In some multiplicative comparison word problems, you are given the number of items in one set, and you are given the "multiplier" amount.
The multiplier amount tells you how many times bigger (or more) the second set is than the first.
I multiplied a whole number by a whole number, so the amount of money Mary saved this month should be more than she saved last month. You are given the amount of the second set, which is a multiple of the unknown first set, and the “multiplier” amount, which tells you how many times bigger (or more) the second set is than the first.
Remember, “bigger” can also mean “longer,” or “wider,” or “taller” in problems involving measurement, or “faster” in problems involving a rate of speed.
Read the tips and guidance and then work through the multiplication and division word problems in this lesson with your children.

Try the three worksheets that are listed within the lesson (you will also find them at the bottom of the page.) In multiplicative comparison problems, there are two different sets being compared. The second set contains multiple copies of the first set.
Taking time to identify what is important, and what is not, is essential.
Use a highlighter on written problems to identify words that tell you what you are solving, and give you clues about which operations to choose.
“Bigger” can also mean “longer,” or “wider,” or “taller” in problems involving measurement, or “faster” in problems involving a rate of speed.
These problems in which you know both the number in one set, and the number in the second set are called “Multiplier Unknown” comparisons, because the multiplier is the part that is unknown.
