How to Write a Lesson Plan – The 3Is Format


This blog post is a transcript of our YouTube video How to Write a Lesson Plan – The 3Is Format.

They say that inside the classroom the teacher is the captain of the ship. As captain, he/she should have a map to help lead his/her passengers—the students—to their destination safely and surely. In other words, a teacher must have a Lesson Plan in order to make sure that the students learn the lessons.

But how does a teacher make a lesson plan?

Hello, dear teachers and teachers-to-be!

In this 3-part video series, we will discuss how to write a lesson plan using the different lesson plan formats.

In this first video, we will write the Objectives, Subject Matter and Procedure of the lesson plan using the 3Is format.

In the second video, using the same Objectives and Subject Matter, we will be following the 4As format for the Procedure instead of the 3Is.

While in the third video, we will be applying the 5Es format and end by writing the lesson plan’s Evaluation and Assignment.

Overwhelmed? Don’t worry! I’ll be guiding you through these different parts with examples. Now without further ado, let’s get started!

A lesson plan is a detailed description of how the teacher will deliver a lesson or guide his/her students’ learning.

Although the format of a lesson plan may vary from teacher to teacher, or from school to school, here are the three most commonly used ones: the 3Is (or Introduction, Interaction and Integration), the 4As (Activity, Analysis, Abstraction and Application), and the 5Es (Engage, Explore, Explain, Elaborate, Evaluate).


As with any plan, the first part of a lesson plan is the Objectives.

The Objectives section describes what the students are supposed to learn at the end of the class or lesson.

For example:
I. Objectives
At the end of the lesson, the students will be able to:
  1. construct questions answerable by yes/no, and
  2. transform sentences into questions answerable by yes/no

Following the Objectives is the Subject Matter.

This section contains the Topic that is going to be discussed and the Materials and References that are going to be used in the lesson.

For example:
II. Subject Matter
Topic: Yes/No question
Materials: pictures, PowerPoint presentation, laptop, paper, marker, etc.
References: A Brown, Intensive English 8, pp. 32-33

A tip: Don’t forget to leave a space between the parts of your lesson plan. That way your sections will look clearer and your overall lesson plan more professional.

III. Procedure
The next part of a lesson plan is the Procedure.

This is where we will use one of the three lesson plan formats shown earlier. As mentioned, in this video we will be using the 3Is format. But before we do, we will first discuss each of the components of the 3Is (Introduction, Interaction and Integration), then provide examples following the Objectives and Topic set earlier in this video.

A quick note: In writing the Procedure of your lesson plan, number your items or use bullet points. The examples here use the third person pronoun “she”, because it assumes that the teacher is a woman.





With that, I hope you now have an idea of how to make the first parts of a lesson plan using the 3Is.

It’s very important to start with this format first before proceeding to the more complex ones. The 3Is provides the basic structure from which the other formats are derived. The first two parts of the 4As and the 5Es, for example, are derived from the Introduction component of the 3Is.

In our next video, following the same Objectives and Subject Matter, we will be using 4 As format for the lesson plan’s Procedure.
