I found a really good song and lyrics, esp really longer than original song. 하나=one 둘=two 셋=three .... 구백 아흔 아홉=nine-hundred -ninety -nine Although one, two , three...nine-hundred-ninety-nine don't correspond to only 하나, 둘 , 셋, 구백아흔아홉, you can use this when you count things' number. 하나면 하나지 둘이겠느냐~♬ (One is one. Do you think one is two?) 둘이면 둘이지 셋이겠느냐~~~♬ (Two is two. Do you think two is three?) 셋이면 셋이지 넷 아니야~♬ (Three is three, not four) 넷이면 넷이지 다섯아니야~~♬ (Four is four, not five) 랄라랄라 라라라라 랄라랄라라~~~~~~(x2) 여섯이면 여섯이지 일곱이될까~♬ (Six is six. Will it be seven?) 일곱이면 일곱이지 여덟이 될까~♬ 여덟이면 여덟이지 아홉아니야..♬ (Eight is eight, not nine.) 아홉이면 아홉이지 열아니야~♬ 랄라랄라 라라라라라 랄라랄라라~~~~~(x2) (Lalalala lalalalalala lalalalala) 열하나면 열하나지 열둘이될까~♬ 열둘이면 열둘이지 열셋이될까~♬ 열셋이면 열셋이지 열넷아니야~♬ 열넷이면 열넷이지 열다섯 아니야~♬ 랄라랄라 라라라라 랄라 랄라라~(x2) 열여섯이면 열여섯이지 열일곱이될까~ 열일곱이면 열일곱이지 열여덟이될까~ 열여덟이면 열여덟이지 열아홉아니야~

Not sure if this is exactly what you want, but I thought you might want to check this out; there's an application called "너도나도 숫자놀이" which is for kids. https://play.google.com/store/apps/details?id=com.startline.funnycounting

I'd like to know too D: I try to practise numbers everyday, every evening when I exercise I count exercises in korean... I still can't remember well! Numbers are really hard to remember for me >.<
