Lesson Plan Project: Introduction to Fractions
Learning Target: Students will understand the concept of fractions and be able to identify, model, and compare simple fractions.
Success Criterion: Students will successfully complete two practice problems by accurately identifying and modeling fractions using visual representations and will be able to explain the differences between the fractions presented.
Vocabulary Words:
- Fraction
- Numerator
- Denominator
- Equivalent Fractions
- Mixed Number
Formula: For converting a mixed number to an improper fraction: \[ \text{Improper Fraction} = (Whole , Number \times Denominator) + Numerator \]
Lesson Steps:
-
Warm-Up Activity (10 minutes):
- Begin with a quick interactive game. Show various shapes on the board (like circles or squares) and ask students to identify how they can be divided into fractions (e.g., "If this circle is divided into 4 equal parts, what would one part be called?").
-
Introduction to Fractions (20 minutes):
- Introduce the concept of fractions using a pie chart and physical items (like pizza slices or paper circles).
- Explain the terms "numerator" and "denominator." Use an example fraction, such as 3/4, and illustrate how the pie would represent this fraction.
- Describe equivalent fractions using visuals, such as showing how 1/2 is the same as 2/4.
-
Modeling Fractions (15 minutes):
- Use graph paper and crayons to allow students to model fractions visually. For example, they can color in 3 out of 4 squares to represent 3/4.
- Provide a few examples on the board and have students model those examples using the colored graph paper (e.g., 1/2, 2/4).
-
Practice Problems (15 minutes):
- Present two problems on the board:
- Model the fraction 2/3 on graph paper.
- Find an equivalent fraction for 1/2.
- Allow students to practice and model these fractions on their own.
- Present two problems on the board:
-
Assessment/Closure (15 minutes):
- Walk around the room to assess students as they work on the practice problems. Ask guiding questions to explore their understanding.
- Conclude with a quick class discussion: "Who can explain what a numerator and denominator are?" and "Can anyone find an equivalent fraction to 2/4?"
Method for Assessment:
- Observation of student participation during activities.
- Review the completed graph paper models and their explanations of the practice problems to determine understanding.

Lesson Plan Goal:
By the end of this lesson, students will feel more confident in their understanding of basic fractions, be able to represent them visually, and identify equivalent fractions.
