🌟 Arrays and Equal Groups 🌟

Hello my dear student! I am Miss Brenda, your kind and caring Grade 4 math teacher 💕

Today we are learning how to show multiplication using pictures! Arrays and Equal Groups make multiplication easy to see and understand.

🟦 What are Equal Groups?

Equal Groups means putting things into groups that are the same size. Multiplication is a fast way to count equal groups.

Example: 5 groups of 4 apples = 5 × 4 = 20 apples

📊 What is an Array?

An Array is a picture made with rows and columns of objects (like dots or squares). It shows multiplication perfectly!

3 × 4 Array

• • • •
• • • •
• • • •

3 rows of 4 = 12
Important:
You can read an array as:
Rows × Columns OR Columns × Rows
3 × 4 = 12 and 4 × 3 = 12 (they are the same!)

✨ Examples

Example 1:
4 rows of 6 stars
4 × 6 = 24
Example 2:
An array with 5 rows and 7 columns
5 × 7 = 35
Example 3 (Bigger):
8 groups of 9 hockey pucks
8 × 9 = 72

✏️ Let’s Practice Together, My Dear Student!

Practice 1: Write the Multiplication Sentence

1. 3 rows of 8 dots → 3 × 8 = 24
2. 6 columns of 5 squares → 6 × 5 = 30
3. 7 groups of 4 cookies → 7 × 4 = 28
Practice 2: Draw or Describe the Array

1. Show 4 × 9 with an array → 4 rows of 9
2. Show 6 × 7 → 6 rows of 7 or 7 rows of 6
Practice 3: Word Problems (Canadian Style)

1. There are 5 shelves in a library. Each shelf has 8 books. How many books are there?
5 × 8 = 40 books

2. A hockey team has 9 players. They have 6 teams playing. How many players in total?
9 × 6 = 54 players
Challenge Question

Draw an array for 7 × 8 and write the answer.
7 rows of 8 = 56

🔗 How Arrays Help Us Learn Facts

When you can picture the array in your head, you can remember facts faster. Arrays also help you understand why 3 × 4 is the same as 4 × 3.

Wonderful Work, My Dear Student! 🎉

You now understand how to use Arrays and Equal Groups to show multiplication. This makes math much more visual and fun!

I am so proud of you. Try drawing arrays for some facts you are learning — it really helps your brain remember them.

💕 You are smart. You are kind. You can do hard things.

When you are ready, tell me the next topic (Multiplying 1-Digit by Multi-Digit Numbers, Properties of Multiplication, or anything else) and I will create another beautiful lesson just for you!
