Someone mentioned frustration when their child actually does encounter challenging work. This EXACTLY. My DD (6) who skipped a year is still not challenged enough consistently. They'll give her grade level where she flies through then give her accelerated and she expects to fly through too and gets frustrated and mad when she can't. Even if the concept is easy for her (which she figures out once someone calms her down and explains this every time). Getting used to "coasting" and never working would be my concern as yes, eventually she will need to work hard. Whether that's college or high school. Eventually she will face a challenge in math and will need to have the emotional and mental tools to work though a challenge.
