These are printable OG phonogram cards. Included are 75 of the basic English phonograms (letters and letter combinations) with pronunciation, key words, and associated spelling rules on the back. There are 20 pages in this PDF file which alternate (front, back, front, back) so they are easily printed in duplex mode. These drill cards are similar to those accompanying Logic of English, All About Spelling, and All About Reading. These cards are great for promoting phonological awareness.
