Introduction (10 - 15 minutes)

1. Teacher's Introduction:

   • The teacher begins by reminding the students of the basic concepts of fractions that they have learned in the previous classes. This includes the definition of fractions and how they represent parts of a whole.
   • The teacher then presents two problem situations to the students:
     1. "If I have a pizza and I eat 1/4 of it, and my friend eats 2/4 of it, how much of the pizza have we eaten in total?"
     2. "If I have 3/5 of a chocolate bar and I give my friend 1/5 of it, how much of the chocolate bar do I have left?"
   • The teacher then explains that the students will be learning how to add and subtract fractions to solve these types of problems.

2. Contextualizing the Topic:

   • The teacher explains the importance of learning how to add and subtract fractions. They can use examples from real-life situations, such as cooking (where fractions are commonly used in recipes) or construction (where fractions are often used in measurements).
   • The teacher also points out that understanding fractions is a fundamental skill in mathematics and will be used in more advanced concepts in the future.

3. Grabbing the Students' Attention:

   • The teacher shares a fun fact about fractions, such as the fact that the word 'fraction' comes from the Latin word 'fractus', which means 'broken'. This is because a fraction represents a broken or divided whole.
   • The teacher then presents a problem for the students to think about: "If I have a bag of Skittles and there are 20 red Skittles and 30 blue Skittles, what fraction of the Skittles are red and what fraction are blue?" The teacher encourages the students to think about how they could represent the fractions in this problem.

4. Transition to the Lesson:

   • The teacher concludes the introduction by telling the students that they will now be learning how to add and subtract fractions, which will help them solve the problems presented at the beginning of the class and many other real-world problems.

Development

Pre-Class Activities (10 - 15 minutes)

1. Reading Assignment: The students are provided with a short reading assignment that introduces the concept of fractions and explains how to add and subtract fractions with like and unlike denominators. The reading material includes simple exercises for the students to practice.
2. Video Tutorial: The students are assigned a video tutorial to watch at home. The video explains the concept of fractions in a visual and engaging manner, and provides step-by-step instructions on how to add and subtract fractions.

In-Class Activities (20 - 25 minutes)

Activity 1: Fraction Pizza Party

1. Materials Required: Paper, color pencils, pair of dice, Fraction Pizza Party template (a grid with several pizza slices each split into different fractions, such as 1/2, 1/3, 1/4, etc.), a fraction strip (a strip of paper with different fractions marked), and Fraction Pizza Party question cards (a set of cards with addition and subtraction problems involving different fractions).
2. Instructions:
   1. The teacher divides the class into small groups and hands out the materials.
   2. Each group receives a Fraction Pizza Party template and color pencils.
   3. Using a pair of dice, the groups roll to determine the numerator and denominator for a fraction to draw on their pizza slice.
   4. The groups then draw the fraction on their pizza slice on the template. The fraction strip can be used as a guide.
   5. The teacher then draws a question card from the deck and reads the problem out loud.
   6. The groups discuss and try to solve the problem using their fraction pizza slice as a visual aid. The first group to solve the problem correctly wins the round.
   7. The game is repeated for several rounds, allowing different groups to win and practice different problems.

Activity 2: Fraction Skittles Sorting

1. Materials Required: Several bags of Skittles (each with different colors), a Skittles Fraction Sorting worksheet (a table with columns for each color of Skittles and rows for different fractions), and a timer.
2. Instructions:
   1. The teacher divides the class into small groups and hands out the materials.
   2. Each group receives a bag of Skittles and a Skittles Fraction Sorting worksheet.
   3. The teacher starts the timer for a set period (3 minutes, for example).
   4. The groups work together to sort their Skittles into the different fractions on the worksheet. For example, if a group has 10 red and 10 blue Skittles, they would sort them as 1/2 red and 1/2 blue.
   5. The group that sorts the most Skittles correctly within the time limit wins the round.
   6. The game is repeated for several rounds, allowing different groups to win and practice different fractions.

At the end of the activities, the teacher and students discuss the solutions, clarify doubts, and reinforce the concepts learned.

Feedback (5 - 10 minutes)

1. Group Discussion:

   • The teacher facilitates a group discussion where each group shares their solutions or conclusions from the in-class activities. This allows the students to learn from each other and to see different approaches to the same problem.
   • Each group is given up to 3 minutes to present their work. The teacher uses this time to assess the students' understanding of the concepts and to provide feedback on their solutions.

2. Connection to Theory:
