Common Core State Standards and Assessments Grades 9 - 12 Mathematics Training of the Trainers July 2012 Work Session Answer Keys 1 PARCC Model Content Frameworks for Mathematics (pp 2 -3) Individual End of Course Overviews: • Shows which standards are assessed on a given end-of-course assessment as well as relative cluster emphases. • Neglecting material will leave gaps in student skill and understanding and may leave students unprepared for the challenges of a later course. • Algebra I (pp. 6 - 7) • Geometry (pp 11 – 12) • Algebra II (pp 15 – 17) • Major Content Flag these pages Supporting Content Additional Content • Underlined numerals indicate standards eligible for assessment on two or more end-of course assessments—cross cutting standards. 2 PARCC Model Content Frameworks for Mathematics (page 3) Examples of Key Advances from Previous Grades or Courses: • Highlights some of the major steps in the progression of increasing knowledge and skill from year to year. • Each key advance in the mathematical content also corresponds to a widening scope of problems that students can solve. Discussion of Mathematical Practices in Relation to Course Content: • Highlights some of the mathematical practices and describes how they play a role in each course. • These examples are provided to stress the need to connect content and practices, as required by the standards. 3 PARCC Model Content Frameworks for Mathematics (page 4) Fluency Recommendations: • The high school standards do not set explicit expectations for fluency nor will the PARCC assessments address fluency, but fluency is important in high school mathematics. • Fluency can allow for smooth progress beyond the CCR threshold toward readiness for further study/careers in STEM fields. • Fluency is not meant to come at the expense of understanding; it is an outcome of a progression of learning and thoughtful practice. • Note: Fluency as defined by PARCC means to flow without halting, stumbling or reversing; and, it marks the endpoints of progressions of learning. (PARCC Model Content Frameworks (Grades K – 8, page 8) 4 PARCC Model Content Frameworks for Mathematics (pp 4 - 5) Pathway Summary Tables: (Table 1 and Table 3) • Table 1: Traditional Pathway (page 20) • Table 3: Integrated Pathway (page 35) • Shows three end-of-course assessments’ standards at a glance. • Standards shown by a dot () will be assessed in that course. • Shading indicates standards that are appropriate for more than one end-of-course assessment. • Is consistent with the preceding end-of-course overviews. Flag this page 5 PARCC Model Content Frameworks for Mathematics (pp 4 - 5) Assessment Limits Tables: (Table 2 and Table 4) • Table 2: Traditional Pathway (pp 21 – 24) Flag this page • Table 4: Integrated Pathway (pp 36 – 42) • Specifies how a standard that is appropriate for more than one end-of-course test will be assessed. • The number of standards assessed on more than one end-ofcourse assessment has been kept as small as possible, so as to keep the number of standards in each course from becoming too large. 6 PARCC Model Content Frameworks for Mathematics (pp 43 - 45) Examples of Opportunities for Connections among Standards, Clusters, Domains, or Conceptual Categories: The standards identify a number of connections among conceptual categories; and, connections among standards, clusters, and domains. Examples of Opportunities for Connecting Mathematical Content and Mathematical Practices: Identifies opportunities for connecting the CCSS to individual Standards for Mathematical Practice. 7 Referencing the CCSS for Mathematics Implications for Instruction for F-IF.4 Sample Responses: • Cross-cutting standard: The Algebra I teacher and Algebra II teacher must proactively plan together to scaffold learning. • Assessment limits: Assessment tasks will have a real-world context. Assessment tasks in Algebra II may include logarithmic and trigonometric functions. • Major Content Emphasis in both Algebra I and Algebra II: This standard (along with other standards) will constitute a majority of the assessment; both teachers must ensure fluency of skills and conceptual understanding. May be taught in conjunction with parts of F-IF.7. • Modeling standard: Both teachers must provide real-world examples and contexts in their instruction. 8 Implications for Instruction for N-VM.5 Sample Response: Plus standard: This standard will not appear in the common math curriculum for all students (Algebra I, Algebra II, and Geometry). It will be taught in our fourth year course Common Core Plus. Teachers can be creative in its presentation and assessment until the final version of the PARCC MCF is released. *Note: refer to PARCC Model Content Frameworks for High School Mathematics page 5. 9 Work Session 2 CCSS for Mathematics “Scavenger Hunt” #1. These standards do not dictate curriculum or teaching methods. For example, just because topic A appears before topic B in the standards for a given grade, it does not necessarily mean that topic A must be taught before topic B. A teacher might prefer to teach topic B before topic A, or might choose to highlight connections by teaching topic A and topic B at the same time. #3. Where can a teacher find a list of terms and their definitions for commonly used words in the CCSS for Mathematics? The Glossary On what page(s) can this information be found? Pages 85-90 #4. T or F. There are only two plus standards under the Algebra Conceptual Category. 10 Work Session 2 continued #5. According to the Introduction for Geometry, connections should be made to equations. #6. What are the two “cluster headings” for S-MD? (1) Calculate expected values and use them to solve problems. (2) Use probability to evaluate outcomes of decisions. #7. Using your response from question #6, what is important to note about the standards listed under this particular domain (MD)? All of these standards are plus standards. 11 Work Session 2 continued #8. On what page can N-Q.3 be found? Page 60 #9. Reference the standard listed below: G-GMD.2 #10. Find one person in your group that knows Cavalieri’s principle and summarize it below: Given two solids of equal altitude, if their cross sections are made by parallel planes at the same distance from their respective bases, then the volumes of the two solids are equal. #11. Locate and read the standard reference by F-BF.2. What is important to note about this standard? This is a Modeling standard. 12 Work Session 2 continued #12. Based on your response to question #11, would all students be taught this standard? Yes Justify your response. All standards without a (+) symbol appear in the common math curriculum (Algebra I, Algebra II, and Geometry) for all students. 13 Work Session 2 continued #13. Compare and contrast A-CED.1 and MMF Algebra I Objective 2a using the Venn Diagram below. create rational, quadratic and exponential functions CCSS A-CED.1 linear equations and inequalities solve real world application assessed in Algebra I graph rational coefficients check Algebra I Obj. 2a 14 Work Session 2 continued #14. Given the data set below, do what is expected of a mathematically proficient student as it relates to standards S-ID. 7 and S-ID.8. Cybal’s Summer Exercise Program Week Pounds Lost 5 17 1 8 3 13 4 15 •Slope/rate of change = 2.26 = Cybal lost approximately 2.26 pounds each week. •Y-intercept = 5.9 =Cybal lost approximately 6 pounds at the beginning of her summer exercise program. •Correlation Coefficient = r = 0.998 Interpretation: There is an almost perfect, positive linear relationship between the week and number of pounds that Cybal lost. Also, as the number of weeks increased so did the number of pounds Cybal lost. 15 Work Session 5a: Focusing on a High School CCSS (A-REI.11) #3. Write one Essential Question for this standard.
