Here's what my sister told me: "I had 50cents in my pocket. I went to the school store to buy a pencil. I waited in line to be called forth. The teacher, who was black, took my money and asked me "How much is this?", as I took my time to figure how much I had she abruptly asked me but with a more aggressive tone, "How much is this!?", so I got scared and answered "75cents?", she responded again with the same tone, "No! These are 2 quarters, which is 50cents! Go get what your gonna buy.", so I got the pencil and came back and she asked me again "How much is this??", I responded "50 cents.." , then she told me "You know I can take this money away from you and not let you take anything right!? Who's your teacher?" , i said "Mrs. K", and then the lady told me "Oh my god. You're in the 4th grade and you can't even count money?!...Go to your class." and so I did."
I used a different name for my sisters teacher for security reasons.
My sister is 9 and she's not good at counting money/math.
She is afraid of going back to the school store and afraid of confronting this teacher again.
What can I do? What are my options? Can I get this teacher fired for such event?
