The green Phonograms are similar to Montessori sandpaper letters, these are cursive version letters in sandpaper on green colored cards, each phonogram represent sound . 
Phonogram Cursive Letters comes in a wooden storage box.
The sandpaper Phonograms are 2 letters that come together to produce a unique sound- such as ee in cheek.
These are necessary for English, since every letter does not always make the same sound- and there are certain sounds which we typically represent with a 2 letters phonogram.
