Where are the double-letter flashcards?

We have flashcards for zz, ll, ss and ff but other common double-letter graphemes (tt, pp, nn, mm, dd, gg, rr, bb) are taught within words.

The graphemes cc (e.g. soccer and hiccup) and vv (e.g revved) are rare but are included on the Grapheme chart so that children have an awareness of all the possible double letter graphemes.
