The intent of this section of the NGSS appendices is more limited—to describe what each of these eight practices implies about what students can do. Its purpose is to enable readers to better understand the performance expectations. The “Practices Matrix” is included, which lists the specific capabilities included in each practice for each grade band (K-2, 3-5, 6-8, 9-12).
