What are the Math Fluency Drills? Thanks so much for viewing my Kindergarten Fluency Drills packet! This packet contains 150 all-in-one fluency activities! The sheets build upon five sets of skills: numbers, missing number, subitizing, shapes and computation. Each of the skills come with 30 sheets. You can choose to place these skill sheets in a math center, RTI math intervention group, use whole-group, send home for homework or use for your early finishers. This packet requires very little prep
