DR241 pairs Double-Jump 2x2 Symmetry (BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4) with Visual Modality (Spatial Matrix Inspection): learners verify Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2), master Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell, and eliminate thinking row 2 of a 2x2 pattern turns blue before the column switches.
DR241 drill board (BBPPBBBPPBPPPBBPPPBBBP): 10 Big Road columns, 19 Big Eye Boy, 17 Small Road, and 14 Cockroach Pig marks.
Column 3 has 3 beads. Column 2 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 2.
This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.
Column 5 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 2.
BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4
Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell
Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2)
Thinking Row 2 of a 2x2 pattern turns blue before the column switches
Trace both Row 1 (Rule 1) and Row 2 (Rule 2 Case 2a) in a 2x2 shoe by sight-tracing column heights and reference cells across the 6-row grid
Under Visual Grid Trace (DR241), Double-Jump 2x2 Symmetry isolates BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4 and Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2), turning BBPPBBBPP-BPPPBBPPP into a hands-on 19-mark verification.
Applying Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell in DR241, Column 3 has 3 beads. Column 2 has 2 beads. Different depth → blue (≠). Those 17 Small Road dots and 14 Cockroach Pig slashes accompany BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4 during sight-tracing column heights and reference cells across the 6-row grid.
