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.
Solutions
• Slide two -Diameter and Circumfrence: 7 3/4 in. and approx. 24.35
• Slide three - Measurement and Perimeter: 9ft and 72ft.
• Slide four - Fractions: 1/8; 7/8• Slide 5 - Angles :50, 50, 80; acute
isosceles triangle.
