46
YOURE THE STORYTELLER
  • CREATE A SITUATION FOR EACH EQUATION
  • SOLVE EACH EQUATION

47
RUNNING ON THE OVERLAND TRAIL
  • CHOOSE AND DEFINE A VARIABLE
  • WRITE AN EQUATION
  • SOLVE EACH EQUATION

48
LAMPPOST SHADOWS
  • ARE THESE TWO TRIANGLES SIMILAR?
  • WHAT EQUATION DID YOU USE?

49
THE MYSTERY BAGS GAME
  • IF YOU TAKE THE SAME AMOUNT OF WEIGHT FROM BOTH
    PANS, IS WHATS LEFT ON THE PANS ALWAYS BALANCED?

50
SUBSTITUTION AND EVALUATION
  • SUBSTITUTE IS THE STEP OF REPLACING THE VARIABLE
    WITH A NUMBER
  • EVALUATION IS THE STEP OF FINDING A SINGLE
    NUMBER FROM THE SUBST. STEP

51
LETTERS, NUMBERS, AND A STORY
  • ORDER OF OPERATIONS
  • PARAENTHESES
  • EXPONENTS
  • MULTIPLICATION OR DIVISION
  • ADDITION OR SUBTRACTION

52
CATCHING UP
  • HAS THE SWAYER FAMILY CAUGHT UP TO THE WAGON
    TRAIN AFTER 6 DAYS?

53
CATCHING UP
  • HAS THE SWAYER FAMILY CAUGHT UP TO THE WAGON
    TRAIN AFTER 15 DAYS?

54
CATCHING UP
  • HOW MANY DAYS DO YOU THINK IT WILL TAKE THE
    SWAYER FAMILY CAUGHT UP TO THE WAGON TRAIN?

55
MORE LETTERS, NUMBERS, AND MYSTERY BAGS
  • ORDER OF OPERATIONS
  • PARAENTHESES
  • EXPONENTS
  • MULTIPLICATION OR DIVISION
  • ADDITION OR SUBTRACTION

56
BACK TO THE LAKE
WHAT IS YOUR RULE FROM THE IN OUT TABLE?
  • D 6/n

57
LINE IT UP
  • WHAT KIND OF ALGEBRAIC EXPRESSION DO YOU THINK
    CAN BE USED TO REPRESENT ANY LINEAR FUNCTION?

y axb
58
WHOS RIGHT?
  • 2(X 1) OR 2X 2

59
A LOT OF CHANGING SIDES
  • MAKE AND LABEL A SKETCH OF THE LOT
  • USE THE VARIABLE X

60
A LOT OF CHANGING SIDES
  • WRITE AN EXPRESSION OF THE NEW LOT AS A PRODUCT
    OF ITS LENGTH AND WIDTH
  • WRITE AN EXPRESSION OF THE NEW AS A SUM OF
    SMALLER AREAS

61
WHY ARE THEY EQUIVALENT?
  • RANDY REPEATED ADDITION
  • SANDY SUBSTITUTION
  • DANDY DISTRIBUTE

62
DISTRIBUTING THE AREA
  • WRITE AS THE PRODUCT OF ITS LENGTH AND WIDTH
  • WRITE AS THE SUM OF TWO SMALLER AREAS

63
THE DISTRIBUTIVE PROPERTY AND MYSTERY LOTS
  • MULTIPLYING THROUGH
  • TAKING OUT A COMMON FACTOR

64
TAKING SOME OUT, PART I
  • A - ( B C) A - B - C

65
TAKING SOME OUT, PART II
  • A - ( B - C) A - B C

66
MORE SCRAMBLED EQUATIONS AND MYSTERY BAGS
  • UNCOMPLICATE EACH EQUATION BY SOLVING
  • SUBSTITUTE THE VALUE OF X BACK INTO THE EQUATION
    AS A CHECK

67
NEW FRIENDS VISIT YOUR HOME
  • DISTRIBUTE
  • COMBINE LIKE TERMS
  • ISOLATE THE VARIABLE TERM TO ONE SIDE
  • DIVIDE BOTH SIDES BY THE COEFFICIENT

68
FROM ONE VARIABLE TO TWO
  • SOLVING FOR Y IN TERMS OF X
  • ISOLATE THE Y TERM TO ONE SIDE
  • DIVIDE YS COEFFICIENT ON BOTH SIDES

69
GET IT STRAIGHT
  • HOW DO YOU CHANGE A LINEAR EQUATION IN ORDER TO
    CHANGE THE SLANT OF ITS GRAPH?

COEFFICIENT MULTIPLY OR DIVIDE
70
GET IT STRAIGHT
  • HOW DO WE CHANGE THE EQUATION IN ORDER TO SHIFT
    IT UP OR DOWN?

CONSTANT ADD OR SUBTRACT
71
GET IT STRAIGHT
  • WHEN ARE LINEAR FUNCTIONS MIRROR IMAGES OF ONE
    ANOTHER?

CONSTANT POSITIVE NEGATIVE
72
GET IT STRAIGHT
  • WHEN DO TWO LINEAR FUNCTIONS GIVE PARALLEL LINES?

COEFFICIENT SAME
73
GET IT STRAIGHT
  • WHEN DO TWO LINEAR FUNCTIONS GIVE PERPENDICULAR
    LINES?

COEFFICIENTNEGATIVE RECIPROCALS
74
GET IT STRAIGHT
  • WHAT LINEAR FUNCTIONS GIVE HORIZONTAL LINES?

Y
75
A DISTRIBUTIVE SUMMARY
  • DEFINE THE DISTRIBUTIVE PROPERTY IN YOUR OWN
    WORDS
  • INCLUDE AREA DIAGRAMS AND THE FOIL METHOD

76
ALL BY ITSELF
  • SOLVING FOR Y IN TERMS OF X
  • ISOLATE THE Y TERM TO ONE SIDE
  • DIVIDE YS COEFFICIENT ON BOTH SIDES

77
MORE VARIABLE SOLUTIONS
  • SOLVING FOR Y IN TERMS OF X
  • ISOLATE THE Y TERM TO ONE SIDE
  • DIVIDE YS COEFFICIENT ON BOTH SIDES

78
A MIXED BAG
  • SOLVING FOR A NUMERICAL SOLUTION
  • SOLVING FOR AN EXPRESSION

79
THE GRAPH SOLVES THE PROBLEM
  • UTILIZE THE TRACE BUTTON ON THE GRAPHING
    CALCULATOR

80
WHERES SPEEDY?
  • UTILIZE THE TRACE BUTTON ON THE GRAPHING
    CALCULATOR

81
TO THE RESCUE
  • N WHERE THE HELICOPTER FIRST DROPPED THE OBJECT
  • N 400FT
  • h(T) THE OBJECTS HEIGHT AFTER t SECONDS SINCE
    ITS BEEN DROPPED

82
TO THE RESCUE
  • N 400FT
  • h(T) THE OBJECTS HEIGHT
  • t SECONDS AFTER THE OBJECT HAS BEEN DROPPED

83
SWINGING PENDULUM
  • UTILIZE THE GRAPHING CALCULATORS TABLES

84
MYSTERY GRAPH
  • f(4)y, THAT IS WHAT IS Y WHEN x 4
  • f(x) 7, THAT IS WHAT IS X WHEN y 7

85
FUNCTIONING IN THE MATH WORLD
  • A FUNCTION CAN BE REPRESENTED IN FOUR WAYS
  • SITUATION
  • EQUATION
  • GRAPH
  • IN OUT TABLE

86
THE GRAPHING CALCULATOR SOLVER
  • THE GRAPH IS LIKE AN ANSWER KEY
  • UTILIZE THE TRACE BUTTON
  • THE TABLE IS LIKE AN ANSWER KEY
  • UTILIZE THE TABLES

87
A SOLVING SAMPLER
  • MYSTERY BAGS MODEL
  • UNSCRAMBLING EQUATIONS
  • GRAPHING
