**How to Use Knowing Mathematics**

We suggest three different ways in which to use **Knowing Mathematics**.
No matter what model is used, lessons need 40 to 50 minutes each day.
For most lessons, we suggest that you spend about two fifths of the time on the instruction page and three fifths on the exercise page.
To fit the school day well, you may split daily instruction into two segments.

Remember that this is a small-group project.
For the pullout model and extended-day model, we suggest that you have not more than eight students, while four to six will be an ideal size.
For the summer-school model, we suggest that you have no more than twelve students.
