One resource in many curricula

This summer, Ben builds a short bridge course, Math (Summer bridge), for students getting ready for Level 2. It needs no new Teach Books or Exit Tickets: some of Math's will do.

So Ben places Math's resources in the new curriculum's outline. Each new row points at the same resource Math's row points at, and nothing is copied. A resource can be placed in as many curricula as need it, and your tools can find every place it's placed in one go.

Try it: choose Lesson 1 Teach Book, then Lesson 2 Teach Book, and compare where each one is placed.

Lesson 1 Teach Book is one resource with two rows, one in each curriculum. When Ana fixes a mistake in it, both curricula get the fix, because neither row holds a copy. Lesson 2 Teach Book is only in Math, so a change to it reaches Math alone. Before you change a resource, this list tells you every curriculum the change will reach.
