A 3-D organizer which can be used for paragraph construction, main idea studies, writing outlines, etc.
Write the main idea (a sentence using the topic) in the middle. Then use the outer "legs" for details to support the main idea.
When cut out around outside edges only and folded at the creases, you have a "stool" which only stands if supported by ALL legs. Our claims and main ideas also only stand in communication if supported by facts, details, and reasons.
