Cylinder DAY 1

Cylinder: Warm-Up TIME: 5 minutes DIRECTIONS: Work at your table (in groups of 3 to 4) Define in your own word to what Cylinder means. What are the characteristics of the word? What does it look like? Use descriptive language to describe the word. Provide examples that related to the idea Provide non-examples or opposites/ antonyms

Warm-Up: Cylinder Facts Characteristics: It has a flat base and a flat top The base is the same as the top, and also in between It has one curved side Because it has a curved surface it is NOT a polyhedron/prism

Where do you see cylinder in your everyday life?

Cylinder: Formula 2-D dimension 3-D dimension FILL IT UP Height/ Altitude/layer

Problem 1 Find the volume of the cylinder with a diameter of 12 inches and a height of 8 inches. R= D/2 =12/2= 6 inches V= pi* r^2 * h V= (3.14) (6 inches^2) (8 inches) = cubic inches or inches^3

Problem 2 Students: Work in groups of 3 to 4 students Materials: two rulers and two candles Work at your table: You have two cylindrical candles with different dimensions on your table. How can you determine which candle took more wax to make? Which one took more max to make? Use your mathematics reasoning to explain your reason. Think: What is the question ask you to find? In order to answer the question, what do we need to find first? Be ready to share with the class

Exit Slip On your note card write down: NAMETOPIC: Volume of a Cylinder DATE PERIOD You don’t have to write down the question Draw out the picture and label everything correctly SHOW YOUR WORK and BOX YOUR ANSWER Question: Find the volume of a cylindrical fish tank with a diameter of 4 feet and a height of 3 feet.

Life Application DAY 2

Warm-Up- Math Flip book! TIME: 10 minutes DIRECTIONS: each student has 2 pieces of white papers Volume By: __________ Cylinder Cone Sphere Cylinder Draw a picture of a cylinder Include the formula Provide an example: COPY THIS DOWN AND SOLVE IT “Find the volume of a cylinder with a diameter of 6 and a height of 2.”

Popcorn Cylinders Anyone? Students: Work with your assigned partner Materials: Bag of popcorn, two papers, and rulers Work at your table: With your assigned partner, work together on the Popcorn Cylinder Activity. Follow the instruction on the worksheet.

Cone DAY 3

Warm-Up 1)What are some of the characteristics of a cylinder? 2)Find the volume of a cylinder with the diameter of 20 centimeters and a height of 10 centimeters? 3)The tank contains a total of 100 cubic inches of water. The tank has a radius of 25 inches. What is the height of the tank?

Where do you see cylinder in your everyday life?

Cone: Formula IN ORDER TO SHOW THAT THE FORMULA WORKS: The cone and the cylinder have same height and have the same Based area.

Cone: Formula As a table, discuss how many how many cones do we need to fill up this tank?

Cone: Formula If you need three cones to fill up a cylinder with the same length and Based area, then it is the same as saying you only need 1/3 of a cylinder to fill up one cone.

Problem 1 Find the volume of the cone with the radius of 2 inches and a height of 10 inches. V= pi* r^2 * h V= (3.14) (2 inches^2) (10 inches) = cubic inches or inches^3

Problem 2 Work at your table: You want to make orange juice. Each orange contains 20 cubic millimeters. You want to put the juice in a cone that has a height of 100 millimeters and a radius of 30 millimeters. How many oranges do I need to fill up the cone completely? Think: What is the question ask you to find? What formula do you need? Be ready to share with the class
