Investigate how changes in the base and height of a trapezoid affect its area.

This activity is adapted from one of the TI books. Students measure lengths and widths of rectangles and record for the class to see. Each group's rectangle has the same perimeter, but different areas. After a discussion, students make...

Label the given measurements in a diagram. Find the side length of a square when given the area. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A lesson focusing on the area of polygons and the circumference of circles. Engaging, interactive practice worksheet, lesson plan, and related classroom activity complete this lesson.

This tasks gives a verbal description for computing the perimeter of a rectangle and asks the students to find an expression for this perimeter. They then have to use the expression to evaluate the perimeter for specific values of the...

The purpose of this task is to ask students to write expressions and to consider what it means for two expressions to be equivalent. Aligns with 6.EE.A.

Students will play learning games to explore area, measurement, and angles.

This site contains an extensive list of various units of measurement known internationally and across several disciplines. Unit symbols are also included.

In this lesson plan, 7th graders use the formula for circles to determine the area and perimeter.

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

In this Cyberchase video segment, the CyberSquad learns what happens to the area of a rectangle when the shape enclosed by the perimeter changes.
