Identify multiplication expressions for equal groups
key notes:
What is Multiplication?
🔹 Multiplication is repeated addition.
🔹 It helps us find the total number of items in equal groups.
Example: 3 + 3 + 3 = 3 × 3
Equal Groups Concept
🔹 If you have the same number of objects in each group, these are equal groups.
🔹 Count how many groups and how many in each group.
Example: 🍎🍎 🍎🍎 🍎🍎
- Groups = 3
- Apples in each group = 2
- Multiplication expression = 3 × 2
Writing Multiplication Expressions
🔹 Steps:
1️⃣ Count the number of groups
2️⃣ Count how many items are in each group
3️⃣ Multiply: Groups × Items in each group
Tips for Remembering
🔹 Groups come first, items in group come second
🔹 Ask yourself: “How many groups? × How many in each?”
Examples with Emojis
🍪🍪🍪 🍪🍪🍪
- Groups = 2
- Cookies in each group = 3
- Multiplication: 2 × 3 = 6
🐶🐶 🐶🐶 🐶🐶 🐶🐶
- Groups = 4
- Dogs in each group = 2
- Multiplication: 4 × 2 = 8
Check Your Work
🔹 Multiply to see if it matches the total objects.
🔹 Total = Groups × Items in each group ✅
