Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8. Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

DoDEA numbers are much bigger. Division emphasis for DoDEA increases in Grade 4. Solving problems with division and the explicit use of variables do not appear until Grade 4. The numbers included in DoDEA standards are much larger. DODEA standards don’t mention measurement quantities nor do they address the conceptual move from groups to arrays.

Divide two-digit whole numbers by one-digit divisors. Use the inverse relationships of addition and subtraction, and multiplication and division to solve problems and verify solutions. Write and solve algebraic equations or inequalities using variables that represent problem situations. Explain the relationship between multiplication and division as inverse operations. The Grade 3 standard uses the word "explain" but the example shows this to be a very close match. CLUSTER: Understand properties of multiplication and the relationship between multiplication and division. Apply properties of operations as strategies to Although DoDEA standards contain all multiply and divide.

DoDEA Standards 4.M.2e Use and interpret variables, mathematical symbols, and properties of addition and multiplication (e.g., commutative, associative, and the distributive property) to write and simplify mathematical expressions and sentences. 5.M.1f Identify and use the distributive property to simplify and/or perform computations.

Explain the relationship between 3.M.1f multiplication and division as inverse operations. CLUSTER: Multiply and divide within 100. 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. By the end of Grade 3, know from memory all products of two one-digit numbers.

Alignment Notes Although the missing factor is not specified, the two DoDEA standards would logically include this. DoDEA expects fact mastery for all operations in Grade 4, but it is not required earlier. CCRSM connects fluency with strategies based on properties of number and operations, which are not specified in DODEA.

Later problem solving with division and use of variables in DoDEA. It should be noted that rounding is not explicitly mentioned in DoDEA estimation strategies. Develop and use strategies to estimate the results of whole number addition and subtraction and verify this. Demonstrate mathematical relationships of quantity in the form of numeric expressions, equations, or inequalities with mathematical symbols. 4.M.1j Use the inverse relationships of addition and subtraction, and multiplication and division to solve problems and verify solutions. 4.M.1k Use estimation to make predictions and check the reasonableness of result. 4.M.2f Write and solve algebraic equations or inequalities using variables that represent problem situations.

For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends. DoDEA Standards 3.M.2a Identify, describe using their own words, and extend the rules of repeating, number, and growing patterns. 3.M.2e Organize and order data in tables to discover patterns and make predictions. Alignment Notes The level of justification in CCRSM is not found in DoDEA standards (no "why" required). There is preliminary pattern work in DoDEA standards that does not occur in CCRSM. 3.M.2a seems to encapsulate earlier DoDEA numeric patterns.

Alignment of DoDEA CCRSM with the DoDEA Academic Standards not aligned Rounding is not explicitly treated in DoDEA standards. 3.M.1g Explain and solve problems involving the sum or difference of two whole numbers up to 10,000. DoDEA standard goes to larger values. Strategies in CCRSM are not referenced. DODEA does not reference use of algorithms or use of properties, etc. 3.M.1i Demonstrate and explain multiplication and division through the use of representations and mathematical symbols where factors are 99 or less. CCRSM is included in the "factors are 99 or less." The emphasis on the pattern in the CCSSM may be developed while teaching multiplication ideas and algorithms.

Identify and generate equivalent forms of common fractions less than one whole, e.g., halves, thirds, quarters, fifths, and tenths; and explain their relationship to a whole. Judge the size of fractions by using benchmarks, e.g., 0, ½, 1; and use the terms greater than, less than, or equal to or appropriate mathematical symbols >, <, or = to compare a fraction to the benchmark. Alignment Notes This specific definition is not explicit in DoDEA standards. DoDEA standards do not include the partitioning of the number line. DoDEA standards do not include the partitioning of the number line. DoDEA standards do not include the partitioning of the number line. See comments linked to parts 3.M.1.A-D. Page 53 DOMAIN DoDEA CCRSM Gap Analysis College and Career Ready Standards for Mathematics (CCRSM) 3.NF.A.3 3.NF.A.3.A Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line. DoDEA Standards 4.M.1l Identify, compare, and order the relative position of fractions and decimals on a number line. 3.M.1c Identify and generate equivalent forms of common fractions less than one whole, e.g., halves, thirds, quarters, fifths, and tenths; and explain their relationship to a whole. DoDEA standard includes concept of equivalence. Fractions are compared to the whole not to each other. Referencing the same point on the number line is not mentioned in this standard (an equality on the same point not mentioned in 4.M.1l.) Use of visual model is included in DoDEA standard example as well. Number line is not mentioned in DoDEA standard but "another way of representing three thirds" is in 2.M.1j. 3.NF.A.3.B Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model. 3.M.1c Identify and generate equivalent forms of common fractions less than one whole, e.g., halves, thirds, quarters, fifths, and tenths; and explain their relationship to a whole. 3.NF.A.3.C Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram. 2.M.1j Use words, numerals, and physical models to represent fractions and their relationship to the whole.

Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model. DoDEA Standards 4.M.1c Judge the size of fractions by using benchmarks, e.g., 0, ½, 1; and use the terms greater than, less than, or equal to or appropriate mathematical symbols >, <, or = to compare a fraction to the benchmark. 4.M.1l Identify, compare, and order the relative position of fractions and decimals on a number line.

Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets. Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

Specificity about scale or key is not present in DoDEA standards and needs to be addressed for alignment. It is not clear that one- and two-step problems are included in 3.M.5c. This would need to be spelled out. The first mention of fractions on a number line in DoDEA is in Grade 4.
