This tool is designed to build an understanding of same and different by using pictures to focus and train the ear to hear the beginning letter sound of an object. When naming the object on the card exaggerate the first sound (/b//b/ /b/ bear) (/g/ /g/ /g/ ghost) to differentiate from the other sounds within the word, then ask do these sound the same or different? This pre-reading skills helps to develop foundational skills needed prior to learning letter sounds and blending words. This set comes with 2 cards per consonant letter. It would be great to use as flash cards, memory match, and go fish.
