In order to make letter shape recognition an integral part of perception training, the use of the line in its two basic shapes is proposed. Letter shapes may seem exceedingly complex linear shapes to young minds. Thus instead of instruction in configuration, instruction involving transformational activities to manipulate and create the differentiating features of each letter should be given. This perceptual teaching approach may provide sub-skill foundations for learning to read that are important to developing cognitive processes. Learning sequences involving the use of blocks to shape letters provide multisensory, intrinsic, and constructive activities in addition to visual recognition. (MKM)
