Measurement

Understand measurable attributes of objects and the units, systems, and process of measurement
Apply appropriate techniques, tools, and formulas to determine measurements

Standard

Students engage in problem solving, communicating, reasoning, connecting, and representing as they:

Select, convert (within the same system of measurement), and use appropriate units of measurement or scale. (8.M.1)

Given the formulas, convert from one system of measurement to another. Use technology as appropriate.(8.M.2)

Demonstrate an understanding of the concepts and apply formulas and procedures for determining measures, including those of area and perimeter/circumference of parallelograms, trapezoids, and circles. Given the formulas, determine the surface area and volume of rectangular prisms, cylinders, and spheres. Use technology as appropriate. (8.M.3)

Use ratio and proportion (including scale factors) in the solution of problems, including problems involving similar plane figures and indirect measurement.(8.M.4)

Use models, graphs, and formulas to solve simple problems involving rates, e.g., velocity and density.(8.M.5)

Exploratory Concepts and Skills for Grades 7-8

Measurement

Given the formula, find surface area and volume of pyramids and cones.
Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision
