Step 1
Introduction & Warm-Up
5 minutes
Begin by greeting students and introducing the day's topic: multiplying whole numbers and understanding fractions.
Teacher Script: "Good morning, mathematicians! Today, we're going to sharpen our skills in two very important areas: multiplication and fractions. Who can remind me what multiplication is? What about a fraction?"

Step 2
Multiplication Review
8 minutes
Review multiplication concepts using visuals and examples.
Teacher Script: "Let's start with multiplication. Remember, multiplication is just a faster way to do repeated addition. If I have 3 groups of 4 apples, how many apples do I have in total?" (Guide students to 3 x 4 = 12).
Work through a few examples together.
Display Slide 2 & 3: Slide Deck: Fraction & Multiply Fun for multiplication examples.
Step 3
Introduction to Fractions
8 minutes
Introduce fractions, explaining what the numerator and denominator represent. Use simple, relatable examples like dividing a pizza or a chocolate bar.
Teacher Script: "Now, let's dive into fractions! A fraction is a way to show parts of a whole. The top number, the numerator, tells us how many parts we have. The bottom number, the denominator, tells us how many parts make up the whole. If I cut a pizza into 8 slices and eat 3, what fraction of the pizza did I eat?" (Guide students to 3/8).
Display Slide 4 & 5: Slide Deck: Fraction & Multiply Fun for fraction explanations and examples.
Step 4
Independent Practice: Worksheet
7 minutes
Distribute the Worksheet: Multiply & Conquer Fractions for independent practice. Circulate around the room to provide support and answer questions.
Teacher Script: "You've all done a great job with our review! Now, it's time to show what you know. I'm handing out a worksheet with both multiplication and fraction problems. Work quietly and independently. If you have a question, raise your hand."
(If students finish early, they can review their answers or draw a picture representing a fraction).
Step 5
Wrap-Up & Cool Down
2 minutes
Bring the class back together. Quickly review one multiplication and one fraction problem from the worksheet. Assign the remaining problems for homework if not completed.
Teacher Script: "Great effort everyone! We'll quickly go over a couple of problems. Remember, practice makes perfect! We'll continue exploring these topics next time."
(Collect worksheets for review. Optionally, use a quick exit ticket question related to the lesson for a cool-down activity).

Slide Deck
Fraction & Multiply Fun!
Let's Explore Multiplication & Fractions!
Welcome students and introduce the day's topic. Ask students what they already know about multiplication and fractions to gauge prior knowledge.
What is Multiplication?
Multiplication is a faster way to do repeated addition.
Example: 3 groups of 4 apples = 3 x 4 = 12 apples
Explain multiplication as repeated addition. Use an example to illustrate the concept.
Multiplication Practice
Solve These!
5 x 3 = ?
6 x 7 = ?
8 x 2 = ?
Work through a couple more multiplication examples with the class. Encourage students to participate.
What is a Fraction?
A fraction shows parts of a whole.
Numerator (top number): How many parts you have
Denominator (bottom number): How many parts make up the whole
Example: 1/2, 3/4, 5/8
Introduce fractions. Explain numerator and denominator using a visual aid or a simple drawing on the board.
Fraction Examples
What fraction of the shape is colored?
[Imagine a circle divided into 4 parts, with 1 part colored]
[Imagine a rectangle divided into 3 parts, with 2 parts colored]
Provide clear examples of fractions and ask students to identify the fraction represented by a given visual or scenario.

Answer Key
Multiply & Conquer Fractions Answer Key
Part 1: Multiplication Mania!
-
5 x 6 = 30
Thought Process: Count by 5 six times (5, 10, 15, 20, 25, 30) or recall multiplication facts. -
8 x 4 = 32
Thought Process: Count by 8 four times (8, 16, 24, 32) or recall multiplication facts. -
7 x 9 = 63
Thought Process: Count by 7 nine times or recall multiplication facts. -
12 x 3 = 36
Thought Process: Add 12 three times (12 + 12 + 12 = 36) or recall multiplication facts. -
(Challenge!) 15 x 5 = 75
Thought Process: Multiply 10 x 5 = 50 and 5 x 5 = 25, then add 50 + 25 = 75.
Part 2: Fantastic Fractions!
-
5/8 of the pizza is left.
Thought Process: The whole pizza is 8/8. If 3 slices are eaten, then 8 - 3 = 5 slices are left. So, 5 out of 8 slices is 5/8. -
Draw a shape (e.g., a rectangle, circle, or square) divided into 5 equal parts. Shade in any 2 of those parts.
Thought Process: The denominator (5) tells us how many equal parts the whole is divided into. The numerator (2) tells us how many of those parts to shade. -
The numerator in the fraction 7/10 is 7.
Thought Process: The numerator is the top number in a fraction, representing the number of parts being considered. -
The denominator in the fraction 4/9 is 9.
Thought Process: The denominator is the bottom number in a fraction, representing the total number of equal parts in the whole. -
Place 1/2 exactly in the middle of 0 and 1 on the number line.
Thought Process: 1/2 represents half of a whole. On a number line from 0 to 1, half would be exactly in the center.
