Introduction:
Teaching fractions to third graders can be a dynamic and engaging experience when co-teaching strategies are thoughtfully implemented. Co-teaching offers a powerful way to reach diverse learners by leveraging the strengths of two educators working collaboratively. This lesson plan integrates two highly effective co-teaching approaches—One Teach, One Summarize and Teach Half Then Switch—Skills & Rigor—to ensure that all students develop a strong foundational understanding of fractions. These strategies not only enhance student engagement but also allow for differentiated instruction that meets the needs of learners at varying levels of readiness.
In the One Teach, One Summarize approach, one teacher delivers the primary instruction while the other teacher listens actively, takes notes, and then summarizes key points to reinforce learning. This method strengthens student comprehension by allowing them to hear the information twice, in two distinct ways. Teach Half Then Switch—Skills & Rigor divides the class into two groups, with each teacher delivering instruction focused on a specific skill or concept. After a set time, students switch groups, ensuring that they receive well-rounded instruction in multiple formats. This approach allows students to interact with both teachers and engage in different types of learning experiences.
By incorporating these co-teaching strategies, we create a lesson that is not only structured and effective but also fosters collaboration, active engagement, and a deeper understanding of fractions. This lesson is designed to support educators in making fractions meaningful and accessible for all students, while also strengthening the partnership between co-teachers. Whether you are a general education teacher or a special educator, this lesson plan offers practical strategies to enhance student learning and create a supportive, interactive classroom environment.
Lesson Plan: Teaching Fractions in a 3rd-Grade Classroom
Lesson Title: Understanding Fractions Through Co-Teaching Strategies
Grade Level: 3rd Grade
Standards:
- CCSS.MATH.CONTENT.3.NF.A.1: Understand a fraction 1/b as one part of a whole divided into b equal parts.
- CCSS.MATH.CONTENT.3.NF.A.3: Explain equivalence of fractions and compare fractions by reasoning about their size.
Learning Objectives:
- Students will understand the concept of fractions as parts of a whole.
- Students will identify and represent fractions using models and number lines.
- Students will compare simple fractions and recognize equivalent fractions.
Co-Teaching Strategies:
- One Teach, One Summarize
- Teach Half Then Switch—Skills & Rigor
Lesson Sequence:
Warm-Up (10 Minutes) – One Teach, One Summarize
- Teacher A presents a short introduction to fractions using visuals (e.g., pizza slices, fraction bars).
- Teacher B listens and takes notes to summarize key points.
- Teacher B then provides a concise summary of what was just taught and checks for understanding through student responses.
- Quick question prompts:
- “What is a fraction?”
- “Can someone describe 1/4 using an example?”
- “Why do we need fractions in real life?”
Direct Instruction (15 Minutes) – Teach Half Then Switch
- Class is split into two groups.
- Teacher A teaches one half of the students using visual fraction models.
- Teacher B teaches the other half using number lines.
- After 10 minutes, students switch teachers and learn the other method.
- Mini-checks for understanding: Students solve a simple problem related to each method.
Guided Practice (15 Minutes) – Teach Half Then Switch
- Teacher A leads a hands-on fraction activity with half of the students using fraction circles.
- Teacher B guides the other half in a comparison activity using fraction strips.
- After 7-8 minutes, students switch groups and complete the alternate activity.
Independent Practice (10 Minutes) – One Teach, One Summarize
- Teacher A provides students with practice problems to reinforce learning.
- Teacher B walks around to check for understanding and takes notes.
- At the end, Teacher B summarizes the main takeaways and provides quick review questions.
Closure (5 Minutes)
- Review key concepts as a class using a fraction quiz game.
- Ask students to reflect on their learning: “What was easy? What was challenging?”
- Assign a simple take-home activity: Draw a picture representing a fraction and write a sentence about it.
Assessment:
- Informal assessment through teacher observations and questioning.
- Exit ticket: Write one thing you learned about fractions today.
- Review independent practice work to check understanding.
Materials Needed:
- Fraction circles, bars, and strips
- Whiteboards and markers
- Chart paper for visual modeling
- Printed fraction number lines
- Small dry-erase boards for quick checks
Differentiation Strategies:
- Provide extra support with manipulatives for students struggling with fraction concepts.
- Offer challenge problems for advanced students (e.g., introducing mixed numbers).
- Use visual aids and interactive activities to engage all learning styles.
This lesson effectively uses co-teaching strategies to maximize student engagement and comprehension of fractions. By implementing these collaborative techniques, educators can create an inclusive and supportive learning environment where every student has the opportunity to succeed. With thoughtful planning and execution, co-teachers can build a classroom that not only strengthens mathematical understanding but also fosters a spirit of teamwork and shared responsibility for learning.
