Arusha Hollister was a senior author on Investigations 3, writing units for grades 3-5, and is now writing online professional development for the 3rd edition. When she joined TERC in 2003, she worked with Susan Jo Russell on the 2nd edition data units. She went on to author a number of different 2nd edition units, at a variety of grade levels. While working on the 2nd edition, Arusha also developed Investigations Unit Workshops for the Boston Public Schools and led professional development for teacher leaders, to enable them to lead workshops for their colleagues. After the publication of the 2nd edition she developed in-person and online professional development for the Investigations Workshops project. Arusha also wrote several chapters of Judy Storeygard’s book, My Kids Can. These chapters are viewing guides for the accompanying DVD cases, which are focused on supporting students who are struggling with mathematics. Before working at TERC, Arusha was an elementary school classroom teacher in New York City and Boston, and a math coach in the Boston Public Schools.
