Standards

• 7.1.spi.8. Solve one and two step real world problems involving whole numbers, fractions, and decimals.

• 7.3.spi.2. Classify triangles by angle, size, and length of size.

• 7.4.spi.6. Estimate length, perimeter, circumference, area, and volume using a variety of strategies.

• 7.4.tpi.3. Use a variety of strategies to estimate length, perimeter, circumference, area, and volume.

Diameter and Circumfrence

• You will begin at the front doors of Bartoo Hall. You will find the center circle in the design of the door.

• First find the Diameter of the circle.

• Then find the Circumfrence.

Measurement and Perimeter

• Walk down the steps and turn right. Walk to memorial gymnasium then turn left and walk across the street. Walk on the sidewalk until you to the flower octagon.

• Measure the length of one side, of the flower octagon.

• Use this measurement to find the Perimeter.

Fractions• Turn left and walk across

the grass to the sidewalk parallel to the one you are on.

• Find the octagon with the triangles.

• Stand on one of the triangles.

• What fraction of the octagon are you standing on?

• What fraction of the octagon are you NOT standing on?

Determining Angles

• Then you turn completely around and face Bartoo Hall. Walk across the street to the trashcan in front of Bartoo Hall.

• Find the measurements of all three angles of the triangle.

• Then determine the type of triangles they are.
