- In Think and prove, make your choice, then press Prove it. Follow one short task at a time: simplify, make equal-sized parts, or explain the size of the parts. Enter just the new numerator when asked. Check step, read your working, then Continue.
- Hint helps you start. Show me works out the current step. Show bars explains the shaded parts. After proving, compare again; you can change your first choice. Your summary counts proved rounds with and without help.
- The player whose card is greater wins both cards and the middle pile. Tied cards stay in the middle. After eight rounds, any final tied pile is shared equally. Most cards wins. Card scores depend on the cards dealt; they are separate from your proofs.
- Show strategy explains your comparison after checking. The bars always use the same-sized whole; their labels match the parts shown.
- New game keeps your settings and deals a fresh arrangement. Restart this deal replays the current arrangement with progress cleared. Changing a setting begins a fresh game.
- Share this setup includes only your mode, card choice and player count. A shared link opens a fresh unsolved game. Print prints the current display on one A4 landscape page; face-down cards stay hidden.
- Use Tab to move between controls and Enter or Space to activate them. There is no timer.
- Opened from a curriculum step? The label above the choices shows your step. New game keeps the cards matched to that learning.
