My daughter and I ran across this game and it was harder than it sounds, but good practice on our multiples of 7s.
Take turns counting. For every number that is a multiple of 7 or has the digit 7, say BUZZ instead of the number. If you mess up, start all over. See if you can make it to 100 (or even higher!).
We kept messing up, so we pulled out the hundred chart and circled all the multiples of 7s. Then the numbers with a 7 digit.
There are endless variations of this game: different number of players, with or without the visual, different multiples, or with the squares or prime numbers.
