15. ENTRY BEHAVIOR TESTING

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

20. Very well done
students.

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?

25. Parenthesis, Exponent,
Multiplication,
Division, Addition,
Subtraction.

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 !!!!

39. KNOWLDEGE

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 !!!!

45. ANNOUNCEMENT OF TOPIC

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.

79. Understanding Level Testing
