Although DS scored >90% on the end-of-year test for 4th grade math, his teacher was doubtful that the four weeks DS spent completing 4th grade math over the summer was sufficient. To help ease his concerns, we agreed to have DS take each chapter test in advance of the class beginning that section so that he could demonstrate proficiency on a chapter-by-chapter basis. It's not extra work because DS is using ALEKS in the class room, and it does not provide chapter testing -- so instead of taking 5th grade tests, he's taking 4th grade.
DS has matched the pace for 5th, completing it within the same time frame as 3rd & 4th. But because the teacher now sees the related homework & quizzes -- and the on-line work takes place under his nose in the classroom -- he seems satisfied with the progress.
