While students across all grades have shown growth during the pandemic-related learning disruptions, that growth hasn’t kept pace with what we’d expect to see in a typical year. According to the most recent data, students in grades 2–8 have fallen an average of 11 percentile points below typical year expectations in math.
In terms of instructional time, it will take approximately 11 weeks to make up that lost ground, though it varies widely from grade to grade. Recouping an 11-percentile point drop in 2nd grade, for example, will require an estimated five weeks, while covering a similar drop in 6th grade will take more like 15 weeks.
The issue is that the math skills we expect students to master do not always increase linearly in terms of difficulty. If math standards and skills are a staircase, most of them are short, relatively uniform steps up—but every once in a while, we expect students to take big leaps in understanding and ability.…Read More
