Here's a song that would be great for K.S.2 to sing at the end of a 'Mother's Day Assembly.' I'm sure the lyrics will strike a chord with all the Mothers in the audience and children will love the humour in the song not to mention the rap. If I was the teacher I would get the children to shout 'Happy Mother's Day' at the end of the song and the children to accompany themselves in the rap with classroom imstruments.
