Pick the unit sets you need, tweak the list, print a one-page reference chart.
Each saved chart keeps its own unit sets, lines, order and column count, so a “Grade 5 metric only” chart and a full reference can sit side by side. One chart is always kept.
One click checks the right sets for the grade band — elementary gets the within-system basics plus time; middle school adds cross-system conversions and temperature formulas. Fine-tune with the checkboxes after.
Fewer unit sets read better in 1–2 columns; a full chart with several sets fits more on one page in 3.
Use the up and down buttons to put groups, and the lines inside a group, in the order you want printed.
