Lesson Plan

Fraction & Multiply Fun!

Students will be able to accurately multiply whole numbers and represent fractions visually and numerically.

Mastering multiplication and fractions is crucial for everyday problem-solving and forms the bedrock of advanced mathematical concepts. This lesson helps students build confidence and strong foundational skills.

Audience

4th Grade Students

Time

30 minutes

Approach

Through a combination of direct instruction, visual aids, and independent practice.

Prep

Teacher Preparation

15 minutes

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.

Name: ________________________

Part 1: Multiplication Mania!

Solve each multiplication problem.

  1. 5 x 6 =


  2. 8 x 4 =


  3. 7 x 9 =


  4. 12 x 3 =


  5. (Challenge!) 15 x 5 =


Part 2: Fantastic Fractions!

For each image, write the fraction that represents the shaded part.

  1. Imagine a pizza cut into 8 equal slices. If 3 slices are eaten, what fraction of the pizza is left?


  2. Draw a shape and shade in 2/5 of it.











  3. What is the numerator in the fraction 7/10?


  4. What is the denominator in the fraction 4/9?


  5. Look at the number line below. Where would you place 1/2?

Answer Key

Multiply & Conquer Fractions Answer Key

Part 1: Multiplication Mania!

  1. 5 x 6 = 30
    Thought Process: Count by 5 six times (5, 10, 15, 20, 25, 30) or recall multiplication facts.

  2. 8 x 4 = 32
    Thought Process: Count by 8 four times (8, 16, 24, 32) or recall multiplication facts.

  3. 7 x 9 = 63
    Thought Process: Count by 7 nine times or recall multiplication facts.

  4. 12 x 3 = 36
    Thought Process: Add 12 three times (12 + 12 + 12 = 36) or recall multiplication facts.

  5. (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!

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
