California’s Common Core Content Standards for Mathematics: Number and Operations in Base Ten: Generalize place value understanding for multi-digit whole numbers: 1) Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. Use place value understanding and properties of operations to perform multi-digit arithmetic. 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. 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.

Number and Operations – Fractions Extend understanding of fraction equivalence and ordering. 2) Compare two fractions with different numerators and different denominators by creating common denominators or numerators. 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, e.g., by using a visual fraction model. Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers. 3) Understand a fraction a/b with a > 1 as a sum of fractions 1/b. a. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
