Learning Competency Determines geometric means and nth term of a geometric sequence (M10AL - Ie – 1) Learning Objectives At the end of the lesson, the student will be able to: 1. Defines a geometric mean in a geometric sequence. 2. Finds the geometric mean of a given geometric sequence. 3. Demonstrates cooperation during group activities in determining the geometric mean of a given geometric sequence. Geometric Sequence Geometric Means

Note to the Teacher:  Divide the students into six (6) groups.  (The number of groups depend on the number of students)  The teacher should prepare the materials of the game before the class. (Refer to Attachment 4 for the pictures.)

 Tell to the student that as a review, they will play a game.  Ask them if they are familiar with the game “4 Pics 1 Word”  The game contains the following:

(Expected Answer:Flower)

(Expected Answer: Pineapple)

(Expected Answer: Cellipede)

  

(Expected Answer: Pattern) The teacher will show the pictures one at a time, then ask the group to identify the word presented by the picture shown. Tell the students that the group who can guess the correct answer will have one point. The first group who will get three points will

be declared as the winner. Guide Questions: 1. Did you enjoy the game? (Expected Answer: Yes) 2. What is common between the pictures presented? (Expected Answer: The pictures show patterns.) 3. How are we going to relate it to our previous lesson? (Expected Answer: The terms in a geometric sequence is related to the preceding term through a definite pattern.)

B. Establishing a purpose for the lesson

4. What is the formula in finding the nth term of a geometric sequence? (Expected Answer: an = a1rn-1) ACTIVITY 1  Since you already know how to find the nth term of a geometric sequence, we will have an activity.  With the same group, an activity sheet which contains the following will be given to them. Guide Questions: 1. How did you find the activity? (Expected Answer: Answers may vary) 2. How did you find the common ratio? (Expected Answer: We get the common ratio by dividing the second term to the first term, third term to the second term, and so on.) 3. How did you find the next terms? The missing terms? (Expected Answer: The next terms and the missing terms were found by using the geometric formula, an = a1rn-1) 4. So what is the world’s fastest insect? (Expected Answer: Dragonfly)

C. Presenting examples of the new lesson

ACTIVITY 2 Direction: Find the missing terms in each geometric sequence. 1. 3, 12, 48, __, __ (Expected Answer: 192, 768) 2. __, __, 32, 64, 128, ...

(Expected Answer: 8, 16) 3. 120, 60, 30, __, __, __ (Expected Answer: 15, 15/2, 15/4) 4. 5, __, 20, 40, __, __ (Expected Answer: 10, 80, 160) 5. __, 4, 12, 36, __, __ (Expected Answer: 4/3, 108, 324) 6. –2, __, __, –16 –32 –64 (Expected Answer: -4, -8) 7. 256, __, __, –32 16, ... (Expected Answer: -128, 64) 8. 27, 9, __, __, 1/3 (Expected Answer: 3, 1) 9. ___, 1, 4 __, 64, 256 (Expected Answer: 1/4, 16) 10. 5x2 ,__, 5x6 , 5x8 __ , ... (Expected Answer: 5x4, 5x10) Were you able to answer the activity? (Expected Answer: Yes) Which item in the activity did you find challenging? (Expected Answer: Answers may vary) Let us now discuss how to find the geometric means between terms of a geometric sequence. D. Discussing and Practicing new concepts

The teacher discusses the definition and other concepts of geometric mean. Inserting a certain number of terms between two given terms of a geometric sequence is an interesting activity in studying geometric sequences. In general, the terms between any two nonsuccessive terms in a geometric sequence are called geometric means. If the numbers a1, a2, a3…, an form a geometric sequence, the numbers a 2, a3…, an-1 are called geometric means between a1 and an. Remember: A geometric mean is a number inserted between two given numbers so that the terms form a geometric sequence....
