I have a student who cannot grasp rounding. She really can't gasp math much at all. NO retention. She is in 4th grade. At the moment, she has an F in the subject. I hate Fs. Any ideas on how to help my student with this skill? At the moment, I am thinking about sending her to a third grade class during math. She needs the reteach. Not too sure how to help her achieve the grade level standards.
