This poster can be used to track behavior points as students gain or lose them each day (or whatever time interval you choose).
Enlarge one or two pages to poster size large enough to use, with small circular magnets, on magnetic board. Laminate. With a wet-erase marker, write each student's name next to their assigned number. Attach to magnetic board. Magnets should be reset to zero each day (or whatever time interval you choose).
Explain to students that this is a number line and that their magnets will be moved according to their behavior. Moving to the right adds points. Moving to the left subtracts or deducts points.
Use: If a student has outstanding behavior, move their magnet to the right one interval. If a student exhibits bad behavior, move their magnet to the left one interval. At the end of the day (or whatever time interval you choose), students note what number they are on and add (if a positive number) or subtract/deduct (if a negative number) that number of points from their behavior point total.
(My free Behavior Bank Book can be used by students to keep track of their points.)
This method gives students practice adding and subtracting numbers, allowing them to build fluency. It also gives them an early understanding of the number line and negative numbers.
