discussed. It’s great to know that all of you remembered our lesson from our last meeting. Are you all excited to know what our next topic is all about? B.2 Motivation Alright, but before I introduce you, class, to our next lesson, Let’s first have an energizer to boost your mind, soul, and body. Please all stand up and group yourselves into three. So we will do the "Triangle Dance" and follow the steps by watching the video that I will be presenting. Are you ready, class? (Triangle Dance Video) Did you enjoy the triangle dance class? Okay, very good. Please all sit down. C. Developmental Activities C.1 Activity Before we formally proceed with our new lesson, let’s first have an activity. This activity is entitled "Scavenger Hunt." You will group yourself into 5 and try to find as many triangles as you can in just 5 minutes. It can be a triangle object or an image. The group that has the highest number of found triangles is our scavenger hunt winners and will receive 5 extra points for the assessment later. Are you all ready, class? The game begins in 3, 2, 1, Go! (After 5 Minutes) Let’s announce the winner. So the winner for the “Scavenger Hunt Game” is Group _________________. Let’s give them a Good Job Clap. C.2 ANALYSIS Did you enjoy the activity? That’s good to hear. ● How were you able to easily find different triangle objects and images? ● What have you noticed with the different triangle objects that you have found? ● Do they all have the same appearance? Alright, so all of your objects or images that you have shown to me are examples of triangles, but they do not have the same appearance. C.3 ABSTRACTION So, now we will discuss triangles, its definition and also the different types of triangle.

Another, yes Ms. ____________. Very good class. So now we'll have an activity to see if you really understand our lesson for today. C.4 APPLICATION This activity is called "Memory Wheels of Triangle." This activity is a group collaboration with your group mates. I want you to create a triangle memory wheel by illustrating the various types of triangles based on the length of the sides and internal angles. It's a two-sided wheel. The front face of the wheel is simply an illustration of the various types of triangles, whereas the back face of the wheel is an illustration of real-life examples of those various types of triangles. This is the example image of the Memory Wheels of Triangle. And this is the rubric of our second group activity: Did you enjoy our activity today? Is it useful to you, class, in remembering the different types of triangles?

I hope that by doing this activity, you will be able to identify the type of triangle you will see around your house, while walking around our neighborhood, or in other places. Alright, is there any question, class? Any clarifications? If none, get your activity notebook and answer this assessment. C.5 ASSESSMENT Matching Type: Match column A with the corresponding item in column B. Write the letter of your answer in the space provided. Column A
