- 16. Class, find the answer to the following multi operation mathematical expression by connecting the expression in column A to the corresponding answer in column B.
- 17. A B ( 3 ) ( 8 ) – ( 1 4 + 1 0 ) ( 2 + 6 ) ( 2 - 3 ) ( 2 ) ( 3 ) + 4 - 5 ( 2 + 6 ) ( 2 ) – ( - 4 ) ( 2 ) ( 3 ) / ( 3 - 1 ) ( 4 + 2 + ( 2 4 / 6 ) ) 2
- 18. EXPECTED ANSWERS
- 19. A B ( 3 ) ( 8 ) – ( 1 4 + 1 0 ) 5 ( 2 + 6 ) ( 2 - 3 ) 1 0 0 ( 2 ) ( 3 ) + 4 - 5 - 8 ( 2 + 6 ) ( 2 ) – ( - 4 ) 3 ( 2 ) ( 3 ) / ( 3 - 1 ) 2 0 ( 4 + 2 + ( 2 4 / 6 ) ) 2 0
- 21. Now tell me, how do we solve multi operation mathematical expression?
- 22. Sir we solve multi operation mathematical expression by following the rules of PEMDAS.
- 23. Very good.
- 24. And what does PEMDAS stand for?
- 26. That is correct! We solve multi operation expression by following the operation order of Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction.
- 27. Class, where do we usually hear the word substitution?
- 28. Sir we hear substitution in basketball, volleyball, etc...
- 29. And how do we substitute in basketball?
- 30. Sir the player is replaced by another player.
- 31. That’s right.
- 32. Now class, we will be having an activity called “Sub me in”.
- 33. Let A=1 H=8 O=15 V=22 B=2 I= 9 P= 16 W=23 C=3 J=10 Q=17 X=24 D=4 K=11 R=18 Y=25 E=5 L=12 S=19 Z=26 F=6 M=13 T=20 G=7 N=14 U=21
- 34. Find the equivalent value of the given words by substituting the numerical value above to each letter of the word and adding all the numerical digits. For example : H U M B L E 8 + 21 + 13 + 2 + 12 + 5 = 61
- 35. Do you get it class?
- 36. YES SIR !!!!
- 37. Are you ready class?
- 38. YES SIR !!!!
- 40. K N O W L E D G E 11 + 14 + 15 + 23 + 12 + 5 + 4 + 7 + 5 = 96
- 41. H A R D W O R K 8 + 1 + 18 + 4 + 23 + 15 + 18 + 11 = 98
- 42. A T T I T U D E 1 + 20 + 20 + 9 + 20 + 21 + 4 + 5 = 100
- 43. Very good class, does everyone have the same answers?
- 44. YES SIR !!!!
- 46. What did we do in our activity?
- 47. Sir we find the numerical value of the given words.
- 48. Correct. And how did we find the value of the given words?
- 49. Sir we substitute the corresponding value in each letter.
- 50. And then what’s next
- 51. Sir we perform the indicated operation, we add all the value.
- 52. Very good.
- 53. When a number is substituted or replace for the variable in a given algebraic expression, the expression takes a numerical value. And finding the value is what we call “Evaluating the Algebraic Expression”.
- 54. Let’s do this example.
- 55. PRESENTATION
- 56. Evaluate 6x2 + 3 when a. x = 0 b. x = -2
- 57. For letter a, how do we evaluate? What should we do first?
- 58. Sir we substitute the given value of x in the equation.
- 59. Correct. Can someone show us how to substitute the value of x in our equation?
- 60. Sir, we can substitute the value of x as 6(0)2 + 3
- 61. Very good.
- 62. Now what is the next step?
- 63. We perform the indicated operations.
- 64. Since we got here a multi operation equation, what should we do?
- 65. Sir we follow the rules of PEMDAS.
- 66. Excellent! Can someone demonstrate on how to apply the rules of PEMDAS in our equation?
- 67. 6x2 + 3 = 6(-2)2 + 3 = 6(4) + 3 = 24 + 3 = 27
- 68. That is correct! Now for letter b, x = -2. Who would like to try following the same steps?
- 69. 6x2 + 3 = 6(0)2 + 3 = 6(0) + 3 = 0 + 3 = 3
- 70. Very good.
- 71. Now class, in evaluating algebraic expressions, what are the steps that we need to follow?
- 72. 1. Substitute the given value to the variable. 2. Perform the indicated operation by following the rules of PEMDAS.
- 73. Very good.
- 74. APPLICATION
- 75. Now that you already know how to evaluate algebraic expressions, we will be having a group activity. I will divide you into two groups. Each group will choose their leaders.
- 76. The leader will be the one who can ask me about the activity and he is also responsible for dividing the tasks between the members of the group.
- 77. Each group will be given an activity envelope where you will find the materials for the activity and the expressions that your group will be going to evaluate.
- 80. x x2 – 7x + 12 0 1 -2 4 Students, solve these questions.
- 81. x x2 – 7x + 12 0 12 1 20 -2 2 4 0 Raise your hand if you got right answers.
- 83. 1. Students are able to Identify the steps in evaluating algebraic expressions 2. Students are able to Apply the steps in evaluating algebraic expressions 3. Students have shown appreciation in working with group activity Real Learning Outcomes
