HELPFUL HINT TO MARTINE: For $3,000 one can buy more mica, quartz and sulfur as well as gecko and snake food than it is possible to consume in a year. Shop elsewhere. Better yet, stop spending your own money and start teaching your students. I can guarantee that when public education did a better job of educating, teachers spent little if anything on such things.
Just how much supplies does it take to teach reading, english, math, geography and history? As for the sciences, perhaps a little extra is needed, but it's my contention that these fools waste more money than you and I could ever imagine.
In California, in some cases we spend over 1/3rd of the education budget in k-12 on the children of illegal immigrants. Funny how I don't hear teachers lamenting that.
