Star Math. Your child should be coming home with paper showing their last two Star Math test results. At the bottom you'll see two scores which represent your child's PR (percentile rank) Math score. A PR of 85 means your child performed better than 85% of other 4th graders nationally at this same point in the year. The kids are all working to earn a PR (Personal Record) on their PR (Percentile Rank). Those who did earned a special badge for this achievement today. Effort plays a bit part on this test which is why I included their answer sheet along with it so you could see their included work.
