Following the events of The Last Colony, John Scalzi tells the story of the fight to maintain the unity of the human race. The people of Earth now know that the human Colonial Union has kept them ignorant of the dangerous universe around them. For generations the CU had defended humanity against hostile aliens, deliberately keeping Earth an ignorant backwater and a source of military recruits. Now the CU's secrets are known to all. Other alien races have come on the scene and formed a new alliance—an alliance against the Colonial Union. And they've invited the people of Earth to join them. For a shaken and betrayed Earth, the choice isn't obvious or easy. Against such possibilities, managing the survival of the Colonial Union won't be easy, either. It will take diplomatic finesse, political cunning...and a brilliant "B Team," centered on the resourceful Lieutenant Harry Wilson, that can be deployed to deal with the unpredictable and unexpected things the universe throws at you when you're struggling to preserve the unity of the human race. Being published online from January to April 2013 as a three-month digital serial, The Human Division will appear as a full-length novel of the Old Man's War universe, plus—for the first time in print—the first tale of Lieutenant Harry Wilson, and a coda that wasn't part of the digital serialization.

100 days of multiplication problems. Discover the difference a couple minutes of practice can make. These are reproducible practice sheets to help students learn their multiplication facts and recall them with fluidity. This book focuses on digits 0-12. An answer key is included in the back of this book, so students can easily check their own work.

Do your students suppose that 1/3 is greater than 1/2, since 3 is greater than 2? Do they believe that having “halves” means having two, and only two, congruent “pieces” of a whole? What tasks can you offer—what questions can you ask—to determine what your students know or don’t know—and move them forward in their thinking? This book focuses on the specialised pedagogical content knowledge that you need to teach fractions effectively in grades 3–5. The authors demonstrate how to use this multifaceted knowledge to address the big ideas and essential understandings that students must develop for success with fractions—not only in their current work, but also in higher-level mathematics and a myriad of real-world contexts. Explore rich, research-based strategies and tasks that show how students are reasoning about and making sense of fractions. Use the opportunities that these and similar tasks provide to build on their understanding while identifying and correcting misunderstandings that may be keeping them from taking the next steps in learning.
