This Fluency Activity is a part of the Lesson 29, Unit 4, Grade 1. Excitement should be building in this third consecutive day of core fluency practice. Students have had two days and on this third day have the chance to look back at their progress. Students who completed all questions correctly on their most recent Practice Set should be given the next level of difficulty. All other students should try to improve their scores on their current levels. Students complete as many problems as they can in 90 seconds.
