By grade 4 the goal is fluency: whole sentences and passages on 1/2-inch lines, with spelling lists doing double duty.
Fourth grade is about speed and stamina. The sentence and pangram sheets sit on 1/2-inch rules, close to ordinary notebook paper, and the passage sheet asks for several lines in a row so the writer learns to keep slant and spacing steady from line to line. The spelling list doubles as handwriting practice: words such as because, different and through show up in every piece of writing and are worth having in the hand.
At this stage a child should be writing cursive faster than print. If not, the cause is usually a few letters that still need thought; the letter pages identify them and print targeted sheets. The generator's spelling-list template takes any weekly list and the sentence template any passage from the class reading, so the practice can follow the curriculum instead of standing apart from it. Pangram sheets are the fastest diagnostic here: one line contains every letter, so a teacher can see in seconds which forms have slipped and which joins have opened, and the letter pages print a targeted sheet for each. The passage sheet is also where a child first writes for meaning in cursive rather than for practice, which is the point of the whole progression.
