6th GRADE NEWEST NOTES (Beyond 2016): Measurement


Page 44 Measurement – A description that includes a number and a unit, such as 5 seconds or 25 feet.

Page 44 Quantitative (extension) – Relates to descriptive information that is expressed as a quantity or number. Example: There were 11 fish in the aquarium

Page 44 Qualitative (extension)- Relates to descriptive information that is NOT expressed as a number. Example: The fish in the aquarium was yellow.

Page 50 Accuracy – Compares a measured value of a property with the standard value accepted for that property. (The smaller the difference between the standard value, the greater the accuracy).

Page 50 Precision – The exactness of measurement when measurement is repeated.

Page 62 Range- The difference between the smallest number and largest number in a set of data.

Page 63 Mean - The ‘average’. In other words, the sum of all values in a data set divided by the number of items in the data set. EXAMPLE: If the numbers are 3,4,5,6,7,8,9, the average would be 6. All numbers were added up and equal 42. 42 divided by 7 (total numbers) = 6

Page 63 Median - The ‘middle’ number in an ordered data set. EXAMPLE: If the numbers are 3,4,5,6,7,8,9, the ‘median’ would be 6. The number 6 is right in the middle.

Page 63 Mode – The ‘mode’ is the number or numbers that occur the MOST OFTEN. EXAMPLE: If the numbers are 5,6,7,7,7,8 then the mode is 7 because it occurs the MOST OFTEN.

***Other important terms to know for MEASUREMENT

Mass – The amount of matter in an object (think atoms packed together)

Time- A certain point where an event is said to have occurred, OR a designated point between 2 events

Position- Location

Volume – The amount of space that an object takes up

Weight – The pull of gravity on an object’s mass (The more mass an object has, the greater the pull of gravity on it). More mass = more weight

Length – The measure of the extent of something at its longest dimension

Temperature - The degree of intensity of heat present in a substance or object

Density - The amount of matter per unit of volume  (DENSITY = MASS divided by VOLUME)


MASS is measured in GRAMS (G)

VOLUME is measured in LITERS (We have measured it in cubic centimeters CM3….and liquid in MILLILITERS ML. A milliliter is 1/1000 of a liter

LENGTH is measured in METERS (We have used centimeters quite a bit. A centimeter is 1/100 of a meter)


KILO means 1,000

HECTO means 100

DEKA means 10

GRAMS, LITERS, and METERS are the BASIC UNITS of measure

DECI means 1/10 or .1

CENTI means 1/100 or .01

MILLI means 1/1000 or .001
