### Lesson Objective

Students will analyze properties of solid geometric figures in order to calculate their volume.

### Lesson Plan

Engagement (Warm- Up) 5 min.:
Review the formula for Area and the Homework.

Exploration (Notes) 10 min.:
Teachers should discuss with the students that soild lfigures are three dimensional and those dimensions consist of Length, Width, and Height.

Teacher can ask the students to find the relationship between Area and Volume
- How are the Alike? Different?

Volume is the amount of space an object takes up. It is measured in cubic units. (exponent 3)

Formula for Volume of square/ rectangular prisms
V= L x W x H

Formula for Volume of Triangular prism
V= 1/2 (b)(h)L

Formula for Volume of square/ rectangular pyramids
V= 1/3 ( L x W x H)

Explanation (Instructional) 20 min.:
Teacher will display a cube that has a length of 2in., width of 2 in., and height 2.in.
V= 2in. X 2in. X 2 in.
V= 8in. cubed

Teacher will display a square prsim that has a length of 5 ft. and a width of 10 feet and height of 2 ft.

Teacher can ask the students about the formula for prisms and why the measurement differs from cubes. Based on the formula, what should we do to find the volume of this square prism?

V= 5ft. x10ft. x 2ft.
v= 100 ft. cubed

Now students must break into groups and try to find the Volume of the figures that they created in their groups.
-Square Prism
-Square Pyramid
-Triangular Prism
-Triangular Pyramid

Teacher will allow each group10 minutes to work together to find the dimensions and calculate the volume.

Once the time is up, each group will present their findings on a different solid.
Teacher will give confirmation of correct answers.

Elaboration (Independent) 15 min.:

Homework: Volume WKST

Evaluation (Closing) 5 min.:
Exit ticket:
What is the volume if a square pyramid has a length of 10cm and a height of 11 cm?
