Thank you so much for visiting our website! We are in the middle of a site redesign which is now available for you to view at **http://curriculum.newvisions.org/math**

You will still be able to access this website at this address until April 10th, at which point http://math.newvisions.org will redirect you to our new curriculum website. If you want to continue accessing this legacy website thereafter, you will be able to do so until June 30th of this year.

Big Ideas are intended to support teachers in teaching to a larger idea for each week and to deliberately connect the day’s work to the goal for the week. Our theory is that mathematical ideas do not come in lesson-sized chunks; usually, they are larger. In the following video, Phil Daro shares how we should be teaching to chapters not lessons.

We have written the Big Ideas, and their corresponding evidence of student understanding, so that representations, such as visual patterns, graphs, tables, and equations, are woven across different units of study rather than being developed an isolated unit. Some Big Ideas are repeated but approached differently in different units. This is intended to support students in seeing connections between different areas of mathematics and in having multiple opportunities to develop fluency with these different representations.

Each Big Idea has resources aligned to it, including tasks that support instructional routines and tasks that support exploring the Big Idea as a whole. This guide provides information on how to use the more general Big Idea resources and this page describes our approach to instructional routines.
