What is important or significant about same or different? The eye-brain connection is able to perceive a word (all those humps, squiggles, and ups and downs that mean different things), analyze it, and see it as a word. Same or different exercises train the child in scanning, for example, seeing the like or different attributes of two bunnies or birds, or being able to see the idea of difference in ball-ball-pan. That scanning can later be applied to books, seeing the differences between letters or words. This is also important for understanding and using transitional or joining words such as the, or, and and, which are neither object words nor positional words and must be learned by shape and/or sound. Since every word is different, you are training the child to visually trace those differences. Or, with same, you are also teaching visually tracing the picture to see same or nearly the same, important later on in teaching rhyming words or word families.
Similarly, in what's missing exercises, the child must decide if the cowboy's chaps are incomplete, or the cat lost his tail. Those neural pathways in your child's eyes, are scanning and looking for what's missing, an ability important later in seeing differences between Ms and Ws, or Ds and Qs. Many School Zone products feature activities designed to sharpen these skills. Our Same or Different Workbook and Same or Different Deluxe Edition Workbook are just two.
