Students use rulers to represent various fractions as lengths in this lesson. Once students demonstrate understanding that a fraction can be represented as part of a linear region, they describe part of a linear region using fractions and measure fractional lengths using a standard ruler. This lesson takes teachers through the activities step-by-step.

Grade 3
- Goal 1: Number and Operations - The learner will model, identify, and compute with whole numbers through 9,999.
- Objective 1.05: Use area or region models and set models of fractions to explore part-whole relationships.
- Represent fractions concretely and symbolically (halves, fourths, thirds, sixths, eighths).
- Compare and order fractions (halves, fourths, thirds, sixths, eighths) using models and benchmark numbers (zero, one-half, one); describe comparisons.
- Model and describe common equivalents, especially relationships among halves, fourths, and eighths, and thirds and sixths.
- Understand that the fractional relationships that occur between zero and one also occur between every two consecutive whole numbers.
- Understand and use mixed numbers and their equivalent fraction forms.
- Objective 1.06: Develop flexibility in solving problems by selecting strategies and using mental computation, estimation, calculators or computers, and paper and pencil.
- Objective 1.05: Use area or region models and set models of fractions to explore part-whole relationships.
- Goal 2: Measurement - The learner will recognize and use standard units of metric and customary measurement.
- Objective 2.01: Solve problems using measurement concepts and procedures involving:
- Elapsed time.
- Equivalent measures within the same measurement system.
- Objective 2.02: Estimate and measure using appropriate units.
- Capacity (cups, pints, quarts, gallons, liters).
- Length (miles, kilometers).
- Mass (ounces, pounds, grams, kilograms).
- Temperature (Fahrenheit, Celsius).
- Objective 2.01: Solve problems using measurement concepts and procedures involving:
