How to read this map
Each chip is one standard, placed in its grade. A line between two standards means the earlier one was verified as a prerequisite for the later one, against the official framework documents and published curriculum progressions. If a student is stuck on a standard, look one column left. If they have mastered it, the lines to the right show where that skill goes next. Every chip links to a full breakdown of the standard with teaching ideas. How these connections are verified.
