Abstract
Abstract A golf putting teaching aid for helping a golfer learn proper accelerated putting includes a rectangular putting surface having a putter path line located lengthwise down the center of the putting surface to indicate the proper path of a putter during the putting stroke. A plurality of squaring lines are disposed perpendicular to the putter path at different distances from the cup. These squaring lines serve as a visual aid for the golfer to indicate the proper orientation of the putter head when it strikes the ball, i.e., perpendicular to the path of the golf ball. A stroke length ruler is locatable along an edge of the putting surface and has indicia for aligning the stroke length ruler with the position of the golf ball and for indicating the proper backswing and follow-through in relation to the distance of each putt.
