Perimeter, Area and Volume Re-Teach

Monday - May 15 AM Meeting

Meeting Agenda

• Weekend Update

• Re-teach

Weekend Update

• Tell us what you did on your weekend

Perimeter

• Forget about the formulas, we're going to focus on the basics!

• Perimeter is the distance around an object.

• It's like building a fence. If you want to build a fence you need to know how long each side needs to be.

• To know the total distance around a shape you must ADD up all the sides.

Perimeter

• Add all the sides together

• To show your work you must show you adding the sides together

• P = 4 + 6 + 5

• P = 15 cm

• Your answer on a test should look like this

Area

• Area is the space inside of a 2-D (flat) shape

• Rember the garden? Area is measuring how big the garden itself is, not the area around it.

• All you need to remember is the formula A = L x W

• L means Length it is the long side of the rectangle

• W means width it is the short side of the rectangle

Area

• To find the area of a rectangle all you need to do is remember the formula A = L x W.

• A = L x W

• = 10 x 3

• = 30 $ft^2$  

• Your answer on a test should look like above

Volume

• Volume is the amount of space inside a 3D shape

• To find the volume of a rectangular prism you need to remember the formula V = L x W x H

• L means the length

• W means the widgth

• H means the height

Volume

• To find the volume all you need to remember is V = L x W x H

• V = L x W x H

• = 4 x 2 x 1

• = 8  $mm^3$  

• This is exactly what your answer should look like. Write the formula. Show your work. include measurement and cubed.
