Teacher/Classroom Calculators: Grades, PBIS & Planning Tools

How to use this collection

Use this collection to plan classroom supplies, rewards, PBIS routines, behavior data, intervention minutes, assignment or weighted grades, attendance, fluency, parent contacts, and seating groups. Start with roster size and the school routine you actually use.

Buying guidance

For classroom planning guidance, check grade-level expectations, school calendar, district policy, team routines, donation assumptions, supply restocks, and documentation rules before using an estimate with students or families.

Common mistakes

Common mistakes include forgetting midyear roster changes, mixing unlike progress-monitoring periods, using grade-category weights that do not total 100%, rounding differently than the gradebook, and launching reward systems that are too expensive to maintain.
