You will need a defined space for this one if playing outside. It can be played in the classroom with all the furniture left as is, or you can re-arrange or remove the desks.
Students stand up and spread themselves around the space.
The teacher asks a question and selects someone to answer (e.g. first hand up.) If the answer is correct, the student takes a step. If they can reach another student to “tag” them, the tagged student is out and must sit down. Students may chose to step further away instead.
Continue until there is just one student left standing, or until the students become a little restless.
Variations: If no one who is standing can answer a question but someone who is out can answer correctly, then that student can rejoin the game.
A magnificent answer (e.g. full sentence, demonstrating newly taught structure or something else unexpected but wonderful) earns the right to take 2 steps.
