Development (20 - 25 minutes)

1. Difference of Squares: (5 - 7 minutes)

   1.1. Theory Presentation: The teacher starts by explaining the Difference of Squares pattern. If an algebraic expression can be written as the difference of two squares, then it can be factored into the product of the sum and difference of those two terms.

   1.2. Demonstration: The teacher demonstrates this using an example, such as x^2 - 9 = (x + 3)(x - 3). This is followed by a detailed step-by-step explanation of how the original expression is factored.

   1.3. Practice: The students are then given a few problems to solve on their own using the Difference of Squares technique. The teacher walks around to offer help and ensure that all students understand.

2. Sum and Difference of Cubes: (5 - 7 minutes)

   2.1. Theory Presentation: The teacher continues by explaining the Sum and Difference of Cubes pattern. If an algebraic expression can be written as the sum or difference of two cubes, then it can be factored into the product of the sum or difference of those two terms.

   2.2. Demonstration: The teacher demonstrates this using an example, such as x^3 + 8 = (x + 2)(x^2 - 2x + 4). This is followed by a detailed step-by-step explanation of how the original expression is factored.

   2.3. Practice: The students are then given a few problems to solve on their own, using the Sum and Difference of Cubes technique. The teacher walks around to offer help and ensure that all students understand.

3. Perfect Square Trinomials: (5 - 7 minutes)

   3.1. Theory Presentation: The teacher moves on to the Perfect Square Trinomials pattern. If a trinomial is the square of a binomial, then it can be factored into the product of that binomial multiplied by itself.

   3.2. Demonstration: The teacher demonstrates this using an example, such as x^2 + 6x + 9 = (x + 3)(x + 3). This is followed by a detailed step-by-step explanation of how the original expression is factored.

   3.3. Practice: The students are then given a few problems to solve on their own, using the Perfect Square Trinomials technique. The teacher walks around to offer help and ensure that all students understand.

4. Comparative Analysis and Application: (5 minutes)

   4.1. Comparative Analysis: The teacher revisits each factoring pattern, highlighting the differences and similarities between them. This helps students to understand when each pattern is most appropriate.

   4.2. Application: The teacher presents a new set of problems that involve a mix of the Special Factoring Patterns. Students are asked to identify the pattern in each problem and apply the corresponding technique to factor the expression. This exercise tests the students' understanding of the different patterns and their ability to apply them correctly.

By the end of the development stage, students should have a solid understanding of the Special Factoring Patterns and be able to identify when and how to apply each pattern. The teacher should ensure that all students have had the opportunity to practice and apply the factoring patterns, and should offer additional help or explanation where needed.
