The purpose of this lesson is for students to count to find the total number of images in 2 scattered groups.
In previous lessons, students have counted to find the total number of objects in 2 groups and the total number of images in 2 organized groups. In this lesson, students continue to put together 2 groups in order to find the total. The focus of the lesson synthesis is on keeping track of images that have been counted so each image is counted once and only once. This is the first lesson where students participate in a cool-down after the lesson synthesis.
