Paths to follow with a crayon, from one picture to another, for children not ready for letters yet. The roads get narrower and the lines get trickier as the ages go up.
Straight lines inside a wide road. Staying in the road is the goal; landing on the dashes is a bonus.
Curves that go up and over without stopping, on a narrower road.
Peaks, corners and loops, the strokes letters are made of. No road now, just the line.
One shape at a time: follow the wide road all the way around, trace three dotted copies, then find and color every matching shape at the bottom.
