Every set of 12 pages has been written to follow the instruction in roughly half a Bridges unit. Practice pages 1–12 can be used any time after Unit One, Session 12; pages 13–24 can be used any time after Unit One, Session 23; and so on. Recommended timings are noted at the top of each page.

Some of the problems on certain pages have been marked with a Challenge icon. These problems may not be appropriate for all the students in your classroom; consider assigning them selectively.
