The Earlier/Later Time game (or call it Before/After or something else you think appropriate)
This is a variation on that Price Is Right "Higher/Lower" game. In that game, there is a price for an item that you must find. Say the item is a new TV for $1000. You start out saying $800, then the host says "Higher" so you say $1200 and the host says "lower." Then you keep going until you get the right price or until time runs out.
On this variation, you're teaching time, so just have a time for them to guess. Like "I wake up at ___ [7:40]." The student guesses 7:00 and you say "Later" [or "After"], they guess 8:00 and you say "Earlier" [or "Before"]. Keep going until they guess it or until time runs out.
You can set the time according to your class. Some students may be able to handle 30 seconds, others may need 1 minute. Just demonstrate it first and it should be fine.
