Fractions as Numbers
Use equal-part models and number lines to understand a fraction as equal parts of one whole and as a point on a number line.
Find It. Learn It. Master It.
At a Glance
How can equal parts and visual models help us understand a fraction as equal parts of one whole and as a point on a number line?
4,327 = 4,000 + 300 + 20 + 7
Learning Targets
- I can identify the whole and its equal parts.
- I can choose a fraction model or number line that matches the problem.
- I can calculate, explain, and check my answer.

Worked Examples
Show 3/4 on a number line
Divide the distance from 0 to 1 into 4 equal parts because the denominator is 4.
Start at 0 and count 3 equal jumps because the numerator is 3.
The third mark is 3/4.
Common Misconceptions
Treating the denominator as a count instead of the size of the parts
Name the whole and divide it into equal parts first.
Using models with different-sized wholes
Compare fractions only when the wholes are the same size.
Adding denominators when adding like units
Keep the common unit and combine only the number of those units.
Skipping a reasonableness check
Compare the result with 0, 1/2, 1, or the original amount.
Watch, pause, and explain
Use the chapter markers, key vocabulary, and reflection prompts to stay actively engaged while you watch.
Practice until you can explain it
Move from a quick warm-up to guided practice, independent work, and deeper challenges.
Warm-Up
Directions: Use a quick fraction model. Label the whole, equal parts, numerator, and denominator.
A rectangle is split into 6 equal parts. Two parts are shaded. What fraction is shaded?
Guided Practice
Directions: Follow the steps. Draw a fraction bar or number line, label each value, write an equation, and solve.
Mark 3/5 on a number line from 0 to 1. How many equal jumps reach 3/5?
Independent Practice
Directions: Choose a fraction model, show each step, simplify when needed, and enter your final answer.
A whole is divided into 8 equal parts. Write the unit fraction for one part.
Challenge & Real-World Practice
Draw two different shapes that each show 3/4. Explain why both models represent the same fraction.
