Exploring Quadrilaterals Activity Standards/Benchmarks Alignment and Math Forum Resources

Alignment to Radnor Township School District Mathematics Standards and Benchmarks:

Standard 2: Geometry and Measurement Concepts

Apply the properties of one-, two-, and three-dimensional geometric figures to describe, reason, and solve problems about shape, size, position, and motion of objects. Identify attributes, units, and systems of measurements and apply a variety of techniques, formulas, tools, and technology for determining measurements.

Benchmarks

is familiar with assorted two-dimensional objects (7)
