This lesson can only be opened if you have the SMART TECHNOLOGIES Notebook Program. The lesson was created using the 2018 Ready Math New York CCLS Resource Book for Second Grade. Lesson 5 is titled Add Using Arrays. Ready Math suggested giving the quiz after Day 4. I added a Day 5 to practice the concepts found in the quiz, such as, looking for equations that match an array, and drawing arrays to match equations. I also included math fluency drills on skip counting by 2's and 5's to the beginning of the lesson.
