how do you explain that to a 4th grader

Answer 3

10 -> ten
100 -> one hundred
1,000 -> 1 thousand
10,000 -> ten thousand
100,000-> hundred thousand
1,000,000 -> million
10,000,000-> ten million
100,000,000 -> hundred million
let them observe the naming pattern :D
(PS i dunno what 4th grader is, sorry :( )
