Looking for Answers about Back Home Industries 70 Basic Phonogram Cards?

The English language is made up of 45 sounds which we spell in approximately 70 ways. A phonogram is a letter or set of letters used to represent one or more of these 45 sounds. The quickest, most natural way to learn to spell and to read the English language is to begin by learning the 70 foundational phonograms. The packet contains cards for each of these. The front of the card contains the phonogram in isolation. The back of each card gives the teacher all the information she needs to teach the phonogram. These cards should be used in conjunction with "Teaching Reading at Home" (stock #244017).
