Welcome students and get them excited about learning multiplication! Briefly introduce the topic and the fun title.
What is Multiplication?
Multiplication is a super-fast way to do repeated addition!
Instead of: 2 + 2 + 2 = 6
We can write: 3 x 2 = 6
It means: 3 groups of 2
Start by asking students about the warm-up question from the lesson plan. Guide them to see how repeated addition leads to multiplication.
Key Terms to Know
-
Factors: The numbers you multiply together.
In 3 x 2 = 6, 3 and 2 are the factors. -
Product: The answer to a multiplication problem.
In 3 x 2 = 6, 6 is the product.
Introduce the key vocabulary terms: factors and product. Provide simple examples for each.
Let's See It!
Imagine you have 4 plates, and each plate has 3 cookies.
How many cookies total?
3 + 3 + 3 + 3 = 12
OR
4 x 3 = 12
(Draw 4 plates with 3 cookies each)
Use visual examples to reinforce the concept. Draw groups of objects or use arrays.
Practice Together!
Solve these:
-
5 groups of 2 = ? (Show as 5 x 2)
-
6 x 1 = ?
-
What is 3 times 7?
-
If you have 2 rows of 8 chairs, how many chairs are there?
Work through these examples with the class. Encourage students to explain their thinking.
Multiplication in Real Life!
Where do you see multiplication?
- Buying multiple items at the store.
- Sharing candy with friends.
- Counting rows and columns in a seating chart.
Think of your own example!
Connect multiplication to real-life scenarios to make it relevant.
Quick Challenge!
Maria has 3 boxes of crayons. Each box has 8 crayons. How many crayons does Maria have in total?
Discuss with your partner how you would solve this!
This slide can be used as a quick check for understanding or a lead-in to the worksheet.

Answer Key
Multiplication Practice Answer Key
Part 1: Repeated Addition to Multiplication
-
4 + 4 + 4 = 12
Multiplication problem: 3 x 4 = 12
Thought process: There are 3 groups of 4, so we multiply 3 by 4. -
6 + 6 = 12
Multiplication problem: 2 x 6 = 12
Thought process: There are 2 groups of 6, so we multiply 2 by 6. -
2 + 2 + 2 + 2 + 2 = 10
Multiplication problem: 5 x 2 = 10
Thought process: There are 5 groups of 2, so we multiply 5 by 2.
Part 2: Solve the Multiplication Problems
-
7 x 3 = 21
Thought process: Counting by 7 three times (7, 14, 21) or knowing the basic multiplication fact. -
9 x 2 = 18
Thought process: Counting by 9 two times (9, 18) or knowing the basic multiplication fact. -
5 x 5 = 25
Thought process: Counting by 5 five times (5, 10, 15, 20, 25) or knowing the basic multiplication fact. -
8 x 4 = 32
Thought process: Counting by 8 four times (8, 16, 24, 32) or knowing the basic multiplication fact. -
10 x 6 = 60
Thought process: Counting by 10 six times (10, 20, 30, 40, 50, 60) or knowing the basic multiplication fact. -
11 x 0 = 0
Thought process: Any number multiplied by zero is zero. -
12 x 5 = 60
Thought process: Counting by 12 five times (12, 24, 36, 48, 60) or knowing the basic multiplication fact.
Part 3: Word Problems
-
Mr. Smith has 5 rows of desks in his classroom. Each row has 6 desks. How many desks are there in total?
Solution: 5 x 6 = 30 desks
Thought process: We have 5 groups (rows) with 6 desks in each group. We multiply the number of rows by the number of desks per row. -
Sarah buys 3 packs of stickers. Each pack has 7 stickers. How many stickers did Sarah buy altogether?
Solution: 3 x 7 = 21 stickers
Thought process: We have 3 groups (packs) with 7 stickers in each group. We multiply the number of packs by the number of stickers per pack.
