Reading can provide lots of fun for children and teens during summer vacation. Children who read during the summer are better prepared for school when they return to classes in the fall. Public libraries throughout Wisconsin will host summer events to encourage children and young adults to include reading in their summer fun.

The Milwaukee Public Library will host its 2007 Summer Reading Club for kids from 3 to 18. Signing up starts on June 1 at all Milwaukee public libraries and bookmobile sites.

Children aged 6 to 12 are invited to become “All Star Readers” at the Milwaukee library when they sign up for the Summer Reading Club. Children can score a point by reading 10 books or 1,000 pages. When they reach the reading goal, they will win a bag full of prizes.

●Sparkey Spots the Ball

Children up to 5 years old can join the read-to-me club, “Sparkey Spots the Ball”.
