agenda

• 1). Present Homework in groups• 2).group work with volume• 3). Lesson 25• 4) comprehension check• 5) exit ticket

In groups

• Take 10 mins. Make sure you agree on the solution. Discuss who will present which part of the problem.

• #4 you are broken up into two groups. Each group figure one shape. Then get together and discuss how to combine them.

Will the volume or the surface area of a 3-D

change when the shape is separated into

sections?

Same groups

• You will be given a rectangular prism• The prism maybe whole, or cut into pieces, the steps will be the same

• Fill the box or boxes with the corn pops. You can count them as you add them or you count them after you fill up the box/boxes.

Whole box Two triangles Two rectangles

Three rectangles

Rectangles and triangle

Measured area

Surface area

Now using equations and calculation find volume• Formulas for volumes of solid shapes come from the same concept• (The area of the base)(height of shape)

• Base X height

• This works if base is circle (πr2) rectangle(bh) and triangle(1/2bh)

If you have more than one shape, find the volume of one and then add.

Which changed?

• How will cutting a hole effect the surface area
