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!).
For example,
1-2-3-4-5-6-buzz-8-9-10-11-12-13-buzz-15-16-buzz-18, etc…
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.
