How do I know if there have been changes to the curriculum and if I have the most recent version?
Changes to the Curriculum
We maintain a
Unit Change Log online so that you can see if you have the most recent version of our curriculum and, if not, what changes have occurred since your publication date.
Generally, we try not to make any substantial changes to our curriculum. But, we are a literature-rich curriculum and are dependent on many publishers for the books we use. Changes to the curriculum are often due to books that go out of print. An exception to this rule is when we replaced the entire Concept 2 in the Age 6-8 curriculum in 2019. We added a full math program to that level and replaced the Measurement Concept 2 with Relationships. For those with older versions of that curriculum, we have the online student activity pages available for purchase so that you may have the pages that match the older version of the curriculum. We have also made available the student activity pages for the Age 5-7 curriculum printed before 2019 online for purchase.
