Free worksheets for area of triangles, quadrilaterals, and other polygons

OK, maybe this is not the best time of year to mention this (I realize your minds may be on other things :), but if I don't do it now, I may forget it later : (

I have made a new worksheet generator... for areas of triangles, parallelograms, trapezoids, generic quadrilaterals, pentagons, and/or hexagons (you can choose the shape(s) to be used).

It uses the coordinate grid. You can select either the first quadrant or all quadrants.

Something like this:


The answer key shows the polygon drawn in the coordinate grid, and of course the area in square units.

This is a focus topic typically for 6th grade math, but may also appear in 5th and 7th grades.
