### The resources above correspond to the standards listed below:

#### Maryland College and Career-Ready Standards

MD.MA.4.OA. Operations and Algebraic Thinking (OA)
4.OA.A. Use the four operations with whole numbers to solve problems.
4.OA.A.1. Major Standard: Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5x7 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.
4.OA.A.1.1. Knowledge of and ability to apply understanding of multiplication as repeated addition (2.OA.C.4), as “equal groups of” (3.OA.A.1), and the Commutative Property (3.OA.B.5).
MD.MA.4.NBT. Number and Operations in Base Ten (NBT)
4.NBT.B. Use place value understanding and properties of operations to perform multi-digit arithmetic.
4.NBT.B.4. Major Standard: Fluently add and subtract multi-digit whole numbers using the standard algorithm.
4.NBT.B.4.1. Knowledge of various types of algorithms (CCSS, Page 88, Table 1) to perform multi-digit arithmetic.
4.NBT.B.4.2. Ability to apply a standard algorithm in both addition and subtraction problems.
4.NBT.B.5. Major Standard: 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.
4.NBT.B.5.2. Knowledge of and ability to apply the Properties of Operations (CCSS, Page 90, Table 3).
4.NBT.B.5.3. Knowledge of and ability to apply understanding of place value when multiplying multi-digit numbers.
4.NBT.B.6. Major Standard: 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.
4.NBT.B.6.2. Ability to use arrays and area models for multiplication and division (3.MD.C.6 & 3.MD.C.7).
4.NBT.B.6.3. Knowledge of and ability to apply the Properties of Operations (CCSS, Page 90, Table 3).
