ATI Content Specialist Recognized in Illustrative Mathematics Task Writing Contest

ATI wishes to congratulate Aaron Stidham, an ATI Content Specialist in Mathematics, for having his work selected for the Illustrative Mathematics Task Writing Contest. Illustrative Mathematics is a project of Dr. Bill McCallum, the Math Team Coordinator for Common Core State Standards. The purpose of the Illustrative Math web site is described as:

“Illustrative Mathematics will provide guidance to states, assessment consortia, testing companies, and curriculum developers by illustrating the range and types of mathematical work that students will experience in a faithful implementation of the Common Core State Standards, and by publishing other tools that support implementation of the standards.”

Aaron submitted a task of comparing volumes of aquariums using cross-sections to determine if the volumes were equal. His task has been judged to be an effective illustration of the high school math standard G-GMD 2: Give an informal argument using Cavalieri's principle for the formulas for the volume of a sphere and other solid figures. Aaron's example is scheduled to be placed on the site soon, and a link will be posted here once it is published.

Aaron also has submitted an additional example illustrating F-BF3: Build new functions from existing functions, still under consideration for inclusion.

We are proud of Aaron's commitment to promoting educational quality through clear and illustrative examples that assist educators in implementing Common Core State Standards-aligned materials for the benefit of their students. Aaron and the other members of our math content team at ATI are committed to continuing ATI's outstanding service to our educational partners as we all transition to Common Core State Standards.
