Every text in The Essentials Reader is carefully controlled for which phonics and spelling concepts are used, in order to provide reading practice that students can complete successfully using skills they have been taught. New spelling concepts are added in each chapter.
For those using the current version of our Essentials program, The Essentials Reader unit numbers correspond exactly with the Essentials unit numbers. Students who have completed the corresponding Essentials unit have been introduced to all the tools they need to decode every word in that unit of The Essentials Reader.
For those using another program, a table in the appendix of The Essentials Reader lists the new phonograms and spelling rules needed for each unit. Those using the 1st edition of our Essentials program or any other Orton-Gillingham-based or other systematic phonics program can use this table to determine when to use each text.
