Students flip the shading across it, count the squares, write the answer, match it to a suspect, and cross suspects off until one is left standing. The fold moves as the cases go on, which is what makes it harder than it looks.\u003c\/p\u003e\n\n\u003ch3\u003eQuick Details\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSkill:\u003c\/strong\u003e Lines of symmetry and completing a symmetrical figure · \u003cstrong\u003eGrades:\u003c\/strong\u003e 3–4 · \u003cstrong\u003eFormat:\u003c\/strong\u003e 5 mysteries in difficulty order + full answer keys (printable PDF) · \u003cstrong\u003eTheme:\u003c\/strong\u003e Around the school\u003c\/p\u003e\n\n\u003ch3\u003eThe 5 Mysteries\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThe Mirror Mural\u003c\/strong\u003e — Half of every mural has been washed off; flip the shaded squares across the fold and count them all.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Missing Halves\u003c\/strong\u003e — Somebody stopped halfway through copying each bookmark, so students count the shaded squares with no matching partner.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Flipped Lab Tray\u003c\/strong\u003e — The fold now runs across the grid rather than down it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Backwards Banner\u003c\/strong\u003e — The shading sits on the right of the fold, so it flips left instead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Canteen Cut-Outs\u003c\/strong\u003e — The cut-outs are folded every which way, so students have to find the fold first.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Teachers Love It\u003c\/h3\u003e\n\u003cp\u003eZero prep — print and teach.
