Math Worksheets and Study Guides Third Grade. Perimeter

The resources above cover the following skills:

Geometry (NCTM)
Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships.
Identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes.
Use visualization, spatial reasoning, and geometric modeling to solve problems.
Use geometric models to solve problems in other areas of mathematics, such as number and measurement.
Connections to the Grade 3 Focal Points (NCTM)
Measurement: Students in grade 3 strengthen their understanding of fractions as they confront problems in linear measurement that call for more precision than the whole unit allowed them in their work in grade 2. They develop their facility in measuring with fractional parts of linear units. Students develop measurement concepts and skills through experiences in analyzing attributes and properties of two-dimensional objects. They form an understanding of perimeter as a measurable attribute and select appropriate units, strategies, and tools to solve problems involving perimeter.
