MGSE4.OA: : Operations and Algebraic Thinking

MGSE4.OA.1a: : Interpret a multiplication equation as a comparison e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5.

MGSE4.OA.1b: : Represent verbal statements of multiplicative comparisons as multiplication equations.

MGSE4.OA.2: : Multiply or divide to solve word problems involving multiplicative comparison. Use drawings and equations with a symbol or letter for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison. 1

MGSE4.OA.3: : Solve multistep word problems 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 symbol or letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

MGSE4.OA.4: : Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.

MGSE4.OA.5: : Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. Explain informally why the pattern will continue to develop in this way.

MGSE4.NBT: : Number and Operations in Base Ten

MGSE4.NBT.1: : Recognize that in a multi-digit whole number, a digit in any one place represents ten times what it represents in the place to its right.

MGSE4.NBT.2: : Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

MGSE4.NBT.3: : Use place value understanding to round multi-digit whole numbers to any place

MGSE4.NBT.4: : Fluently add and subtract multi-digit whole numbers using the standard algorithm.

MGSE4.NBT.6: : Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

MGSE4.NF: : Number and Operations – Fractions

MGSE4.NF.1: : Explain why two or more fractions are equivalent a/b = (n x a)/(n x b) ex: 1/4 = (3 x 1)/(3 x 4) by using visual fraction models. Focus attention on how the number and size of the parts differ even though the fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

MGSE4.NF.2: : Compare two fractions with different numerators and different denominators, e.g., by using visual fraction models, by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions.

MGSE4.NF.3a: : Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

MGSE4.NF.3b: : Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.

MGSE4.NF.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.

MGSE4.NF.4a: : Understand a fraction a/b as a multiple of 1/b.

MGSE4.NF.4b: : Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number.

MGSE4.NF.6: : Use decimal notation for fractions with denominators 10 or 100.

MGSE4.NF.7: : Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.

MGSE4.MD: : Measurement and Data

MGSE4.MD.1: : Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec.

MGSE4.MD.1b: : Express larger units in terms of smaller units within the same measurement system.

MGSE4.MD.1c: : Record measurement equivalents in a two column table.

MGSE4.MD.2: : Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

MGSE4.MD.7: : Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol or letter for the unknown angle measure.

MGSE4.MD.8: : Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.

MGSE4.G: : Geometry

MGSE4.G.2: : Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

MGSE4.G.3: : Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
