This set covers the 26 lower-case letters, one per row, across 3 sheets. Letters are about 0.46 of an inch tall measured to the top writing line. Close to ruled paper. At this size the sheet is practice rather than instruction, and fits six repetitions to a line.
The letters to trace are broken outlines, so the hand carries the stroke between marks rather than following a solid shape.
Each row has a solid top line, a dashed middle line at the x-height and a solid baseline. The middle line is what makes letter proportion teachable: a letter that overshoots it is wrong in a way a child can see without being told.
Letterforms are Andika, a typeface designed for literacy teaching with the single-storey a and g that primary instruction uses — not the double-storey forms found in most text faces.
