skip count song - Hi Niki,

I teach grade one, but I am sure this song will work for any grade. We sing:

skip count, skip count, count by 2's
skip count, skip count, count by 2's
skip count, skip count, count by 2's
we can count to 20 (and you could use any number here)

skip count, skip count, count by 5's
skip count, skip count, count by 5's
skip count, skip count, count by 5's
we can count to 50

skip count, skip count, count by 10's
skip count, skip count, count by 10's
skip count, skip count, count by 10's
we can count to 100

Naturally, I cannot tell you the tune. Use whatever tune you wish!!

Happy skip counting!!
