Applet contains a modifiable parallelogram that students can transform into another familiar figure (rectangle.) Since the area of the rectangle is the same as the area of the original parallelogram, students can then more readily see that the formula for the area of any parallelogram is Area of a Parallelogram = (Base Area)(True Height).

Area Formulas: In this 4-lesson unit, students use the area formula for a rectangle to discover the area formulas for triangles, parallelograms, and trapezoids. Students also consider irregular figures whose areas can be determined by estimation or decomposition.

Please try this FREE set as an introduction to my wide variety of printable Multi-Match game cards. With these cards, students match triangles shown on grids to the area, to calculation cards, or to another triangle with the same area (CCSS 6.G.1). This set is also available as part of a Grade 6 Games Bundle recently featured in th TpT newsletter. ~by Angie Seltzer
