8 cards with the formulas, rules and traps from this lesson. Answer in your head, then flip to check.
Rule · 1/8
Grid assembly: how many filled cells should the finished drawing have?
Exactly the sum of the pieces' cell counts (7 + 5 = 12). Fewer cells means an overlap or lost material; more means invented material.
Term · 2/8
Edge contact vs. corner contact
Edge contact: pieces share a full side of at least one cell. Corner contact: they touch at a single point, like diagonal checkerboard squares. A required marked-edge join needs flush edge contact.
Rule · 3/8
How often must each supplied piece appear in a correct assembly?
Exactly once, with its shape unchanged. A missing piece leaves the whole incomplete; a duplicate adds material that was never supplied, even if the outline looks tidy.
Common trap · 4/8
If an answer's outer outline (silhouette) matches, is it correct?
Not necessarily. Different arrangements can share one outline while seams and connector marks sit in different places. After the outline passes, check seams and marks.
Rule · 5/8
Boundary-dot convention: when do two marks form a side-by-side joint?
A right-side dot pairs with a left-side dot in the cell directly to its right: same row, columns differ by exactly 1. Top-to-bottom joints share a column with rows 1 apart.
Common trap · 6/8
Why is a one-cell shift of a correctly shaped piece so dangerous?
It barely changes the picture but moves the mark a full cell: a horizontal shift leaves a gap, a vertical shift puts the marks on different rows. Almost correct is wrong.
Strategy · 7/8
How can tracing a piece's edge expose a flipped piece?
List features clockwise around the edge (long arm, notch, short arm). A turn keeps that cyclic order and only changes the starting point; a mirror image reverses it.
Strategy · 8/8
Fast-to-slow triage order for wrong assembly choices
First check piece count and total cells, then that each piece keeps its shape with no flip, then that every pair of marks touches exactly. A correct cell count alone never proves orientation.
