About this Lesson

This lesson focuses on K.OA.A.3 Students engage in a game and collaborative problem-solving activities during which they represent different decompositions of numbers less than 10 by using manipulatives, drawings, and equations. This lesson contains strong examples of Core Actions 2 and 3. 

This video shows a real-life classroom, with all the real-life challenges and successes found in daily interactions between students and teachers. It has been selected because it includes illustrations of the Core Actions and Indicators embedded in the day-to-day work happening in schools, and so it offers opportunities to practice using and norming expectations around the Instructional Practice Guide: Coaching Tool. Learn more about this video and others in the collection.
