Dear Parents, As you are already aware, our report card is now a standards-based report in all subjects. I would like to clarify what this means for mathematics. The indicators of Mathematics Development are organized into six strands. These strands remain constant throughout your child’s K-5 math experience, while the grade level goals change from one year to the next, building upon the skills from the previous years. The grade level expectations for each strand are listed below. While they are measured and assessed throughout the year, their attainment is an end of the year expectation. The various assessments used by your child’s teacher, as well as district assessments will help you gauge your child’s progress toward attainment of these goals. It is hoped that the goals will guide your understanding of your child’s grade level mathematical experience. Please note that the numbers below correspond to the numbered content goals on your child’s report card.
