In previous lessons, students counted two groups to find the total. They heard and used addition language such as ”put together,” “altogether,” “total,” and “2 and 3 is 5.” In this lesson, students begin with 1 group of counters and add more. They count to find the total number of counters. Students continue to hear and use addition language in this lesson.
Representation
MLR8
Comprehend (in spoken language) the term “count out” refers to making a group with a given number of objects.
Generalize (orally) that the phrase “add _____ more” means put that many more objects or images in a given group.
Use objects to represent adding on to an existing group of objects. Determine the total number of objects.
Cut out enough 5-frames to make a chart with a space for each student to answer the survey question.
Each group of 2 needs 1 connecting cube.

Teacher Reflection Questions
Think about who volunteered to share their thinking with the class today. Are the same students always volunteering, while some students never offer to share? What can you do to help the class understand the value of hearing the ideas of every mathematician?

K.CC.B.5
Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
Represent addition and subtraction with objects, fingers, mental images, drawingsDrawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
