This project develops images, extended examples, and principles that illustrate how the articulation, representation and justification of general claims about operations evolve in the elementary grades and how this work supports the transition from arithmetic to algebra in the middle grades. A Sourcebook developed by staff and teacher-writers provides an account of this work across the school year in grades 1-6 and commentaries that help teachers consider the underlying pedagogical and mathematical aspects of the work. An online course uses the Sourcebook as a text to enegage teachers in implementing these ideas in their instruction.

该项目开发了图像、扩展示例和原理，以说明有关运算的一般主张的阐明、表示和论证如何在小学阶段发展，以及这项工作如何支持中学阶段从算术到代数的过渡。 由工作人员和教师作家编写的资料手册提供了 1-6 年级整个学年这项工作的说明，以及帮助教师考虑这项工作的基本教学和数学方面的评论。 在线课程使用资料手册作为文本，让教师在教学中实施这些想法。
