required in these answer choices. 64 Mathematics Sample Non-Calculator Multiple-Choice Item Grade 6 CCSSM Standard to be Assessed: 6.NS.2: Fluently divide multi-digit numbers using the standard algorithm. Note: The expectation is, using the standard algorithm, students will fluently divide multi-digit numbers with and without remainders. 6.NS.2 is a PARCC fluency expectation. See PARCC End of Year (EOY) Evidence Statement key 6.NS.2. Item: Divide 3647 by 14. A. 26 7/26 (quotient place error, incorrect remainder) B. 26 ½ (quotient place error) C. 260 7/26 (incorrect remainder) D. 260 ½ (correct answer) 65 Grade 8 Mathematics Sample ShortConstructed Response Item CCSSM Standard to be assessed: 8.EE.8b: Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Note: This content was previously in NJ CCCS 4.3.12 B.2. Item: Find the coordinates of the point of intersection of the graphs of y=6x-6 and 5y=-30x. Note: For an SCR item students place their answer on a space provided in the answer folder. Answers such as (½,-3); x=.5 and y=-3; .5,-3; etc. would all be graded as correct. No partial credit is awarded on SCR items- the score is a 0 or a 1. 66 Mathematics Sample ShortConstructed Response Item Grade 7 CCSSM Standard to be Assessed: 7.SP.7a: Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. Note: The CCSSM clusters the topic of probability into grade 7 during the middle school grade band (6-8). This is different than the NJ CCCS which spread probability across all three grades. Item: A middle school choir consists of 10 sixth grade students, 8 seventh grade students, and 6 eighth grade students. The choir director selects a member of the choir at random. What is the probability the director selects a member who is in the eighth grade? Note: Hand scoring of SCR items allows 6/24, ¼, .25, or any equivalent to be scored correct. 67 Mathematics Sample ExtendedConstructed Response Item Grade 8 CCSSM Standard to be Assessed: 8.F.2: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). Item: Shown below are two functions Function #1 Function #2 x y 2x-y=-5 1 -2 3 4 4 7 7 16 68 Mathematics Sample ExtendedConstructed Response Item (cont.) What is the rate of change of function #2? Show your work or explain your answer. (Correct answer 3) Which function has the greater rate of change? Show your work or explain your answer. (Correct answer function #2) Express function #2 as an equation. Explain your answer. (Correct answer y=3x-5) Note: Extended-constructed response items are scored on a 3point maximum item specific rubric. See the Spring 2014 Parent, Student and Teacher Information Guide for more details. 69 Mathematics Sample MultipleChoice Item Grade 6 CCSSM Standard to be Assessed: 6.EE.4: Identify when two expressions are equivalent. Item: Which of the following expressions is NOT equivalent to 15x+9? A. 15x+8+1 B. 10x+5x+9 C. 3(5x+9) D. 3(5x+3) Note: Correct answer C. The second term in the binomial 5x+9 should be 3. Important or key words can be bold and capitalized. 70 http://www.state.nj.us/education/sca/ http://www.corestandards.org http://www.parcconline.org/ 71
