📦 What is the Cardbox?
Think of it as MadMath’s practice memory. Every multiplication fact receives a practice rank from 0 to 3. The rank is not a school grade; it simply tells Smart Practice how often that fact should come back.
Rank 0
Needs practice
Shown most often in Smart Practice.
Rank 1
Learning
Still appears frequently.
Rank 2
Getting stronger
Appears less often as recall improves.
Rank 3
Strong
Shown least often, but still revisited.
How the rank changes: each correct answer moves a fact up one rank. A wrong answer moves it back to Rank 0. Smart Practice then gives lower-ranked facts more chances to reappear.
Resetting removes saved learning data. Use it only when you deliberately want that table to start fresh.
Your Saved Facts
Click a column heading to sort. Accuracy always means correct answers divided by all checked attempts for that fact.
