This Fluency Activity is a part of the Lesson 15, Unit 7, Grade 4. In Topic D, all homework pages are designed to become part of the take-home summer folder, created in this lesson. Therefore, students will only complete the top portion of each homework page and use the bottom portion as extra practice during the summer, inserting it into their mini-personal white boards. Although the homework does not directly reflect the work on each lesson's Problem Set, the work is directly related to the lesson and Grade 4 standards. Today's lesson is the first of four in the Fourth Grade Project. Each lesson involves the creation of an activity page that is later placed in a take-home summer folder.
