In this geometry learning exercise, 4th graders identify how many square units is the area of each of the shaded shapes. Then they find the areas of the rectangles when the sides are given. Students also draw the figure described for each.

In this volume worksheet, students calculate the volume by finding out how many units each figure has. Students complete 4 problems where they find the volume.

In this trig functions worksheet, students find the trig values of 46 problems.  Students find the trig values of various radian measures.  Students use trig properties to prove trig identities.

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...
