My wife is a sixth grade science teacher in her sixteenth year. After taking inflation into account, she makes less now than she did as a first year teacher. Because she is so far into her career and is in her fifth year at her current school, she has been able to cut back on classroom expenses quite a bit. She probably spends only $500-750 per year. Part of this is that she has always taught at Title 1 (poor) schools and many students have no supplies. Even if they qualify for free supplies (from the school district or local churches or whatever) at the beginning of the year, the kids either lose them or never got them in the first place. The district (Fort Worth), on the other hand, is fairly decent about providing lab equipment and kits, so she only has to buy science supplies (chemicals) once or twice a year. She has to purchase consumable lab materials about once a month or so. (Think sugar that will be burned into carbon.) Everything that you see on her walls except the Promethean board, from charts to calendars, came from out of pocket. Even her desk chair came from out of our pocket. But she doesn't buy pens or pencils for her kids. She has classroom sets of scissors, glue sticks, map pencils, and journals (notebooks), only the last of which requires replenishing each year. Unlike some of y'all's kids' schools, there are no supply drives. Most of the parents do not or cannot provide for their own kids, let alone someone else's.
