NUMBER PLAYBOOK 03
How to Read a Number Grid
Use systematic scanning, row totals, intersections and visual anchors without guessing.

Use systematic scanning, row totals, intersections and visual anchors without guessing.
The essential idea
Begin at the top left and scan in one direction. Random jumping makes duplicates and missing values harder to notice.
A practical method
Mark visual anchors such as repeated digits, centre cells and strong colour contrast. Then compare only the cells relevant to the current task.
Use the skill responsibly
A structured scan improves speed because it reduces repeated work, not because it predicts random outcomes.
Patterns are useful for learning; random outcomes remain random.
