Practice and check
Worked example
Pair cells at the same distance from the mirror line. Copy black to black and leave the matching white cells empty.
Model left · shade right · Black cells: 4 → 8
- Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
- Shade directly in the same grid. The labeled model half or quarter is already complete; do not change it.
- First copy left to right, then top to bottom. Finally use both lines to complete the three empty quarters.
