Pete the Cat and His Four Groovy Buttons by Eric Litwin
Pete the cat loves his favourite shirt with its four groovy buttons. He even sings a song about them! But how will the song change as each button pops off and rolls away?
This story uses words and numerals to represent the numbers up to four, and subtraction number sentences are used to show what has happened each time a button pops off and rolls away. This story would make a lovely introduction to written subtraction.
