My son is 6 and in a half-day K program. To this point, he's been all about reading (taught himself to read at 4 and is currently reading on 4th grade level). He's been showing interest in math over the last couple of months. I always did well in math but I will admit that it's not an area that I feel particularly confident in. I was always a reader/writer-type. Anyway, I started doing Bedtime Math with him a couple of months ago and he LOVES it. He was home sick last week (sick enough to be out of school but well enough to drive me crazy) and wanted to do math and in an impulsive moment I signed up for a month of ixl. He is loving it and has completed 20% of first grade math with no help from me. My questions: 1, How accurate is ixl with regard to math/grade? 2, is there something he might like more that he can do relatively independently? Thanks in advance!!
