In this lesson, students will be able to understand and apply geometric principles, including the Pythagorean theorem to solve problems.

An interactive applet and associated web page that demonstrate a right angle (those equal to 90 deg). The applet presents an angle (initially 90 deg) that the user can adjust by dragging the end points of the line segments forming the angle. As it changes it shows the angle measure and a message that indicate which type of angle it is. There a software 'detents' that make it easy capture exact angles such as 90 degrees and 180 degrees The message and angle measures can be turned off to facilitate classroom discussion. The text on the page has links to other pages defining each angle type in depth. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

In this activity, students will use their knowledge of area and perimeter to create a racetrack. Once they have the correct specifications they will guide their car through the track using the properties of magnets.

In the accompanying lesson plan (found in the Support Materials) students will gain an understanding of the Shoshone tribe while learning about the Shoshone Parfleche from the WyomingPBS video.

LEARNING OBJECTIVES:

students will write 3-4 sentences stating/explaining how the Shoshone Parfleche is used.
Students will create an individual parfleche, designed with a line of symmetry, the use of a meter stick for specific measurements and the ability to use creativity to choose their own designs.

Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. While learning how a magnifying glass works, students see how the orientation of an image changes with the distance of the lens from its focal point. They also discover how a prism works by refracting light and making rainbows. And, students investigate the polar nature of light using sunglasses and polarized light film.

Students learn about the history of tangrams.  They will learn about each piece in the tangram puzzle and analyze the shapes to complete geometric puzzles and mathematics problems.

Students will create a route for their ozobot to travel using parallel, perpendicular and intersecting lines. They will also create a "trap" to catch the turkey on the route.

In this video segment from Cyberchase, Digit must a make a straight line between the two points and then follow the path created.

Jackie and Matt are looking at the same object along two different lines, in this video segment from Cyberchase.

In this Cyberchase video segment, Harry tries to snowboard and learns how to measure and identify many common angles.

Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts. One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks. These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format.

--In this activity student will create an amusement park ride out of KNEX that displays a certain type of motion. They will describe their ride. They will then place it in the correct spot on the map by writing the name of it on the worksheet. After all groups have their rides labeled on the map- students should fill in the lines section of the worksheet- identifying parallel, perpendicular and intersecting lines.
