Whole + Fraction Fun Lesson Plan
Whole + Fraction Fun
Tier 2 Small Group Intervention • 5th Grade
15 Minutes
OBJECTIVE
Students will be able to add and subtract fractions from whole numbers by converting whole numbers into equivalent fractions and using number lines as visual aids.
WHY IT MATTERS
Understanding how to combine whole numbers and fractions is a foundational skill for more complex math operations and everyday problem-solving, like baking or measuring.
PREP & MATERIALS
- Print Number Line Worksheets for each student.
- Set up Whole + Fraction Fun Slide Deck.
- Have Answer Key ready for review.
INSTRUCTIONAL STEPS
1
Warm-Up: Fraction Recall
2 MIN
Display Slide 1. Ask: "What is a fraction? How can we represent it?" Briefly review parts of a fraction (numerator, denominator) and their physical meaning in the "Fraction Bakery."
2
Whole Numbers as Fractions
4 MIN
Display Slides 2-3. Explain that any whole number can be written as a fraction (e.g., \(1 = \frac{2}{2}, \frac{3}{3}\)). Demonstrate converting a whole number into an equivalent fraction based on a target denominator.
3
Adding on a Number Line
4 MIN
Display Slide 4. Introduce the worksheet. Guide students through adding a fraction to a whole (e.g., \(1 + \frac{1}{2}\)). Mark the whole number, then count the fraction jumps. Complete Problem #1 together.
4
Subtracting on a Number Line
3 MIN
Display Slide 5. Guide through subtraction (e.g., \(2 - \frac{1}{3}\)). Emphasize converting the whole number to a matching denominator. Show "backwards" movement on the line. Complete Problem #2 together.
5
Independent Practice
2 MIN
Students complete Problems #3-5 independently. Circulate to check for common errors (e.g., counting lines instead of spaces). Review answers using the key.

Whole Numbers are Secret Fractions
Every whole number can be written as a fraction.
The Secret Rule:
\(1 = \frac{2}{2} = \frac{3}{3} = \frac{4}{4}\)

Let's Bake Equivalent Fractions!
If we need halves...
\(1 = \frac{2}{2}\)
If we need thirds...
\(1 = \frac{3}{3}\)
What about 2 wholes?
\(2 = \frac{4}{2} = \frac{6}{3}\)
