Hi everyone! I created a set of bulletin board trifolds. This trifold includes xy value table, T-table, rate of change, slopes, graphing linear equation by using slope intercept form, find slope from 2 points, x and y intercepts, and real word application problem. There is also a copy for class activity where students can use the slides or the physical poster to fill in the blanks.You can keep reusing year after year if you glue it onto a presentation board and put a new one up for each unit.
