Numerator
Tells us how many parts we are counting.
Denominator
Tells us the total number of equal parts in the whole.
Can fractions look different but still be the same amount?
Equivalent Fractions: Same, But Different!
They are fractions that look different but represent the same amount or value.
1/2
=
2/4
Fraction Bar Fun!
1
Fold a strip into halves.
2
Fold another strip into fourths.
3
Fold a third strip into eighths.
What do you notice about 1/2 and 2/4? How about 2/4 and 4/8?
The Golden Rule
To find an equivalent fraction, you can multiply both the numerator (top) AND the denominator (bottom) by the same non-zero number.
Example 1
1/2 → (1×2) / (2×2) = 2/4
Example 2
2/3 → (2×3) / (3×3) = 6/9
Comparing Fractions: Who's Bigger?
When fractions aren't equal, we use comparison symbols:
> Greater Than
< Less Than
= Equal To
Is 1/2 > or < 1/4?
Strategy 1: Common Denominators
1
Find a common multiple for the denominators.
2
Convert both fractions to equivalent fractions with the new denominator.
3
Compare the numerators.
Compare 1/3 and 2/6
1/3 = (1×2) / (3×2) = 2/6
Compare 2/6 and 2/6
1/3 = 2/6
Strategy 2: Benchmark Fractions (1/2)
Sometimes, it's easy to compare fractions by thinking about whether they are greater than, less than, or equal to 1/2.
3/8
Less than 1/2
(Half of 8 is 4)
5/6
Greater than 1/2
(Half of 6 is 3)
Which one is larger? 3/8 or 5/6?

Introduction & Warm-Up
Slide 1: Welcome to the Fraction Funhouse!
Teacher: "Good morning, everyone! Get ready to step into the 'Fraction Funhouse' today, where we're going on an exciting adventure with fractions! Our goal today is to become masters of equivalent fractions and comparing fractions. We'll learn how fractions can look different but be worth the same, and how to tell which fraction is bigger or smaller."
"Let's start by getting our brains warmed up with a quick Warm Up: Fraction Challenge. Please take out your warm-up sheet and look at the shapes. Your task is to write down the fraction that represents the shaded portion of each shape. Don't worry if it feels tricky, just do your best!"
Allow students a few minutes to complete the warm-up. Circulate and observe. Look for students who might be struggling with identifying the denominator (total parts).
Teacher: "Alright, let's go over our answers. Who would like to share the fraction they wrote for the first shape? (Wait for responses). What about the second? (Wait for responses). And the third?"
"Fantastic! Now, let's quickly review: What does the top number of a fraction, the numerator, tell us? (Pause). That's right, it tells us how many parts we are counting. And the denominator, what does that tell us? (Pause). Exactly! It tells us the total number of equal parts in the whole."
15 MINUTES
Exploring Equivalent Fractions
Slide 3: Equivalent Fractions: Same, But Different!
Teacher: "Our first stop in the Funhouse is all about equivalent fractions. The word 'equivalent' sounds a bit fancy, but it just means 'equal in value' or 'the same amount.' So, equivalent fractions are fractions that look different but represent the exact same portion of a whole."
"Imagine we have a delicious pizza. If I eat 1/2 of the pizza, how much have I eaten? (Pause for answers). Now, what if I told you I ate 2/4 of the exact same pizza? Have I eaten more, less, or the same amount? (Take suggestions). That's right! 1/2 and 2/4 represent the same amount of pizza!"
Slide 4: Fraction Bar Fun!
"To see this in action, let's do our Fraction Bar Activity! I've given each of you some paper strips. Please take one strip and fold it in half. Open it up, and label each part '1/2'. Now, take another strip and fold it in half, and then fold it in half again. How many equal parts do you have now? (Wait for: 'Four'). Label each '1/4'. And for a third strip, fold it into halves, then halves again, then halves one more time. How many parts this time? (Wait for: 'Eight'). Label each '1/8'."
Give students time to fold and label. Circulate to assist. Check that students are making crisp creases so the parts are equal.

Part 1: Finding Equivalent Fractions
1. 1/2
Example Visual Model
SHADED 1 OF 2
Equivalent Fractions (Examples)
2/4, 4/8, 5/10
Method: Multiply numerator and denominator by the same number (e.g., 1x2/2x2 = 2/4).
2. 2/3
Example Visual Model
Equivalent Fractions (Examples)
4/6, 6/9, 8/12
Method: Multiply by 2 (2x2/3x2 = 4/6) or by 3 (2x3/3x3 = 6/9).
Part 2: Comparing Fractions
1/2
>
3/8
STRATEGY: BENCHMARK
1/2 is exactly half. For 3/8, half is 4/8. Since 3 < 4, 3/8 is less than half. So 1/2 > 3/8.
2/3
<
5/6
STRATEGY: COMMON DENOMINATOR
3 goes into 6 twice. Multiply 2/3 by 2/2 to get 4/6. Now compare 4/6 and 5/6. Since 4 < 5, 4/6 < 5/6.
1/4
=
2/8
STRATEGY: EQUIVALENCE
1/4 is equivalent to 2/8 (1x2 / 4x2). They represent the same amount.
3/5
>
1/2
STRATEGY: BENCHMARK
For 3/5, the middle (1/2) is 2.5/5. Since 3 > 2.5, 3/5 is more than 1/2.
Part 3: Graphic Organizer (Sample Answer)
FRACTION 1: 3/4 FRACTION 2: 1/3
Strategy Used Explanation of Steps Comparison Result Common Denominator CD of 4 and 3 is 12. 3/4 = 9/12 1/3 = 4/12 3/4 > 1/3
