Maryland Math 4.AT.A.1
The Standard
Interpret a multiplication situation 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.

What This Standard Means
What Students Need to Do
- Students use multiplication to compare two amounts. They turn phrases like “three times as many” into equations and explain which amount is larger.
What Mastery Looks Like
- Given 6 cards in one pile and 4 times as many in another, a student writes 4 × 6 = 24 and identifies the pile with 24 cards. They can explain that 24 is four times as many as 6.
Common Misconceptions
- Students may add 4 instead of multiplying by 4 when they hear “four times as many.” They may also mix up which amount is being compared and which amount they start with.
How to Assess It
- Exit ticket: Ava has 8 marbles. Ben has 3 times as many. Write an equation, find Ben’s total, and explain what the 3 means.

Ways to Teach It
Build a row of 5 counters, then a row with 3 times as many; label both rows and write an equation.
Ask: “Sam has 7 pencils. Lee has 4 times as many.” Have students write an equation and explain who has more.
Give pairs of students number cards and comparison cards; have them match each statement to an equation and check each other’s choices.
