Module 1, Lesson 20 - Grade 1 Problem Set The worksheet above is from Eureka Math curriculum (sometimes known as Engage NY). We use these videos in my classroom to create an independent station so that I am free to help other students at another station. The videos are done in a way that scaffolds the students in their learning and understanding of each concept. You will notice that I start out doing the worksheet with them but then I start to leave spaces empty for the students to complete on their own to ensure that they are understanding each skill. You will hear at the end about putting these in the "Done Tub" or the "To Be Finished Tray". These are just two baskets that I have in my classroom where their papers go as needed.
