Targeted Math Interventions: Double-Digit Addition without Regrouping was designed to help students quickly and easily master double-digit addition! The lessons are based on the direct instruction concepts of model, lead, and assess and are aligned to the Common Core State Standards in Number & Operations in Base Ten for grades 1 and 2. Each short lesson includes clear teaching instructions, review, multiple opportunities for modeling, and many scaffolded practice problems for students. The assessment at the end of the unit offers clear parameters to determine mastery. Extra practice worksheets are included for additional review prior to assessment or as a check-in at a later date. Over the course of four days, your students will go from adding double-digit numbers with guidance and support to independently demonstrating their newly developed skill!
