This is a Powerpoint illustrating geometry vocabulary for fourth graders. Visuals and mnemonics aid in memorizing these terms. I recreated a set of flashcards that I had previously listed in Powerpoint so modifications could be made to fit your classroom. Printing the slides as notes (4 to a page) will also provide you with set of flashcards.
Points, lines, line segments, rays, types of lines, types of angles, 2D shapes (triangles to decagons), polygons, parallelograms, quadrilaterals, and more.
