The 50th birthday celebration of Norman Bridwell’s iconic Clifford the Big Red Dog will kick off on September 24th at 10 am with a party at Scholastic’s New York City headquarters. And everybody can join in on the “Biggest Birthday Party Ever!” The live event will be streamed to classes across the country. Teachers can register now so their students can watch the festivities and Bridwell’s 30-minute webcast. There’s also a free kit that includes lesson plans, art project ideas, and coloring pages. In addition, Norman Bridwell’s Clifford Collection, six stories originally published between 1963 and 1977, will be released on the same day.
