Slide Deck

Welcome to Fractions Unite!

Today we'll explore how to add fractions with both like and unlike denominators.

Introduce the lesson and capture students' attention by connecting fractions to real-life scenarios. Emphasize that today they will explore adding fractions with both like and unlike denominators.

Understanding Fractions

Fractions represent parts of a whole. They help us understand parts of a class, pizza slices, or even steps in a game.

Explain that fractions are parts of a whole. Use everyday examples, such as slices of pizza or pieces of cake to illustrate the idea of fractions.

Adding Fractions with Like Denominators

Step 1: Make sure the denominators (bottom numbers) are the same.
Step 2: Add the numerators (top numbers) together.
Step 3: Keep the same denominator.

Detail the procedure for adding fractions with like denominators. Use the visual aid to make the process clear. Encourage students to share their observations.

Adding Fractions with Unlike Denominators

Step 1: Find a common denominator.
Step 2: Convert each fraction to an equivalent fraction with the common denominator.
Step 3: Add the numerators and keep the common denominator.

Introduce adding fractions with unlike denominators. Highlight the steps of finding a common denominator before performing addition. Use examples to walk through the process.

Guided Practice

Let's work through some examples:

  1. 1/4 + 2/4
  2. 1/3 + 1/6 (find a common denominator)

Engage the class in a guided practice session. Work through a couple of examples collectively, asking volunteers to explain their method.

Cool-Down & Review

Review:

  • Identify like vs. unlike denominators
  • Find a common denominator when needed
  • Add the numerators together

Any questions?

Conclude the lesson with a brief review. Remind students of the key steps and the importance of checking for common denominators. Ask if there are any questions before ending the session.

Activity

Fraction Addition Visual Aid

This visual aid is designed to help you visualize the process of adding fractions. We'll go step-by-step through both examples of adding fractions with like denominators and unlike denominators.

Section 1: Adding Fractions with Like Denominators

  1. Step 1: Verify the denominators are the same.





  2. Step 2: Add the numerators together while keeping the same denominator.





  3. Step 3: Simplify the fraction if needed.





Example: 1/4 + 2/4

  • Visual: Draw 4 equal parts of a shape. Shade 1 part for the first fraction and 2 parts for the second fraction. Count the shaded parts, which total 3/4.

Section 2: Adding Fractions with Unlike Denominators

  1. Step 1: Find a common denominator.





  2. Step 2: Convert each fraction to an equivalent fraction with the common denominator.





  3. Step 3: Add the numerators together and keep the common denominator.





  4. Step 4: Simplify the resulting fraction if necessary.





Example: 1/3 + 1/6

  • Visual: Show two circles divided into equal parts. The first circle is divided into 3 parts, and the second into 6 parts. Convert 1/3 into 2/6 so that both fractions have a common denominator (6). Then, add to get 3/6, which is simplified to 1/2.

Visual Representations

  • Use color-coded segments to differentiate fractions. For example, use blue for the first fraction and red for the second.
  • Label each segment with its value.
  • Provide arrows and text boxes at each step to explain the process.

When using this visual aid during the lesson, follow along with the steps and refer back to this guide to help solve your problems!
