📘 Word Problems About Equal Groups, Part 1
New Concept
Number of groups Number in each group = Total
What’s next
Next, you’ll use this formula to translate word problems into equations and find the total in different scenarios.
In this Grade 4 Saxon Math lesson, students learn to solve equal groups word problems using the multiplication formula: Number of groups × Number in each group = Total. They practice identifying clue words like "in each," setting up and solving multiplication equations, and applying division when the total or group size is the unknown. The lesson also introduces estimation as a strategy for checking reasonableness of answers.

Section 2
Formula
Number of groups × Number in each group = Total
Example 1: 6 flocks with 8 birds each is birds in all.
Example 2: 9 cars with 6 people in each is people in all.
Example 3: 3 cartons with 12 eggs in each is eggs total.
When you have several groups that are all the same size, don't count one by one! Just multiply the number of groups by the number of items in a single group to find your grand total. It’s a fantastic shortcut for organized counting and works every single time.
Section 3
Spotting the clues
The words in each are a clue to this problem. The words in each usually mean that the problem has an "equal groups" plot.
Problem: 5 cans with 3 balls in each can. Solution: .
Problem: 4 dozen muffins. Solution: .
Think of the words 'in each' as a secret signal that it's time to multiply! Once you spot them, you know you're dealing with equal groups. Just identify the number of groups and the amount 'in each' one, then multiply them together to find the total. Easy peasy!
