Warm-up

1
Warm-up

• Pre-test

2
Perimeter, Area, Volume and Surface Area

• Review of vocabulary and formulas

3
Objectives

• Know the definitions of perimeter, area, volume
  and surface area
• Understand units, square units, and cubic units
  and how they relate to perimeter, area and volume
• Use formulas to calculate perimeter, area,
  volume, and surface area

4
Roll the Dice

• Roll the dice and define the geometry vocabulary
  word next to your number.

5
Dice Roll Number Match

• 11. Circle
• 12. Cube
• 13. Prism
• 14. Cone
• 15. Pyramid
• 16. Cylinder
• 17. Triangle
• 18. Trapezoid
• 19. Rectangle
• 20. Sphere

• 2. Circumference
• 3. Perimeter
• 4. Surface Area
• 5. Volume
• 6. Cubic Unit
• 7. Square Unit
• 8. Unit
• 9. Radius
• 10. Diameter

6
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) multi-sided shape.

7
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

8
Units

• Standard or metric
• Measurement of the side or distance
• Perimeter and circumference

9
Square units

• Area measure of a shapes (2-D Flat figures)
  surface, space inside the perimeter
• Why do we call it square?

?
10
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 doesnt
  have a formula?

11
Check-up Perimeter, Circumference and Area

• Handout of examples
• Lesson Practice Perimeter, Circumference, Area

12
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

13
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

14
Check-up Surface Area

• Handout of examples
• Lesson Practice Surface Area

15
Cubic Units

• Volume how much three-dimensional (3-D) space a
  solid occupies
• Why do we call it Cubic?

?
16
Volume Formulas

• PSSA Formula sheet
• Prism, Cone, Pyramid, cylinder (many types),
  sphere

17
Check-up - Volume

• Handout of examples
• Lesson Practice - Volume

18
More Practice if you need it

• Measuring Around
• What happened when Orgo tore up a PUZZLE Book?
• Surface Area of Rectangular Prisms
• Comparing Volumes

19
Ticket out the Door

• Post-Test same as Pre-test???
