If there's some time to spare after a lesson, I could play the following games with my class:
Classic Pictionary
Two teams. Guess the secret word from a drawing on the board.
Paper hoops
Using cups/containers of different sizes, give the students a paper ball to try to make it in from a distance. They get three attempts. The smaller the cup/container, the more points they get.
Line up challenge
Divide the students in two teams and have them line up by shoe size, height etc. without talking.
Sticky note race
Divide the students into 3 teams and write different categories on the board. Let one person from each team draw something from that category and race to put it on the board. First place gets 3 points, 2nd, 1 point and 3rd, zero points.
Guess the classmate
A student sits in the middle of the classroom blindfolded and guesses who yells their name at random.
Continent challenge
Arrange seven different stations around the classroom representing the seven different continents around the world and have the students go to whatever station they think the country mentioned belongs to.
Geoguessr
Pull up geoguessr on your computer and let the students guess where the place is.
I spy
Classic game of I spy using classroom objects.
