25. ONE POSSIBLE REASON WHY ADULT LEARNERS STRUGGLE WITH SOLVING EQUATIONS

26. A Tale of Two Minds

27. A common learning theory proposes that the minds of our adult learners are like swiss cheese.

29. As instructors we find out where the holes in their learning are, then simply plug the holes.

30. Exponents

31. Square Roots

32. The problem with this theory is that if we do not evaluate the holes correctly we can create cognitive overload.

33. ….And, the concepts are detached from each other.

34. A second theory proposes that our adult learners have minds that are similar to Legos.

36. Our minds learn best when they are building concept upon concept…

38. ….and they are attached to each other.

39. The Brownie Story

41. 6 Simple Rules to solve equations

42. 1 st Simple Rule The Value of Unknown

43. The goal of algebra is to find the value of an unknown. 1 st Simple Rule The Value of Unknown

44. X must be…

45. Isolated – like the Queen of England

46. X must be… Positive – not like Country and Western music Isolated – like the Queen of England

47. The answer needs to look like this:

48. X

49. Not like this: The answer needs to look like this: X

50. 2x Not like this: The answer needs to look like this: X

51. or2x Not like this: The answer needs to look like this: X

52. - xor2x Not like this: The answer needs to look like this: X

53. 2 nd Simple Rule Balance

54. A prerequisite for learning algebra is understanding balance. 2 nd Simple Rule Balance

55. You can do pretty much anything that you want to do to an equation, as long as you do it to both sides..

56. 3 = 3

57. Balanced

58. 3 = 3+1

59. 3 = 4 Unbalanced

60. 3 = 3+1

61. 3 = 3+11+

62. 4 = 4

63. Balanced

65. 4x

66. =

67. 8 =

70. 4

71. 4 =

72. 4 = 8

73. 4 = 8

74. 4 = 8

75. 4 = 8 4

76. 4 = 8 4

77. x = 8 4

78. x =2

79. 3 rd Simple Rule Distributive Property

80. If there are parentheses in an equation, then multiply across the parentheses distributing evenly. 3 rd Simple Rule Distributive Property

81. Kind of like one bowl of fruit with many people in which to distribute.

83. A banana to Tom

84. An apple to George A banana to Tom

85. An apple to George A banana to Tom An orange to Lebron

86. Using the Distributive Property Example: Find each product by using the distributive property to remove the parentheses. a.) 2(x + y) b.) 7(x + 2y – 5z) c.) – 4(3a – 3b – 10c)

87. Using the Distributive Property Example: Find each product by using the distributive property to remove the parentheses. a.) 2(x + y) b.) 7(x + 2y – 5z) c.) – 4(3a – 3b – 10c) a.) 2(x + y) = 2x + 2y

88. Using the Distributive Property Example: Find each product by using the distributive property to remove the parentheses. a.) 2(x + y) b.) 7(x + 2y – 5z) c.) – 4(3a – 3b – 10c) a.) 2(x + y) = 2x + 2y b.) 7(x + 2y – 5z) = 7x + 14y – 35z

89. Using the Distributive Property Example: Find each product by using the distributive property to remove the parentheses. a.) 2(x + y) b.) 7(x + 2y – 5z) c.) – 4(3a – 3b – 10c) a.) 2(x + y) = 2x + 2y b.) 7(x + 2y – 5z) = 7x + 14y – 35z c.) – 4(3a – 3b – 10c) = – 12a + 12b + 40c

90. 4 th Simple Rule Addition Property of Equality

91. 4 th Simple Rule Addition Property of Equality Move variables to one side of the fence (equal sign) and non- variables to the other side (making sure to change the sign if they cross over).

92. Much like corralling cattle and sheep.

94. 3x= 6

95. x +2=-4

96. 3x x +2=-4

97. 3x -x+2 = -4

98. 3x -x+2 = -4

99. 3x-x-2=-4

100. 5 th Simple Rule Like terms

101. 5 th Simple Rule Like terms Collect Like terms (same variables raised to the same power) by adding the numerical coefficients.

102. We cannot combine a chicken and a goat and create a Chickengoat Combining like terms

103. Or a Zonkey? Combining like terms

105. 6x 2 + 7x 2 19xy – 30xy 13xy 2 – 7x 2 y

106. Combining like terms 6x 2 + 7x 2 19xy – 30xy 13xy 2 – 7x 2 y 13x 2

107. Combining like terms 6x 2 + 7x 2 19xy – 30xy 13xy 2 – 7x 2 y 13x 2 – 11xy

108. Combining like terms 6x 2 + 7x 2 19xy – 30xy 13xy 2 – 7x 2 y 13x 2 – 11xy Can’t be combined (since the terms are not like terms)

109. 6 th Simple Rule Multiplication Property of Equality

110. 6 th Simple Rule Multiplication Property of Equality Divide (or multiply) both sides of an equation to get the variable isolated and positive.

111. 3x-x-2 = -4 2x = -6

112. 2x = -6 2 2 x=-3
