Welcome to Fraction Frenzy!
Today, we're going on an adventure to conquer fractions!
Get ready to team up, think smart, and add some fractions!
Welcome students and introduce the day's fun activity. Get them excited!
Quick Review: Adding Fractions
- What's a Fraction? (Part of a whole)
- Why Common Denominators? (You can only add things that are the same 'size' or 'type' – like adding apples to apples!)
- How to find a Common Denominator: Multiply denominators or find the Least Common Multiple (LCM).
- Remember to simplify!
Briefly review what a fraction is and remind them that we need a common denominator to add them.
Game On: Fraction Frenzy!
Your Mission: In teams, draw fraction cards, add them up, and try to reach a sum as close to a target number (e.g., 2) as possible without going over!
Teamwork is Key! Discuss strategies with your teammates.
Explain the game objective clearly. Emphasize teamwork and mental math/scratch paper.
How to Play: The Rules!
- Form Teams: You'll be in groups of 3-4.
- Deal Cards: Each group gets a deck of Fraction Cards and a Fraction Frenzy Game Board.
- Draw Two: Each player draws two fraction cards.
- Add 'Em Up! Find a common denominator and add your two fractions.
- Record: Write your addition problem and answer on your Fraction Frenzy Game Board.
- Goal: Try to get the highest sum without going over the target number (Teacher will announce).
- Winners: The team with the highest sum under or at the target number wins the round!
Go through the rules step-by-step. Demonstrate an example if time permits.
Strategy Time!
- Look for common denominators early.
- Estimate your sum before calculating.
- Work together to check answers.
- Simplify your fractions!
Emphasize careful calculation and encourage peer checking.
Example Round!
Let's say you draw these cards:
1/2 and 1/3
- Common Denominator? (6)
- Equivalent Fractions: 3/6 and 2/6
- Add: 3/6 + 2/6 = 5/6
(If the target is 1, you're good!)
Provide an example problem to ensure everyone understands.
Let the Frenzy Begin!
Ready, set, MATH!
Good luck, Fraction Friends!

Answer Key
Fraction Frenzy Answer Key Examples
This answer key provides examples of fraction addition problems using the denominators from the game. Students will be creating their own problems, so this is a guide for checking their work.
Example 1
Problem: 1/2 + 1/3
Thought Process:
- Identify denominators: 2 and 3.
- Find the least common multiple (LCM) of 2 and 3, which is 6.
- Convert fractions to equivalent fractions with a denominator of 6:
- 1/2 = (1 * 3) / (2 * 3) = 3/6
- 1/3 = (1 * 2) / (3 * 2) = 2/6
- Add the equivalent fractions: 3/6 + 2/6 = 5/6
- Simplify if necessary: 5/6 is already in simplest form.
Answer: 5/6
Example 2
Problem: 3/4 + 1/8
Thought Process:
- Identify denominators: 4 and 8.
- Find the LCM of 4 and 8, which is 8.
- Convert fractions to equivalent fractions with a denominator of 8:
- 3/4 = (3 * 2) / (4 * 2) = 6/8
- 1/8 (already has a denominator of 8)
- Add the equivalent fractions: 6/8 + 1/8 = 7/8
- Simplify if necessary: 7/8 is already in simplest form.
Answer: 7/8
Example 3
Problem: 2/5 + 3/10
Thought Process:
- Identify denominators: 5 and 10.
- Find the LCM of 5 and 10, which is 10.
- Convert fractions to equivalent fractions with a denominator of 10:
- 2/5 = (2 * 2) / (5 * 2) = 4/10
- 3/10 (already has a denominator of 10)
- Add the equivalent fractions: 4/10 + 3/10 = 7/10
- Simplify if necessary: 7/10 is already in simplest form.
Answer: 7/10

- Convert fractions to equivalent fractions with a denominator of 12:
- 1/6 = (1 * 2) / (6 * 2) = 2/12
- 5/12 (already has a denominator of 12)
- Add the equivalent fractions: 2/12 + 5/12 = 7/12
- Simplify if necessary: 7/12 is already in simplest form.
Answer: 7/12
