Going Off Grid

Eric shares a trick to drawing a picture of yourself that's completely to scale-even if it is teeny tiny! It's not magic... it's math! A scale drawing is one that shows a real object with accurate sizes reduced or enlarged by a certain amount,called the scale. By using gridlines, an object can be scaled up (magnified) or scaled down (shrunk) by using corresponding grids to manually produce an image that is the same shape as the original, but is a different size.
