ETA: Updated verson has extra 8 advanced pages!
There are many curricula that teach the formation of letters based on a clock face. Some teach manuscript, others teach cursive, but both use the sound of dictation to direct the pencil of the pupil to write a letter.
Some use Spell to Write and Read, Logic of English, Salding Method, Clock climbing letters, etc. These are worksheets that have the middle dotted line, they have a red baseline, and blue top guide, and a full face clock throughout the whole page for students to practice their letter formation, then later on their phonograms, and even small words.
