Lesson 1

Count and Add

Lesson Purpose

The purpose of this lesson is for students to count objects and relate counting to addition. 

Lesson Narrative

Students revisit counting collections, which is an activity introduced in kindergarten. Students count and represent objects in a way that makes sense to them. Students then count dots on two dot cubes to find the total. Together, they relate counting to addition, as the teacher writes expressions to represent the total number of dots on the two cubes (MP2). A 10-frame is provided as a blackline master. Students used 10-frames in kindergarten and may choose to use them throughout this section. Consider making copies on cardstock or laminating them so they can be used repeatedly.

Throughout the lesson, observe students for the look fors on the Section A Checkpoint Assessment, which can be used throughout the section.

Math Community

In the lesson synthesis, students discuss  what it means to be a part of a mathematical community. Prepare a space, such as a piece of poster paper, titled “Math Community”​ ​and a T-chart with the header “Doing Math.”​ ​Partition the column into two sections: students and teacher.
