In Pairs: 1.Estimate the area of each trapezoid 2.Use the matching sticker to make a parallelogram. Find the area of the parallelogram 3.Use what you know about the parallelogram to find the area of the trapezoid

Discussion When you calculated the area of your trapezoid by turning it into a parallelogram, is it the base that doubled? Or the height?

What part of your formula will be different from the formula for a parallelogram, the base or the height?

In Tribes  Discuss How can we calculate the base portion of any trapezoid? Use what you now know to create an equation to represent the area of any trapezoid

MATH CONGRESS

Homework Take home 2 trapezoids from your group and use the area equation established in class, along with measurement calculation rules, to find the area of those 2 trapezoids
