Everyday Mathematics Grade 3, Unit 6: More Operations

In this unit, your child takes on two-step number stories, finds patterns in addition and multiplication tables, and multiplies one-digit numbers by multiples of 10, like 4 x 70. It stretches the multiplication facts practiced alongside fractions in the last unit, and the next unit goes back to fractions to compare them and find equal ones.

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 bakery made 500 cookies. They sold 235 on Saturday and 190 on Sunday. How many are left?

  • 75
  • 85
  • 175

How you can help

  1. Plan a snack for a group: if 4 friends each get 3 crackers and the box holds 20, ask your child how many crackers will be left over.
  2. Count by 4s on a walk, one number per step, and ask your child what they notice: do the numbers land on even or odd, and why?
  3. Use prices at the store that end in zero: if a pack of pencils costs 80 cents, ask how many cents 4 packs cost, thinking of 4 groups of 8 tens.

Where kids can get stuck

  • Stopping after the first step, such as finding how many crackers were handed out but not how many are left.
  • Trusting a pattern after a few examples, deciding every multiple of 3 is odd after seeing 3, 9, and 15.
  • Forgetting the tens when multiplying, writing 4 x 70 as 28 instead of 280.

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.
