School:

Solon High School

Ohio Graduation Competencies:

Number and Numeracy

·        Estimate and compute with real numbers.

·        Compute with whole numbers, fractions, and decimals.

·        Apply rates, ratios, proportions, and percents.

Geometry and Measurement

  • Use measurement techniques including scale drawings, formulas, and geometric relationships to find length, perimeter, area, surface area, and volume. Incorporates ninth-grade outcome #10: Find the perimeters (circumference) and areas of polygons (circles).

Mathematical Processes

  • Communicate mathematical ideas, reasoning, and solutions through the use of appropriate mathematical terminology, notations, symbols, definitions, models, and other representations.
  • Apply problem-solving strategies and evaluate processes, strategies, calculations, and solutions to verify reasonableness; and use mathematical reasoning to validate and/or generalize approaches, arguments, strategies, and solutions.

 

Project/Task:
