I am a retired elementary teacher. I have a 12 year old (6th grade) and an 8 year old (3rd grade). (yes I am retired at 38). In Alberta where I am from there are the Provincial Exams for grades 3,6 and 9 (much like your FCAT). So i have some experience around that. Iwill give you the same advice I used to give my parents.
STOP THE STUDYING NOW. All this attention, all this presure,it is too much for her. OMG She is in the 3rd grade. What is she going to be like with the stress of the 6th grade? Or high school? OMG can you imagine what kind of wreck she will be in college!
You have a wonderful teachable moment here. It is up to you what you do with it.
Let her know that this test (like most she will have in her life) is truly not that important.
Let her know that it is just a pen and paper thing, it does not determine her overall success in life.
She must know that this does not determine her likeability in life.
This test does not reflect her goodness, her kindness and her spirit.
The test has no relation to how much she is loved.
The test does not determine how nice of a person she is, how many people like her and how she is able to help people.
The test does not in any way shape or form make her a better or worse person. This test just is. Only she can determine what kind of person she will be. She can be strong and move forward or she can be broken and afraid.
AH, but this test, this worrying can easily make her a worse person The constant pressure, the stress, that can make for a worse child.
This is your moment as a mom to shine. Teach her. Teach her now. You only get one chance to make this second count...and this one...and this one...
