DD12 was subject acclerated in math in 4th grade to 6th grade and then again in 6th grade into Algebra I. In the first acceleration there was some gaps to fill in and some speed to make up that took her all of about two weeks. The acceleration happened over midway through the year and she ended up as top in the 6th grade class. I am not sure about gaps in the Algebra I class as she basically taught herself with one other student. I had a chat with her Geometry teacher who thinks they will be able to fill in the gaps, if there are any, over the course of the year. I am so excited for DD to have a proper math class. (Although very nervous that this beautiful 12 year old is going into a 10th grade class with a bunch of 15 year old boys. She does not look 12) In fourth grade she was also subject accelerated into 7th grade spelling and vocabulary. She is not a perfect speller now but I am not sure what she is supppose to be able to spell in the beginning of 7th grade. I am also not that concerned as there is spell check and she can spell well enough!
