GA.MGSE4.OA. Operations and Algebraic Thinking
Use the four operations with whole numbers to solve problems.
MGSE4.OA.1. Understand that a multiplicative comparison is a situation in which one quantity is multiplied by a specified number to get another quantity.
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.
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.
GA.MGSE4.NBT. Number and Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit arithmetic.
MGSE4.NBT.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.
