Perimeter
 Measure of the distance around a
figure (polygon) made up of straight
lines called sides (s, or l & w)
 Square, triangle, rectangle, trapezoid,
etc. or an irregular 2-D (flat) multisided shape.
Circle Perimeter?
 If the shape has curved lines instead
of straight we call it Circumference.
 Use radius (r)- distance from the center
to the edge of the circle
 diameter (d) – distance across the circle
passing through the center
 d = 2r or r = ½ d
Units
 Standard or metric
 Measurement of the side or distance
 Perimeter and circumference
Square units
 Area – measure of a shape’s (2-D Flat
figures) surface, space inside the
perimeter
 Why do we call it “square”?
?
Area
 PSSA Formula Sheet
 2-D figures – Square, parallelogram,
rectangle, triangle, trapezoid, circle,
and regular & irregular polygons
How do you find area of a
figure that doesn’t have a
formula?
Check-up – Perimeter,
Circumference and Area
 Handout of examples
 Lesson Practice: Perimeter,
Circumference, & Area
Calculating Surface Area
 Some formulas – cube, rectangular
prism, sphere, & cylinder
 No Formula?
 Find area of each face and add to find
the total surface area
What unit is used for Surface Area?
 Area of each shape that makes up a
3-D solid
 how much exposed area a solid object
has
 Answer: Square units
Check-up – Surface Area
 Handout of examples
 Lesson Practice – Surface Area
Cubic Units
 Volume: how much three-dimensional
(3-D) space a solid occupies
 Why do we call it “Cubic”?
?
Volume Formulas
 PSSA Formula sheet
 Prism, Cone, Pyramid, cylinder (many
types), & sphere
Check-up - Volume
 Handout of examples
 Lesson Practice - Volume
More Practice – if you need it
 Measuring Around
 What happened when Orgo tore up a
PUZZLE Book?
 Surface Area of Rectangular Prisms
 Comparing Volumes
Ticket out the Door
 Post-Test – same as Pre-test???
