Sprint: Multiply and Divide by 10

This Fluency Activity is a part of the Lesson 1, Unit 1, Grade 4. Think of fluency as having three goals: Maintenance (staying sharp on previously learned skills), Preparation (targeted practice for the current lesson), Anticipation (skills that ensure that students are ready for the in-depth work of upcoming lessons). For the Place Value fluency activity, students may represent ones, etc., using counters rather than drawing. Others may benefit from the opportunity to practice simultaneously speaking and showing units.
