Equal Groups ✦ Fashion MathNerdCroft · Grade 3 · 3.OA.A.1
✦ The Runway Rules
Key Vocabulary
Every top designer knows the lingo! Learn these words before you hit the catwalk. 👜
✦ Equal Groups
Groups that each hold the same number of items. Like displaying the same number of bags on every boutique shelf!
✦ Factors
The two numbers you multiply together. The first factor = number of groups. The second factor = items in each group.
✦ Product
The answer when you multiply! It's the total number of items across all groups combined.
✦ The Fashion Formula
Number of Groups × Items in Each Group = Total Items
3 × 4 = 12
✦ Look Book Example
3 × 4 = 12
"3 groups of 4 handbags"
Group 1 — 4 bags
Group 2 — 4 bags
Group 3 — 4 bags
There are 3 groups, with 4 bags in each.
3 × 4 = 12 handbags in all! 🎉
✨ Trend Tip!
1st factor = how many groups |
2nd factor = how many items per group |
Product = total items
Every group must have the same number of items — that's what makes them equal groups!

Answer Key
For teacher or parent use. Award full credit for any drawing in Section A that correctly shows equal groups matching the equation.
✦ Section A — Style the Shelf (Draw Equal Groups)
1.2 × 3 = 6 (2 groups of 3 handbags)
2.3 × 4 = 12 (3 groups of 4 bows)
3.4 × 2 = 8 (4 groups of 2 sunglasses)
4.5 × 3 = 15 (5 groups of 3 hats)
5.2 × 6 = 12 (2 groups of 6 sneakers)
6.3 × 5 = 15 (3 groups of 5 dresses)
✦ Section B — Count the Collection (Write the Equation)
1.3 groups of 4 bags → 3 × 4 = 12
2.2 groups of 5 bows → 2 × 5 = 10
3.3 groups of 3 hats → 3 × 3 = 9
4.2 groups of 4 sneakers → 2 × 4 = 8
5.3 groups of 2 sunnies → 3 × 2 = 6
6.3 groups of 4 dresses → 3 × 4 = 12
✦ Section C — Fashion House Word Problems
1.3 × 4 = 12 scarves
2.5 × 6 = 30 pairs of sneakers
3.4 × 7 = 28 buttons
4.3 × 8 = 24 necklaces
5.8 × 5 = 40 accessories
Standards alignment: 3.OA.A.1 — Interpret products of whole numbers as the total number of objects in equal groups. Section A grading: Full credit if the drawing shows the correct number of groups, the correct number of items per group, and the equation is complete. Partial credit if groups or item count (but not both) are correct. Watch for: Students sometimes reverse factors (drawing 3 groups of 2 instead of 2 groups of 3). Both are mathematically valid due to the Commutative Property, but 3.OA.A.1 emphasizes that the first factor represents the number of groups.
