I remember in primary school, the teachers had 2 group games.

The first had math questions on flashcards: like 2x4 or 5+3.
There was one line of kids against the blackboard and one line of kids against the windows. It was a race between the first kid in each line. If you said the correct answer first, you went to the back of the line and would have to have another question. If you lost, you sat down. The last one standing won.

The second was a geography game. Everyone stood up. The teacher named a country, river, etc. The first kid had to name a place that started with last letter of the teachers word and so on. If you couldn't name a place, you sat down. the last one standing won.

I remember waiting and worrying what letter I would have or in the case of math, going over and over the harder questions in my head... like 12x13.

the crazy thing is that the kids who needed the practice sat down first and could enjoy the 'show' and kids who didn't need the practice kept standing and getting more anxious

I used to go into the atlas and memorize obscure place names beginning with 'a' or 'r' in Europe so I wouldn't feel anxious waiting for my turn. It backfired on me, because I stood longer and eventually ran out of words anyway,
