The COVID-19 pandemic disrupted learning across the world. As students are back in class, some are much more behind than others. In the United States, teachers are working hard to help students make up for missed learning. Many schools are judging individual students’ knowledge and making lesson plans especially for them. Richard Evans is a third-grade teacher in Niagara Falls, New York. Most of his students were sent home as kindergartners in March 2020. Many spent all of first grade learning from home. Problems did not end when schools reopened for second grade. There were face covering and social distancing requirements. And many were not used to spending full weeks of study in school.
