Interpret division as an unknown-factor problem.
Apply properties of operations as strategies to multiply and divide. (Students need not use formal terms for these properties.)
Understand subtraction as an unknown-addend problem.
Operations & Algebraic Thinking: Work with equal groups of objects to gain foundations for multiplication.
Operations & Algebraic Thinking: Model and describe addition as putting together and adding to, and subtraction as taking apart and taking from, using objects or drawings.
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
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. Represent verbal statements of multiplicative comparisons as multiplication equations.
