DETAILED LESSON PLAN IN MATH 4 I. OBJECTIVES At the end of the lesson, the pupils are expected to achieve at least a 75% proficiency level in the following behavior: Cognitive: Visualize the perimeter of any given plane figure in different situations; Psychomotor: Measure the perimeter of any given closed figure using appropriate tools; and Affective: Show accuracy in counting. II.SUBJECT MATTER Topics: Visualizing the Perimeter Reference: SDOIC Workbook, https://www.k5learning.com/worksheets/math/grade-2-geometry- perimeter-a.pdf, Materials: PPT, realia, pictures, tarpapel, show-me-board with marker and eraser, Group Activity cards, models, illustrations, etc. Values Focus: Appreciation and Cooperation Teacher's Activities Pupil’s Activities III.LEARNING EXPERIENCES A. Routine Activities 1.Greetings "Good morning, Class!" "Good morning, Teacher Kyla!" "How are you today?" "We are okay teacher!" "That is good to hear!" 2. Checking of Attendance "Before our lesson begin, let me know who did not attend on our class for today." "Group 1, did everyone attend in your group?" "Very good! Group 2, is everyone attend in the group?" "Yes, teacher!" "Yes teacher, we are complete" "Very good also, group 2. Group 3, did all of you also attend?" "Yes teacher, we are also complete" "Wow, you'll are very good. Now I want you to watch the video that I will play so that we can be lively and have an energy for our discussion for today, is that ok class?" "Yes, teacher!" B. Preparatory Activities 1.Drill "Okay class, we have an energy now for our discussion. So now, what do you think is a unit of measurement and measuring tool that is appropriate for the following. 1.distance between buildings 2. sides of a handkerchief 3. length of a safety pin (The students will participate) 4. length of a ballpen 5. edge of a table 6. sides of the blackboard 2. Motivation Show a plain handkerchief. What is the shape of these handkerchiefs? It’s square, Teacher! Do you carry your handkerchief every day? Sometimes teacher I carry my handkerchief, but sometimes I forgot it in our home! What are the uses of a handkerchief? The use of the handkerchief is to wipe the dirt’s or sweats of our face Teacher! What other shapes do you know aside from square? I know rectangle, circle, triangle or kite teacher! C. Lesson Proper 1. Presentation Study the figures. 2. Discussion How many sticks do you think are put around each closed figure? You can count the sticks around each figure to find the perimeter. In the figure A, how many sticks are in there? In figure A Teacher, there are 12 sticks. So, I think the perimeter is 12 units. Wow, very good! How about in Figure B, how many sticks are in there? In figure B Teacher, there are 12 sticks. So, I also think the perimeter is 12 units. Wow, you’re also very good! How about in the Figure C, how many sticks do you think are in there? In figure C, there are 6 sticks Teacher. So, the perimeter is 6 units because there are 6 sticks. You’re correct. How about in the Figure D, how many sticks are in there? In figure D Teacher, it has 4 sticks. So, the perimeter is 4 units. Wow, very good. How about in the Figure E, the last shape that we have? If you notice the measures of all sides of a polygon are added to find its perimeter. Therefore, perimeter is the distance around a polygon. Find the perimeter of the following figures by counting the squares. In figure E Teacher there are 13 sticks. So, the perimeter is 13 units. 3. Assessment Find the perimeter of the figure in each grid. 4. Application After our discussion, we can now have a little activity that can know if you learn something today, Yes, Teacher. understand class? Do what is being asked using a paper grid. 1. Draw a square with a perimeter of 12 units. 2. Draw a rectangle with a length of 6 units and width of 4 units. 3. Draw a trapezoid with a height of 7 units and bases of 3 units and 5 units. 4. Draw a parallelogram with length of 5 units and width of 4 units. 5. Draw a rhombus with a side of 16 units. 5. Generalization The perimeter of a shape is the measurement of the total length of the outline of the shape. Do you Yes, Teacher! understand, class? IV.EVALUATION And now that we finish our discussion, let’s have some activity that I know you can enjoy. If each square is 1 cm by 1 cm (shown below), find the perimeter for the shapes shown below.
