Five grey and squeaky mice
Polite and especially nice
Eating some most delicious cheese (yum! yum!)
One jumped into a hat
To hide from a big old cat
Now there are four grey squeaky mice. Squeak squeak!
You may want to point out that when there were 2,3,4,5 they were mice. When we have only 1 it's a mouse. Then ask the children to help come up with a rhyme to put into the 2nd line. e.g. "who lived in his special house"
