Not Yet Gym
Train Bix, a little brain buddy, on real puzzles: a not-yet you come back from with a strategy earns a gold comeback stripe, and the goals you set open new rooms.

Planning a whole lesson? Here is a 45-minute lesson plan that opens the standard and brings the class to this tool.
A 5-minute start
- Open the Gym and tap Bix. Bix hops: that is the Rookie move. Ask: what do you think helps Bix get better at things?
- Tap the Pattern Ladder door and play the first rung together. Then try a harder rung. When a choice says Not yet, the strategy cards slide up. Pick one as a class (for example Break it into parts) and solve it.
- Look at Bix's headband: a gold comeback stripe. Point out the Know-how bar. A first-try solve adds 1, a comeback adds 3, and a comeback after a strategy card adds 4. Ask: why would coming back be worth more?
The three modes
- Gym: five rooms of real puzzles, each a ladder of rungs that get harder. Pattern Ladder (what comes next) and Memory Mirror (watch the pads, then copy them) are open from the start. Light Mat (flip squares until all nine are lit), Number Lift (two buttons, reach the target floor) and Summit Circuit (one hard puzzle from every room) open one at a time, each time a goal is finished. I'm stuck opens the six strategy cards at any time: Try a new way, Slow down and check, Use a hint, Take three breaths, Break it into parts, Ask a friend. Each card really changes the puzzle (a slower replay, labels on the jumps, a glowing next step, a halfway floor).
- Goals: pick one goal card from the board, then make a plan: the strategy you will try first when you get stuck. Your goal and its progress show in the panel. Finishing it opens the next room and asks what helped most.
- Locker: Bix in everything it has earned (sweatband, sneakers, gym bag, star medal), a sticker for every strategy used (a gold star for each one that helped finish a goal), Bix's color, and six Coach's corner cards to flip.
Know-how never goes down, and a mistake never costs anything. Points come only the first time a rung is solved, so each rung pays only once and replaying it is free practice.
Talk about it
- What did you do right after a not-yet? Did it work?
- Which strategy card helped you most today? When else could you use it?
- Was your goal specific enough to know when you had reached it? How could you make it clearer?
- Think of something that is easier for you now than it was last year. What practice helped?
Good to know
- Keys 1 to 3 switch modes. Escape closes the strategy cards. In the puzzles, arrow keys move between targets and Enter or Space taps.
- Save Bix (in the Locker) keeps progress on this computer for a later day. Nothing saves on its own, so a shared classroom laptop starts fresh for the next student unless someone pressed Save. Start over clears the saved Bix after a confirm. Students never type anything.
- On a projector, the class can vote on each answer and on which strategy card to try.
- The tool says "practice helps" and never that the brain grows like a muscle. Studies of growth-mindset messages find small average effects, so the tool sticks to what is well supported: practice, new strategies and asking for help.
- Take three breaths is one quick pause, not a calm-down activity. If a student is upset, the school counselor is the right next step.
- Bix, the puzzles, the goal board and the locker are drawn in code. Every Light Mat and Number Lift puzzle was checked to be solvable in its listed fewest moves.
