Mathematics What’s different with the EIC? EIC aligned to Common Core State Standards Mathematical Practices Formative assessments organized by categories Fewer standards and categories to reflect the K-5 emphasis on number sense Standard algorithms for addition and subtraction in Grade 4

Understanding – Comprehending mathematical concepts, operations, and relations – knowing what mathematical symbols, diagrams, and procedures means. Computing – Carrying out mathematical procedures, such as adding, subtracting, multiplying, and dividing numbers flexibility, accurately, efficiently, and appropriately. Applying – Being able to formulate problems mathematically and to devise strategies for solving them using concepts and procedures appropriately Reasoning – Using logic to explain and justify a solution to a problem or to extend from something known to something not yet known. Engaging – Seeing mathematics as sensible, useful, and doable – if you work at it – and being willing to do the work.

Kindergarten1 st Grade2 nd Grade 1.K.B.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem 1.1.B.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. 1.1.B.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. 1.2.B.1 Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

3 rd Grade4th Grade5 th Grade 1.3.B.6 Understand division as an unknown-factor problem. For example, divide 32 ÷ 8 by finding the number that makes 32 when multiplied by B.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. 1.3.B.8 Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. 1.4.B.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations. 1.4.B.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison. 1.4.B.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. 1.5.B.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. 1.5.B.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × ( ) is three times as large as , without having to calculate the indicated sum or product. 1.5.B.3 Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and given the rule “Add 6” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.

The Common Core State Standards were only written for mathematics, reading, and writing. The science and social studies curricula were written using the Maryland State Curriculum (that used to be the Voluntary State Curriculum). Students in Grade 5 will continue to take Science MSA in the spring. Science and Social Studies were taught in isolation and now they are integrated into reading and writing. Science now includes an engineering component emphasizing STEM activities.

Reading What’s different with the EIC? Complexity: The standards require regular practice with complex text and its academic language Evidence: The standards emphasize reading and writing grounded in evidence from text, both literary and informational Knowledge: The standards require building knowledge through content rich literature Whole group lessons connected with content

14
What’s different in writing? Writing in response to content stimuli Writing in response to content stimuli Topic choice for writing often suggested Topic choice for writing often suggested Up to three writing purposes in every marking period…opinion, narrative, informational/ explanatory Up to three writing purposes in every marking period…opinion, narrative, informational/ explanatory Writing in response to literature, integration with information literacy…research Writing in response to literature, integration with information literacy…research Use of new technology Use of new technology

Collaboration – Working effectively and respectfully to reach a group goal. Effort/Motivation/Persistence – Working diligently and applying effective strategies to achieve a goal or solve a problem; continuing in the fact of obstacles and competing pressures. Intellectual Risk Taking – Accepting uncertainty or challenging the norm to reach a goal. Metacognition – Knowing and being aware of one’s own thinking and having the ability to monitor and evaluate one’s own thinking.

17
Elaboration – Adding details that expand, enrich, or embellish. Flexibility – Being open and responsive to new and diverse ideas and strategies and moving freely among them. Fluency – Generating multiple responses to a problem or idea. Originality – Creating ideas and solutions that are novel or unique to the individual, group, or situation.

18
Analysis – Breaking down a whole into parts that may not be immediately obvious and examining the parts so that the structure of the whole is understood. Evaluation – Weighing evidence, examining claims, and questioning facts to make judgments based upon criteria. Synthesis – Putting parts together to build understanding of a whole concept or to form a new or unique whole.
