Classroom Ball Chairs for 2nd Grade Classroom

Hi, my name is Ms. Hersey-Phillips. The students know me as Ms. H.P. I teach at Jackson Elementary in Plant City, Florida. Our school is at a 98% below poverty level socioeconomic status. I teach second grade and would like to use ball chairs in my classroom. They reduce children's restlessness and irritability, as well as improve posture. Our school can't afford to purchase these, as well as myself, so I am asking for help to purchase these ball chairs for my classroom. An 8-pack of chairs is $75.99. I want to get 3 packs. Any remaining money will go toward pencils, paper and erasers for the students.
