This book is an informational book which is suitable for elder kids. It uses the example of selling the lemonade to explain the relationship between supply and demand. the illustration is attractive, but the way of telling the information is a little bit dull. Can be used for social study and math class. ( )

This is a good example of an information book because it teaches students the relationship between demand and supply. It is not easy to explain the meanings of some economic terms; however, this book creates scenarios that make children have the experience of being a businessman. This book is very suitable for children from the fourth grade and above. Teachers can read the book use students. What's more, teachers can let students sell things and count their variable cost, profit and so on. This book inspires me to have fun ways to teach new concepts to children. ( )

This is not an easy concept to address in picture book format, but David A. Adler (and illustrator Edward Miller) have done a great job. Using the classic lemonade stand as an example, he explains the four basic rules of supply and demand:

1. When demand goes up and supply does not, prices go up (you didn't make enough lemonade on a hot day)
2. When demand goes down and supply stays the same, prices go down (the weather turns cold and no one wants lemonade)
3. When supply increases and demand does not, prices go down (Julie opened a competing lemonade stand)
4. When supply decreases and demand stays the same, prices go up(you didn't make a lot of lemonade, and Julie's stand isn't open)

Perfect for teachers!
