Young scholars compare, resize, and check various shapes by size using a comparison mat from the MathKeys program. Working in pairs, they place three similar shapes on the screen and state which is the largest and smallest in area. They...

Fourth graders investigate the concepts of area and perimeter, and they practice finding the values in various types of situations. They construct different representations of shapes using the area measurements and also explain the...

Fifth graders practice the skills of finding the perimeter and area of different objects. They integrate technology tools by using a computer software program during the class as the second half of an assessment of measuring student...

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.

Students use formulas for common geometric shapes in order to solve a real-life, multi-step problem. They calculate material cost based on price/sq. unit.

Eighth graders discover how the change in the dimensions of a shape cause a change in the overall area of the shape, but the perimeter stay the same. They, in groups, go out to the playground and construct large areas using stakes and rope.

Students calculate the perimeter of a random shape on a grid.
