# Pete the Cat and His Four Groovy Buttons by Eric Litwin and James Dean

Pete the Cat is fun and loveable. At 8am, Pete puts on his favorite shirt with 4 groovy buttons. His buttons inspire him to sing, “My button, my buttons, my four groovy buttons, my buttons, my buttons, my four groovy buttons.” But as he goes about his day, one-by-one his buttons pop off his shirt. Does Pete cry? No, he keeps going and keeps singing his song. This book has lot of fun math in it as Pete counts down his buttons from 4 to 0. The song he sings repeats in a predictable way (a pattern) as the number of buttons goes down by one each time. The illustrator includes the subtraction equation (such as, 4 – 1 = 3) as each button pops off. You can show the children the equation and explain that they will learn to write mathematical equations like that in kindergarten. Children can draw their own shirt pictures and glue dots on them for buttons. Then they can write on them the number of buttons they have. For example, “I have 5 buttons on my blue shirt. If I lose one, I’ll have 4!”
