Saxon Math Grade 4, Section 2: Multi-Digit Multiplication & Division

In this unit, your child multiplies and divides larger numbers. They multiply up to four digits by one digit and two digits by two digits, divide by one-digit numbers with remainders, and read multiplication as a comparison, like "5 times as many." It follows the place value unit and leads into factors, multiples, and fractions.

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

  1. Ask how many legs 125 chairs have, and have your child find 4 × 125 in parts: 400 + 80 + 20 = 500.
  2. Plan a reading goal. If your child wants to read 150 pages in 6 days, ask how many pages a day that is, and check by multiplying back.
  3. Compare amounts at the store. If one box holds 8 granola bars and a big box holds 6 times as many, ask how many the big box holds.

Where kids can get stuck

  • Forgetting a carried digit, so 3 × 425 comes out as 1,265 instead of 1,275.
  • Leaving a remainder of 8 when dividing by 6, when 8 still holds another group of 6.
  • Getting a comparison backwards, saying 6 is 5 times as many as 30.
