Measurement
Customary measurement of
length, mass and volume
Metric measurement of
length, mass and volume
Customary Measurements


A system of measurement used in the
United States used to describe how
long, how heavy, or how big
something is
Examples:
inches, feet, yards, miles
Customary Measurement
of length
12 inches = 1 foot
3 feet = 1 yard
36 inches = 1 yard
5,280 feet = 1 mile
Customary Measurements
of weight/mass
16 ounces (0z) = 1 pound (lb)
2000 pounds (lbs) = 1 ton (T)
Customary Measurement
of Capacity/ Volume

Capacity/volume: how much a
container can hold
8 fl oz = 1 cup
2 cups = 1 pint
2 pints = 1 quart
2 quarts = 1/2 gallon
4 quarts = 1 gallon
Metric Measurements

A system of measurement used in
most other countries to measure how
long, how heavy, or how big
something is
Metric Measurements of
Length

10 millimeters (mm) = 1 centimeter
(cm)

100 centimeters = 1 meter (m)

1,000 meters = 1 kilometer (km)
Metric Measurements of
Weight/Mass

1,000 milligrams (mg) = 1 gram (g)

1,000 grams = 1 kilogram (kg)
Metric Measurements of
Capacity/ Volume


The milliliter (mL) is a metric unit used
to measure the capacities of small
containers. Example= a dropper
The liter (L) is equal to 1,000 mL, so it
is used to measure the capacities of
larger containers. Example= a bottle
of soda

Quadrilaterals,
Plotting coordinates on a grid
Perimeter and Area
Volume of rectangular prisms
Quadrilaterals


Quadrilaterals are any four-sided
shapes. They must have straight lines
and be two-dimensional.
Examples: squares, rectangles,
rhombuses, parallelograms,
trapezoids, kites
More about quadrilaterals
The Square


The square has four equal sides.
All angles of a square equal 90
degrees.
The Rectangle


The Rectangle has four right angles
and two sets of parallel lines.
Not all sides are equal to each other.
The Rhombus



A rhombus is a four-sided shape where all
sides have equal length.
Also opposite sides are
parallel and opposite angles are equal.
A rhombus is sometimes called a diamond.
The Parallelogram


A parallelogram has opposite sides
parallel and equal in length.
Also opposite angles are equal.
Plotting Coordinates
Plotting Coordinates
(continued)



(x,y)
Find the point on the x-axis first
(horizontal / left to right)
Then find the point on the y-axis and
graph (vertical / up and down)
Finding the Perimeter

To find the perimeter of most
two-dimensional shapes,
just add up the sides
Area


Area is the measurement of a shape’s
surface.
Remember that units are squared for
area!!
Finding the Area of a
Square




To find the area of a square,
multiply the length times the width
A= (l)(w)
A=2x2
A = 4 cm²
Finding the area of
rectangles


To find the area of a rectangle, just
multiply the length and the width.
A= (l)(w)
Volume


Volume is the amount of space that a
substance or object occupies, or that
is enclosed within a container
Remember that the units of volume
are cubed (example: inches^3)
because it measures the capacity of a
3-dimensional figure!
Finding the Volume of
Rectangular Prisms




To find the volume of a rectangular
prism, multiply the length by the width
and by the height of the figure
V = (l)(w)(h)
V=6x3x4
V = 72 cm³
