#### Lesson Overview:

This activity gives students an opportunity to explore aerodynamics, geometry and more through the world of kites. Students will learn how a kite flies, how to choose and estimate how much material is needed for a kite, and how to put kites together. For the group activity, students can choose a kite to build and come back to the Kite Builder's Club to share their ideas and results with other PlaneMath users.

#### NCTM Process Standards Covered in Go Fly a Kite:

• Standard 1: Mathematics as Problem-Solving
• Standard 2: Mathematics as Communication
• Standard 3: Mathematics as Reasoning
• Standard 4: Mathematical Connections

#### NCTM Content Standards Covered in Go Fly a Kite:

• Standard 5: Estimation
• Standard 8: Whole Number Computation
• Standard 9: Geometry and Spatial Sense
• Standard 10: Measurement
• Standard 13: Patterns and Relationships

#### Aeronautics Content:

• Parts of a kite
• How kites fly
• Building and flying kites: how materials, construction, and weather conditions affect kite performance

#### Objectives:

• Students will restate how a kite flies.
• Students will identify the parts of a kite and how it helps make the kite fly.
• Students will compare geometric shapes to match parts of a kite to a whole kite.
• Students will cut, measure, and arrange the pieces of a kite that will fly.
• Students will estimate the amount of material to use when building a kite.

#### Prerequisite Skills:

Estimation strategies, spatial sense, problem solving skills

#### Vocabulary:

• Frame - sticks or poles which keep the kite stiff so it doesn't collapse in the wind. The spine is the backbone of the kite, while struts or spars are side or cross sticks which keep the kite open.
• Kite covering - the material (usually fabric, paper or plastic) used to catch the wind; also called the kite face or sail.
• Tail - streamers or bows added to the kite to keep it stable and oriented to the wind.
• Line - the string which holds the kite in the wind; the string which keeps you connected to your kite.
• Bridle - connects the kite to the flying line so that the kite is positioned at a proper angle to the wind.
• Kite - a tethered object that relies on wind for lift.

An appropriate time to discuss vocabulary may be after the lesson when students have experienced the activities.

#### Materials:

Pencil, paper, calculator, MathPad (distributed by IntelliTools).

Downloadable files may be printed, enlarged on a copier, if needed, and glued to cardboard and cut out for easier manipulation. For students with physical handicaps, consider glueing magnets to the back of each piece and letting the student move the magnetic pieces on a cookie tray.

Materials needed for building kites are included in each set of kite building plans. Additional easy kites to build are included in the books referenced below.

#### Class Organization Guidelines:

Collaborative groups help with classroom and student management and assist student learning. Optimally, in computer lab settings 2-4 students at one computer support each other and learn effectively. Groups of students can be organized with four students to a computer with each student taking a role: Reader, Navigator, Reporter, Captain.

For example, the Reader reads what is on the screen to the group. The Navigator maneuvers the mouse. The Reporter reports back to class. The Captain keeps track of time and monitors group interaction. Three-student and two-student groups can be assigned a combination of these roles. For instance, Reader and Navigator roles can be assigned to one student while the other student can be the Reporter and Captain.

#### Teacher Tips:

PlaneMath provides a means to accommodate students with physical and learning disabilities as well as to enhance math learning for all students. Thoughtful planning and management strategies are effective methods to accomplish these goals. Grouping, functional roles, access to well-designed lessons, learning styles along with student interactions are considerations for management of students. For more information for students with disabilities, contact the Alliance for Technology Access. For additional information go to the main Teacher's Page for PlaneMath.

We encourage teachers to send us examples of additional problems or activities that they have found useful; we will then post these on this page. E-mail us with your suggestions at planemath@infouse.com.
