- 0 Start here A roadmap: fold lines, how many a shape has. And shapes that match partway through a turn. · 3 min You are here
- 1 Fold it, and it matches A line of symmetry is a fold line. It lands a shape exactly on top of itself. · 5 min
- 2 Not every middle line A line can cut a shape into two equal halves. And still not be a line of symmetry. · 6 min
- 3 How many fold lines? A shape can have no fold line, one, several. Or a count that never stops growing. · 5 min
- 4 Symmetry around us Fold lines in capital letters, in leaves. And in patterns people cut and draw. · 5 min
- 5 Matching partway through a turn Some shapes land back on themselves partway through a turn. Even with no fold line at all. · 6 min
- 6 Half a picture decides the rest Given half a figure and a fold line. The missing half is worked out, not guessed. · 5 min
- 7 The big picture Six ideas, tied together. · 4 min
- 8 Track quiz Cheat-sheet table plus a reveal quiz. One question per idea, and one for the trap. · 7 min
