What you see isn't what you get

What you see isn't what you get The advertisement shows a book like board that a child can manipulate the fraction pieces. What you get is a small cardboard 5 by 8 folded board with 2 sheets of fraction pieces, which most are too small for little fingers . This is from someone who has been in math education for over 36 years .
