Week Four
NOTES- any slide with a green title should be written down in your notebook.
Lesson #7- Measurement and Geometry
2.1
Perimeter, Area, Volume(10 mins)
• Perimeter- the distance around the object.
• Area- the inside of a 2-D shape.
• Volume- if you filled a 3-D shape.
• Surface Area- the covering of a 3-D shape.

10 feet
Perimeter = side + side + side + side = 10.5 ft + 18 ft + 10.5 ft + 18 ft = 57 feet
