This catchy song's excellent for practising reading, revising colours and prepositions of place, and introducing was/were to young pupils:
There was a blue fish in the pool,
Mum was scared, but I was cool.
There were green fish in my bed,
There was one on my mum's head.
Fish, fish, everywhere,
On the sofa, on the chair.
Quick, quick, Sue and Frank,
Get the fish back in the tank!
There was a pink fish on the mat,
It was really big and fat.
There were red fish on the floor,
Five or six, or maybe more.
Fish, fish, everywhere,...
