develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more complex shapes

Area	Lesson: Comparing shapes with the same areas but different perimeters.
Length, Perimeter, and Area	Lesson: Introduces students to length, perimeter and area.
Tessellate!	Activity: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.
Area Explorer	Activity: Learn the difference between perimeter and area. A shape will be automatically generated with the perimeter that you choose. Calculate the area of this shape. Area Explorer is one of the Interactivate assessment explorers.
Shape Builder	Activity: This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter. Shape Builder is one of the Interactivate assessment explorers.
Shape Explorer	Activity: Learn the difference between perimeter and area. A random shape will be automatically generated. Calculate the area and perimeter of this shape. Shape Explorer is one of the Interactivate assessment explorers.

develop strategies to determine the surface area and volume of selected prisms, pyramids, and cylinders

Surface Area and Volume	Lesson: Introduces students to the concepts of surface area and volume.
Surface Area and Volume	Activity: Manipulate dimensions of a triangular or rectangular prism, and investigate how the surface area and volume change. Parameters: length, width and height.

select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision

Area	Lesson: Comparing shapes with the same areas but different perimeters.
Pythagorean Theorem	Lesson: Students learn how the Pythagorean Theorem works and how to apply it.
Perimeter	Lesson: Introduces students to the concept of perimeter.
Length, Perimeter, and Area	Lesson: Introduces students to length, perimeter and area.
Clock Arithmetic	Activity: Work with various types of clocks in order to learn about modular arithmetic operations. Parameters: Number of hours on the clock.
Tessellate!	Activity: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.

solve simple problems involving rates and derived measurements for such attributes as velocity and density

Reading Graphs	Lesson: Demonstrates the connections between formulas, graphs and words.
Limits	Activity: This is the limits activity

use common benchmarks to select appropriate methods for estimating measurements

Estimation	Lesson: Introduces students to making estimations.
Estimation	Lesson: Introduces students to making estimations.
Spinner	Activity: Create a game spinner with one to twelve sectors to look at experimental and theoretical probabilities. Parameters: Number of sectors, number of trials.
Comparison Estimator	Activity: Compare two sets of objects, using estimation to determine which is greater. Estimate a number of objects, the length of a line, or the area of a shape. Parameter: error tolerance. Comparison Estimator is one of the Interactivate assessment explorers.
More or Less Estimator	Activity: Practice estimation skills by determining whether the number of objects, the length of a line, or the area of a shape is more or less than the number given. Parameters: error tolerance. More or Less Estimator is one of the Interactivate assessment explorers.
