How is this distinctly different from the NJCCCS? Common Core State Standards in Mathematics Pre-Test QUESTION 1: CRITICAL AREAS (1e, 2d, 4d) Not all of the content in a given grade is emphasized equally in the standards. Some clusters require greater emphasis than the others based on the depth of the ideas, the time that they take to master, and/or their importance to future mathematics or the demands of college and career readiness. In addition, an intense focus on the most critical material at each grade allows depth in learning, which is carried out through the Standards for Mathematical Practice. What are the critical areas at each grade level (K-8)? K–2: 3–5: 6: 7: 8: 2 Common Core State Standards in Mathematics Pre-Test QUESTION 2: GRADE LEVEL CONTENT (1e) In which grade level are the following topics either introduced or emphasized? Grade: ____ Ratios and proportions Probability of chance events Statistics Knowing formulas of area and circumference of a circle Measuring central tendency Grade: ____ Multiplying and dividing whole numbers within 100 Liquid volume Understanding 1/b fractions with denominators of 2,3,4,6,8 Introduction to area Multiplying single digits by multiples of 10 Grade: ____ +/- within 20 Count to 120 starting at any number Use place value Tell and write time in hours and half hours Partition circles and triangles Grade: ____ Grade: ____ Fluently +,-,x,÷ decimals Unit rate Identifying integers on the number line Evaluating Expressions Grade: ____ +/- fractions with unlike denominators Graphing on the coordinate plane Rounding decimals Grade: ____ Square root Graphing linear relationships Introduction to functions Negative exponents Congruence Proving Pythagorean’s Theorem Scatter Plots Grade: ____ Find factor pairs (1-100) Fractional equivalence and comparing fractions (denominators of 2, 3, 4, 5, 6, 8, 10, 100) Decimal notation for 10ths and 100ths.

Describe how the Supporting Cluster (5.MD.1) reinforces the Major Cluster (5.NBT.7). 5.NBT.A.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. 5.MD.B.1 Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems. 4 Common Core State Standards in Mathematics Pre-Test QUESTION 4: RIGOR (1e) In the CCSSM, rigor is defined in the major topics as the pursuit conceptual understanding, procedural skill and fluency, and application. Certain standards complement procedural skills, conceptual understandings of specific content, or expect students to apply and extend a concept to a real world or mathematical problem solving scenario. The “verbs” within each standard provide cues indicating the aspect of rigor being addressed. For example, the standard below addresses a procedural skill by which students should support their calculations using various representations: equations, rectangular arrays, and/or area models. CCSS.Math.Content.4.NBT.B.5 Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. In tasks assessing Conceptual Understanding - the assessed concept should be central to the task - the necessary computational skill should be fairly low - the task should be easy to solve if the student understands the concept - the tasks do not reside in an application In tasks assessing Procedural Skill & Fluency - students are explicitly required to perform a calculation by manipulating numbers and operations to derive an answer (with precision and accuracy) In tasks assessing Application - students are expected to use appropriate concepts and skills - opportunities should exist for students to apply math concepts to real world & mathematical problems Indicate whether each of the standards explicitly call for conceptual understanding, procedural skill and fluency, or application. CCSS.Math.Content.4.NF.B.3a Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. CCSS.Math.Content.4.NF.B.3c Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction. CCSS.Math.Content.4.NF.B.3d Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem. 5 Common Core State Standards in Mathematics Pre-Test QUESTION 5: MULTIPLE REPRESENTATIONS (2a) Promoting a culture of high expectations for all students is a fundamental goal of the Common Core State Standards. In order to participate with success in the general curriculum, students with disabilities, as appropriate, may be provided additional supports based on the principles of Universal Design for Learning (UDL) - which foster student engagement by presenting information in multiple ways and allowing for diverse avenues of action and expression. Multiple Representations allow teachers to present content in multiple modalities to support flexible thinking. These frameworks go beyond concrete representation (e.g. manipulatives) to promote the realistic representation of concepts addressed in multiple settings. Below is an example of a Multiple Representations Framework that supports CCSS Math Cluster 7.NS.A Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. How does each representation (Concrete, Pictorial, and Abstract) support the cluster? 6 Common Core State Standards in Mathematics Pre-Test CONCRETE REPRESENTATIONS 2-color coin counters to represent negatives and positives Number Lines Thermometers and other equally partitioned tools PICTORIAL REPRESENTATIONS Number Lines (Horizontal) Number Lines (Vertical) Distance / Vector Model Adding Integers Addition is modeled as putting a second vector’s tail at the first vector’s head and finding where the second vector’s head extends to. 3 + -4 = -1 Subtracting Integers Subtraction can be thought of as comparing the two vectors p, and q, by putting both tails together (starting each from zero) and asking the question: “How would one extend a vector from the head of p to the head of q?” The length and direction of that vector would be the result of the subtraction. 3 - -4 = 7 ABSTRACT REPRESENTATIONS p – q = p + (-q) Applying Properties of Numbers p - -q = p + q 7 Common Core State Standards in Mathematics Pre-Test QUESTION 6: TASK ANALYSIS (2b, 2d) Common Core-aligned assessment items should align to the meaning, depth and breadth of the standard. Explain whether or not following assessments items 1-4 assess at the level explicitly called for within the language of the standard. 5.NBT.A.2: Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10. 1. 42.5 x 104 = 2. Explain a rule for multiplying by 10; 100; 1000; any whole number power of 10. 3. A student says that she multiplies by 10 by moving the decimal point one place to the right. Why does she do this? 4. The arrow above points to the number 44 on a number line numbered from 0 to 100. Determine the number will the arrow point when the endpoint of 100 is changed to the ranges below.

The Mathematical Practices work together with the content standards; connecting in meaningful ways. Mathematical Practices MP.1 Make sense of problems and persevere in solving them MP.2 Reason abstractly and quantitatively MP.3 Construct viable arguments and critique the reasoning of others MP.4 Model with mathematics MP.5 Use appropriate tools strategically MP.6 Attend to precision MP.7 Look for and make use of structure MP.8 Look for and express regularity in repeated reasoning Characteristics of Mathematical Practice 3 [MP.3], include o o o Students justifying a conclusion Students proving a statement Students explaining the mathematics/reasoning used Where students may be asked to o use diagrams, words, and/or equations in their work o “repair” a flawed argument o use problem solving as a form of argument where the solution is to be laid out as a series of logical, well-motivated steps using precise language Describe how the following task connects MP.3 with standard 7.EE.A.2 Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. 9 Common Core State Standards in Mathematics Pre-Test Ms. Esposito asked her students to generate an expression that describes the number of each term as an expression of the stage (s). ’s in Four students each provided Ms. Esposito with a different expression to describe the number of ’s in a stage. Student A: 5 + 4(s – 1) Student B: 1 + 4(s) Student C: s + s + 2s + 1 Student D: 6s - 1 Which of the students provided the correct expression? Which expressions are equivalent? Select the expression provided by one student and explain how it relates to the pattern. 10 Common Core State Standards in Mathematics Pre-Test QUESTION 8: INSTRUCTION and PLANNING (1e, 1f) Although the CCSSM do not explicitly reference instructional delivery, certain practices, such as strategic planning, are essential to ensure that instruction is well aligned to the intended objective(s). Key planning strategies encourage teachers to Study the standard to highlight key elements Look at aligned assessment items to help plan with the end in mind (i.e. mastery level problems, problems embedding the practices, problems assessing all aspects of rigor) Select tasks that align well to the day’s objective (focusing more so on conceptual understandings initially ) Solve the problems in advance Consider various entry points to determine which will inform the day’s objective Consider potential student errors and misconceptions Which of the 6 planning strategies, if any, are evident in the lesson outlined on the next page? 11 Common Core State Standards in Mathematics Pre-Test A Grade 6 teacher asks students to determine the number of shaded squares border this 10 by 10 figure, (without counting). Her goal is to have students ‘apply and extend their previous understandings of arithmetic to algebraic expressions’. The teacher takes a moment, in a whole group format, to review some of the anticipated and likely errors that students would make. She then captures expressions that students used to generate the correct answer. As an extension to the activity, the teacher asks students to use the captured student responses (below) to generate numerical expressions for a 6 by 6 figure, then an algebraic expression for an n by n figure.

How can this type of “framing” be used to ensure that teachers are embedding many of the essential components in their lesson design? 13 Common Core State Standards in Mathematics Pre-Test RATIOS & PROPORTIONAL REASONING FRAMEWORK: TEACHER NOTES UNDERSTANDING RATIOS UNIT RATE REPRESENTATIONS A ratio is a pair of non-negative numbers, A : B, which are not both 0 associating two (or more) quantities. A units B units Some authors distinguish ratios from rates, using the term “ratio” when units are the same and “rate” when units are different; others use ratio to encompass both kinds of situations. Standards use ratio in the second sense, applying it to situations in which units are the same as well as to situations in which units are different. Relationships of two quantities in such situations may be described in terms of ratios, rates, percents, or proportional relationships. Ratios have associated rates, expressed as the unit rate. A B The unit rate is the numerical part of the rate; the “unit” in “unit rate” is often used to highlight the 1 in “for each 1” or “for every 1.” Equivalent ratios arise by multiplying each measurement in a ratio pair by the same positive number. Proportional relationships involve collections of pairs of measurements in equivalent ratios. A proportion is an equation stating that two ratios are equivalent. Equivalent ratios have the same unit rate. cA = A cB B A proportional relationship is described by an equation of the form y= kx, where k is a positive constant, often called a constant of proportionality. The constant of 𝐵 proportionality, k, is equal to the value . The graph of 𝐴 a proportional relationship lies on a ray with endpoint at the origin.

There are a number of strategies for solving problems that involve ratios.
