Standard: Use Math to Solve Problems and Communicate

Component of Performance How activity addresses component Understand, interpret, and work with pictures, numbers, and symbolic information. Students use numbers to calculate perimeter, area and volume of shapes using formulas. Students construct tables with data. Apply knowledge of mathematical concepts and procedures to figure out how to answer a question, solve a problem, make a prediction, or carry out a task that has a mathematical dimension Students will perform mathematical operations and use calculators. Define and select data to be used in solving the problem Students will decide which values should be substituted into the formula Determine the degree of precision required by the situation Students will estimate the change in the area of the figures. Students will round numbers when working with circle problems. Solve problem using appropriate quantitative procedures and verify the results are reasonable Students will use drawings, models and mathematical formulas to confirm results. Communicate results using a variety of mathematical representations, including graphs, charts, tables, and algebraic models Results will be communicated in words, illustrations, and mathematical formulas.

Purposeful, Transparent, Building Expertise

Purposeful and Transparent Lesson provides lots of practice using formulas for perimeter, area and volume. Students use various models and diagrams to investigate the formulas. Contextual Student ideas are encouraged as they apply this lesson to real-life situations such as quilting, tiles, etc. Building Expertise Students reinforce a basic knowledge of geometric formulas and expand that knowledge to look at basic number principles.
