<p>^by 6th grade, heck by 2nd grade, a parent should check to see that the work is done and answer any questions the child may ask. They should NOT be making children re-do problems the kids missed. That does NOT help the student or the teacher understand where the knowledge base is. In this particular case the child is doing “mental math” that can’t be duplicated on tests. The child is clearly missing something and my guess is he is either getting answers from the back of the book or doesn’t understand the process to get to the answer even if he can figure out the answer in his head. Yes, in 6th grade the math is easy but it’s a building block for later work that is more complicated. If the child is not showing his work, then the teacher doesn’t know what he is doing wrong. Since there is a discrepancy between homework and tests the parents need to back off and let the teacher see what the problem is. If the parent isn’t teaching the child the right way to do that problem, that doesn’t help either.</p>
