Introduction (10 - 12 minutes)

1. The teacher begins by reminding students of previously learned concepts related to fractions. This includes the idea that a fraction represents a part of a whole and that fractions can be greater, equal, or smaller than one. The teacher can ask questions to prompt students' memory, such as "What is a fraction?" and "How do we compare fractions?" (2 - 3 minutes)

2. The teacher then presents two problem situations to serve as a foundation for the lesson. These could be real-world examples that involve adding and subtracting fractions, such as dividing a cake between friends or combining ingredients in a recipe. The teacher uses these problems to demonstrate the importance of understanding how to add and subtract fractions. (2 - 3 minutes)

3. The teacher then contextualizes the importance of the subject by discussing real-world applications of adding and subtracting fractions. For example, the teacher can explain how bakers use fractions to adjust the size of their recipes, or how construction workers use fractions to measure materials. This helps students understand that the skills they are learning are not just theoretical, but also practical and applicable in their daily lives. (2 - 3 minutes)

4. The teacher introduces the topic of the day, adding and subtracting fractions. To grab students' attention and spark their interest, the teacher can share some fun facts or stories related to fractions. For instance, the teacher can tell the story of the Egyptian Pharaohs who used fractions over 4,000 years ago to divide their land. Alternatively, the teacher can share the fact that the word "fraction" comes from the Latin word "fractus," which means broken. This can be a starting point for a discussion on the historical and etymological aspects of fractions. (2 - 3 minutes)

5. To conclude the introduction, the teacher provides a brief overview of the lesson plan, outlining the objectives, activities, and assessments that will take place. The teacher also emphasizes the interactive and hands-on nature of the lesson, encouraging students to actively participate and engage with the material. (1 minute)

Development (20 - 25 minutes)

Activity 1: Fraction Tower Contest (10 - 12 minutes)

1. The teacher divides the class into small groups of 3-4 students. Each group is given a set of Fraction Tower Cubes (manipulatives that represent different fractions) and a task card.

2. The task card contains a series of addition and subtraction problems using fractions with like denominators. The goal of the game is for each group to correctly solve as many problems as they can within a specified time frame (around 8 minutes).

3. To solve the problems, students must use their Fraction Tower Cubes. They stack the cubes to represent the fractions in the problem, and then add or subtract the fractions by combining or removing cubes.

4. The teacher circulates around the room, observing the groups and providing assistance as needed. This could include prompting students to explain their solutions, offering hints if a group is struggling, or providing feedback on their work.

5. At the end of the time period, the teacher calls for a halt and each group counts the number of correctly solved problems. The group with the most correctly solved problems wins the contest.

6. The teacher then leads a class discussion, asking each group to share their most challenging problem and how they solved it. The teacher also addresses any common mistakes observed during the activity and provides additional explanations or examples as needed.

Activity 2: Common Denominator Relay (10 - 12 minutes)

1. The teacher again divides the class into small groups and assigns each group a problem on a worksheet. These problems involve fractions with unlike denominators.

2. The aim of the activity is for each group to find the common denominator for their set of fractions and then correctly add or subtract them. The first group to correctly solve their problem and cross the finish line in front of the class wins.

3. To solve the problem, each group member must complete a step of the process. One student finds the common denominator, the next adds or subtracts the fractions, and the third checks the answer.

4. The teacher acts as a referee, ensuring that each student completes their step before the group can move on. If a mistake is made, the group must go back and fix it before continuing.

5. After the race, the teacher facilitates a brief discussion, asking students about their strategies for finding the common denominators and solving the problems. The teacher also addresses any common challenges or misconceptions observed during the activity.

By the end of these hands-on activities, students should have a solid understanding of how to add and subtract fractions, both with like and unlike denominators. They will have also developed their problem-solving and collaborative skills, and seen firsthand how fractions are used in everyday life.

Feedback (5 - 7 minutes)

1. The teacher wraps up the hands-on activities and invites the students back to their seats. The teacher then initiates a group discussion, asking each group to share their solutions and the strategies they used to solve the problems. This helps to reinforce the concepts learned during the activities and allows students to learn from each other's approaches. (2 - 3 minutes)

2. The teacher then connects the outcomes of these discussions to the theoretical aspects of the lesson. For instance, the teacher can point out how using the Fraction Tower Cubes in the first activity mirrors the process of finding a common denominator in mathematical terms. The teacher can also highlight how the group work in both activities fosters collaboration, a key skill in mathematics and in life. (1 - 2 minutes)

3. Following the group discussions, the teacher facilitates a reflection session. The students are asked to think about and respond to questions like:

   • "What was the most important concept you learned today?"
   • "Which questions do you still have about adding and subtracting fractions?"
   • "How might you use what you learned today in real life?"
   • "What was the most challenging part of today's lesson and how did you overcome it?"

   The teacher encourages students to share their thoughts openly and without fear of judgment. This helps to create a supportive learning environment where students feel comfortable to express their ideas and concerns. (2 - 3 minutes)

4. To conclude the feedback stage, the teacher summarizes the main points of the lesson, emphasizing the importance of understanding how to add and subtract fractions correctly and the significance of using the right techniques. The teacher also addresses any remaining questions or concerns and provides further clarification if needed. (1 minute)

Conclusion (5 - 7 minutes)

1. The teacher begins the conclusion by summarizing the main points of the lesson. This includes a recap of what fractions are and how to add and subtract them. The teacher can use visual aids, such as a fraction wall or a diagram of the Fraction Tower Cubes, to help reinforce these concepts. The teacher also revisits the importance of keeping the denominator the same when adding or subtracting fractions with like denominators, and the process of finding a common denominator for fractions with unlike denominators. (2 - 3 minutes)

2. The teacher then explains how the lesson connected theory, practice, and real-life applications. This could include a discussion about how the hands-on activities helped students to visualize and understand the mathematical operations involved in adding and subtracting fractions. The teacher can also highlight the real-world examples used in the lesson, such as dividing a cake or combining ingredients in a recipe, and how these demonstrate the practical applications of the concept.
