The Grammar Flash Cards used to be listed as a required supplement for Foundations D and included in the Foundations C-D Set, along with the Advanced Phonogram Flash Cards. However, only eight of the Grammar Flash Cards and eight of the Advanced Phonograms are introduced in the D lessons, and these skills are not a primary emphasis in the curriculum, as the focus in Foundations is on teaching reading.
Since these items were only occasionally used, we did not feel that the role they played in the lessons merited the additional cost they added to the set (about $30). Foundations D now lists these items as optional, and a free PDF download of the cards from these sets used in D lessons is now available on our website: Grammar Flash Cards used in D.
There are grammar concepts taught throughout Foundations, especially in Foundations D; however, these lessons are meant to be a beginning introduction to English grammar for the purposes of learning how to read.
The Logic of English Essentials curriculum, on the other hand, uses the Grammar Flash Cards frequently, so they are included in the Essentials 1-7 Set and the Essentials 1-7 After Foundations Set.
