I am currently teaching middle school math summer school. I have two classes and a total of over 50 students combined. The students are required to have a binder for class so this graph paper with the holes pre-punched in it is perfect. It is very durable and does not rip easily. Also the graph lines are dark enough that you can see them but not too dark that they take away from the students' work done in pencil. I highly suggest purchasing this graph paper to all students and teachers.
Buy this great product in bulk in the hopes that your budding future math genius will actually do their homework and use it all up. Even if they don't if you have enough children one is bound to be a mathematical genius. Do the math. The odds are in your favor. Enough kids and one will use it all up as hobby paper. (Okay so maybe the hobby is folding up and making paper airplanes with it but it is still being used and their math teachers would be proud of your support.) If all else fails it's a great gift to give to Goodwill or to sell real cheap at your next garage sale in the hopes of supporting somebody else's mathematical genius. And don't give up on your own kid's ever. Even Einstein wasn't recognized for his gifts while he was still in school and he actually flunked out.
