I wrote this booklet to help make it fun for my younger son to learn to recognize the number six.  Turquoise is his favorite color, so there's a little of that penned in.  The first batch of  the booklet was 20 copies, made for his classmates in Kindergarden.   I brought the booklet into the classroom for my son's VIP week, a special event where kids invite parents  to come in and read a story or make a craft, etc. The child also gets to pick a favorite snack and be line leader and other stuff like that.  After we read the booklet, all the kids tried out making a booklet about their favorite numbers, and it was really fun.
