Number combinations to 10 song

I've added the song words and backing track courtesy of youtube. The first 3 times we did this in class;I put the number combinations on the board for us to follow. I then removed random numbers; and the children were able to remember the missing numbers and carry on with the song. On the 5th attempt;I removed the words and the children sang it all way through. They LOVE it. On the word document I've shown you where the number combinations slot into the song.
