A Word Reservoir
Have you ever tried to teach the word ‘said’?
A word reservoir is what I like call the groups of word that are listed, not according to dictionary order, but phonogram or phoneme order. The lists are comprehensive, so that the phonograms can be taught or reviewed at any grade level and complexity. My experience is that the lower grades put a great deal of effort into teaching the various sounds in the English language but as a child goes up the grade levels they are taught less and less and children forget them.
