The following resources were developed to support the 1st edition of Investigations.
- End-of-Unit Assessment Sourcebooks. (In the 2nd edition, all assessments are included in the units.)
- Ten-Minute Math. (The 2nd edition does not currently include a book that compiles all of the Ten-Minute Math activities at grades 3-5. However, each Classroom Routine or Ten-Minute Math activity is summarized in Implementing Investigations at Grade X.)
- Schools and Families. (This should continue to be a useful resource, as long as changes in content and philosophy of the 2nd edition are accounted for in work with parents and families.)
- Math Packs. (While not all of the games in these packs are included in the 2nd edition, and others have been revised, this should continue to be a useful resource.)
