How Would We Count?

Stage: 1 and 2 Challenge Level: Challenge Level:1
Kai from Carrillo School in America sent in the following:

You can count them by rows. To be specific, you can cluster then into rows and count them, in the first row there is 2. Then if you keep on counting, you will get 23. Also, you put them into groups of 3 or any other friendly number and the leftovers, you count them up and then you put it like this, 5 plus 5 plus 5 plus 5 plus the leftover 3 then you evaluate it to get 23.
thank you
