As someone who celebrates 100 days of school with her class every year. This is neat. I like the middle version of tally marks seems like a very simple way to group things in fives and tens in a more organized way. Probably handier to write out as well. I would much rather use the box method to write out 100. Lol

@DrWatson The other way, which uses far fewer sticks, is to make the bundle up to nine, put what would be its tenth aside, dismantle that bundle and start a new one.
So each iteration imports only one new stick, and the count is those put aside time ten, plus any in an uncompleted bundle .
I have used this system, both with sticks and with pebbles. I've also seen a neat version using metal rings on two bars, like a basic abacus. If I use a written tally I'd use the "five-barred gate" drawings.
