Eureka Math Grade 4, Module 7: Exploring Measurement with Multiplication
In this unit, your child ends the year using multiplication to convert measurements, like 3 feet to 36 inches, 2 pounds to 32 ounces, and 4 hours to 240 minutes. They build conversion tables, solve "times as many" and multi-step story problems about measurement, and review the year's skills. It follows the decimal unit and wraps up the year.

What is my child learning in Module 7?
- Seeing a conversion as a comparison, like 1 foot being 12 times as long as 1 inch. Learn more: Reading multiplication as "times as many"
- Solving comparison stories about measurements, like a rope 4 times as long as a 3-foot rope. Learn more: Story problems about "times as many"
- Solving multi-step measurement stories with all four operations, like finding totals in pounds and ounces. Learn more: Multi-step story problems and leftovers
- Converting feet to inches, yards to feet, pounds to ounces, gallons to quarts, and hours to minutes with conversion tables. Learn more: Converting feet to inches and kilograms to grams
- Adding and subtracting mixed units, like 2 hours 45 minutes plus 1 hour 30 minutes, in story problems. Learn more: Story problems about distance, time, and money
Sample questions to try together
These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
A man is 6 feet tall. A giraffe is 3 times as tall as the man. Which equation finds g, the giraffe's height in feet?
- g = 3 × 6
- 6 = 3 × g
- g = 3 + 6
How you can help
- Talk about time on a walk or ride. If the trip takes 2 hours, ask your child how many minutes that is, and how they knew to multiply by 60.
- Measure a doorway with a tape measure in feet and inches, like 6 feet 8 inches. Ask your child to change it to inches, 80, and check with the tape.
- Use a gallon jug of milk or water. Ask how many quarts it holds, 4, then how many quarts are in 3 gallons, and say it as "3 gallons is 12 quarts."
Where kids can get stuck
- Assuming every unit works in tens, so 1 pound becomes 10 ounces instead of 16.
- Writing 1 hour 45 minutes plus 1 hour 30 minutes as 2 hours 75 minutes, instead of 3 hours 15 minutes.
- Getting a comparison backwards, so a 3-foot rope seems 4 times as long as a 12-foot rope.
Practice makes perfect
Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
