This is a SmartBoard file that introduces 8 plane figures: square, rectangle, trapezoid, parallelogram, triangle, pentagon, hexagon, and octagon. Each slide lists the attributes of the shape; the attributes are covered by a rectangle, so you can reveal them one by one. All the shapes are located at the bottom of the slide, so as you reveal attributes, you can discuss each shape to determine which one is correct. After all attributes have been revealed, drag the correct shape into the answer box.
In addition, the definition of a plane figure and the terms vertex/vertices, parallel lines, and right angles are introduced and illustrated. With the introduction to these terms is a small activity to identify illustrations of the terms.
I can't upload thumbnails of my SmartBoard files, so please download the preview to see what the file is like.
