PYTHAGREAN THEORM
|
|
|
WHAT IS THE THIRD DESRIPTOR
|
RECOGNIZE A VARITY OF TWO-DIMENSIONAL REPRESENTTIONS OF PARTS OF THREE DIMENSIONAL FIGURES

|
CONCEPTS OF DIRECT MEASUREMENT-APPRIOATE UNITS OF MEASURE WITH CONVERSION RATES, TEMPERATURE,:
|
CELSISUS BOTH IN DEGREES
F=9/5(C) + 32 C=5/9(F-32) |
|
|
|
CONCEPTS OF DIRECT MEASUREMENT: WEIGHT
|
TONS, POUNDS, ONCES, KILOGRAMS, GRAMS, CENTIGRAMS
TON=2000 PDS 1 POUND=16OZ 1 KG=1000 GRAMS 1 GRAM=100 CG |

CONCEPTS OF DIRECT -AREA
SQUARE UNITS |
SQUARE UNITS
Surface Area of a Cube = 6 a 2 Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides) b is the shape of the ends) Surface Area = Lateral area + Area of two ends (Lateral area) = (perimeter of shape b) * L Surface Area = (perimeter of shape b) * L+ 2*(Area of shape b) Surface Area of a Sphere = 4 pi r 2 (r is radius of circle) Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h |

CONCEPTS OF DIRECT MEASUREMENT-CAPACITY
|
CAPACITY
1=GALLON=4 QTS 1 QUART=2 PINTS 1 CUP=8 ONCES 1 LITER=1000 ML 1 PINT =2 CUPS |
1=GALLON=4 QTS
1 QUART=2 PINTS 1 CUP=8 ONCES 1 LITER=1000 ML 1 PINT =2 CUPS |

|
PERCENT OF ERROR DETERMINE THIS BY FINDING THE RATIO OF THE AMOUNT OF ERROR TO THE CORRECT MEASURE
|
EX: A STUDENT MEASURES THE ANGLES OF QUADILATERAL WHITH A PROTRACTOR AND FINDS THAT THE SUM OF THE ANGLES IS 354 DEGREES, HIS PERCENT OF ERROR CAN BE FOUND BY DOING TH E FOLLOWING 360 -354/360=6/360 =1.67%
|
O.167 CAN BE CONVERTED TO 1.67%
|
|
|
DIMENSIONAL ANLAYSIS
|
THIS IS A TECHNIQUE TO CONVERT MEASURES BY USING FORMS OF ONE. EXAMPLE: JUST LIKE NUMBERS WILL DO WHEN MULTIPLYING FRACTINSCONVERT THE AGE OF A 21 YERA OLD TO SECONDS:
21 YEARS/1* 365 DAYS/1 DAY * 24 HOURS/1DAY* 60 MIN/1 HOURS* 60 SECONDS/ 1MIN=662,256,000-NOTICE THAT EACH FRACTIION IS A FROM O FTHE NUMBER ONE. aLSO NOTICE THAT UNITS "CANCEL" OUT |
