More fun with fraction strips
http://illuminations.nctm.org/LessonDetail.aspx?ID=L541
A lesson plan for grades 3–4 Mathematics
In this lesson, one of a multi-part unit, students continue to work with fraction strips to compare and order fractions. This lesson builds on the work done with fraction relationships in the previous lesson. Students develop skills in problem solving and reasoning as they make connections between various fractions. Illuminations provides an activity sheet and detailed instructions for completing the lesson.
Students will:
- Demonstrate understanding that a fraction can be represented as part of a linear region.
- Describe part of a linear region using fractions.
- Compare fractions to determine if one fraction is greater than, less than, or equal to another fraction.
- Order fractions from least to greatest or from greatest to least.
NCTM Standards and Expectations:
Recognize and generate equivalent forms of commonly used fractions, decimals, and percents.
Develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers.

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 1.05: Use area or region models and set models of fractions to explore part-whole relationships.
Grade 4
- Goal 1: Number and Operations - The learner will read, write, model, and compute with non-negative rational numbers.
- Objective 1.03: Solve problems using models, diagrams, and reasoning about fractions and relationships among fractions involving halves, fourths, eighths, thirds, sixths, twelfths, fifths, tenths, hundredths, and mixed numbers.
