[Free Registration/Login Required] In this lesson, students will connect the concepts of counting each square unit and multiplying the side lengths to compute the area of a rectangle. They will extend this knowledge by computing a side...

Practice finding the area of rectangles by counting unit square. Create rectangles with a given area by covering unit squares. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video...

Sixth graders find the area of rectangles, triangles, parallelograms, and trapezoids by using formulas or by composing into rectangles or triangles.

This applet will show you how to divide the parallelogram into pieces, arrange them together to form a rectangle, and then use the formula for the area of a rectangle to find the area of the parallelogram.

Count unit squares and partial unit squares to find the area of shapes.

Sixth graders use the area formula for rectangles to solve real world and mathematical problems.

In this instructional activity, students will be required to generate a formula for volume of a rectangular prism. Students working in cooperative groups will use prior knowledge for finding area of a rectangle to determine the "amount...
