Move-and-learn: games where the movement IS the vocabulary

Words that need the body

• Prepositions — obstacle course: on the chair, under the table, behind the door, next to the teddy. Camera-friendly: 'Put your hands ON your head / UNDER your chin.'
• Adverbs — walk slowly, jump quickly, whisper quietly, stomp loudly. Pairs of opposites in motion.
• Adjectives — be a HEAVY elephant, a LIGHT feather, a TALL giraffe, a SMALL mouse.
• Verbs of motion — the Actions pack acted out card by card: draw, act, guess, swap.

Structures for movement teaching

• Command chains — instructions grow: 'Jump. Jump twice. Jump twice and clap. Jump twice, clap, and say BLUE.' Working memory training in disguise.
• Opposite mirror — you say slow, they move FAST; you say big, they go SMALL. Comprehension check with built-in comedy.
• Freeze quiz — dance; on freeze, answer one question; dance resumes. Movement is the reward for language.

When the camera can count the jumps

Over a webcam, all of this is verified by guesswork: eight children in eight rooms, and "Jump twice and clap!" is checked against whichever two faces you happen to be looking at. That guesswork is starting to disappear. AI motion tracking reads an ordinary camera feed and counts repetitions — jumps, squats, arm raises — while judging whether the movement is really being done; fitness apps build it in through SDKs such as KinesteX, which runs a demo straight in a browser tab. Nobody has pointed it at language teaching yet. The day somebody does, "Jump twice, clap, and say BLUE" becomes a command the screen itself can mark.
