In our efforts to reform mathematics education, we've learned a tremendous amount about young students' strategies and the ways they construct knowledge, without fully understanding how to support such development over time. The Dutch do. So, funded by the NSF and Exxon Mobil, Mathematics in the City was begun, a collaborative inservice project that pooled the best thinking from both countries. In Young Mathematicians at Work, Catherine Fosnot and Maarten Dolk reveal what they learned after several years of intensive study in numerous urban classrooms. In this second volume in a series of three, Fosnot and Dolk focus on how to develop an understanding of multiplication and division in grades 3-5. Their book: describes and illustrates what it means to do and learn mathematics provides strategies to help teachers turn their classrooms into math workshops that encourage and reflect mathematizing examines several ways to engage and support children as they construct important strategies and big ideas related to multiplication takes a close look at the strategies and big ideas related to division defines modeling and provides examples of how learners construct models - with a discussion of the importance of context discusses what it means to calculate using number sense and whether or not algorithms should still be the goal of computation instruction describes how to strengthen performance and portfolio assessment emphasizes teachers as learners by encouraging them to see themselves as mathematicians.

On July 8th, 2015, something weird happened. The NYSE computers went down and trading was suspended for several hours. The culprit wasn't hackers or a rogue algorithm. It was just... a glitch. And it's just the beginning. Keith Landry has lived long enough to have seen the end of the cold war; a war fought without uniforms or rules, a war that has claimed his career and his soul. Now, he has come home to Spencerville, a town in the American heartland that is both familiar and strange, a town as tarnished as Landry himself. But for Landry, Spencerville has one attraction that time has not corrupted. Her name is Annie Prentis, and she had been the one pure love of his youth. Then came Vietnam, and a world gone crazy separated them. Annie had long since married Cliff Baxter, the town's chief of police and its most powerful man, an unfaithful, yet brutally possessive husband, a force more dangerous than any Landry has met on the fields of battle. Landry has vowed: No more violence. No more killing. But now he has to fight one final, unavoidable battle, a battle that will be both his deadliest and his most personal. Confronted with his last chance at redemption, he must violate his oath - calling on all of his skills learned from a lifetime in military and intelligence service to rescue Annie from her sadistic husband, a man equally skilled in the tactics and techniques of death. Landry knows he's got to act rationally and with deadly cunning. Faced with a simple, stark Young Mathematicians at Work: Constructing Multiplication and Division v. 2 free ebook choice - a new life, or no life at all - Landry takes the one critical step in the only direction he can: into the inevitable, explosive confrontation that will decide the fate of three people gripped in a fatal triangle.
