In a previous lesson, students subitized, or determined how many without counting, small groups of things in picture books. In this lesson, students continue their work with subitizing as they recognize and name small groups of up to 4 objects in the classroom without counting. Although some students may count to determine how many in larger groups of objects, the focus is on finding small groups of objects that can be recognized and named without counting. This lesson helps students gain familiarity with their classroom and encourages them to mathematize their environment (MP4).

In a future lesson, students will create their own picture books to show quantities that they identified in the classroom.

Were you able to circulate and hear student thinking while students worked in centers? If so, what routines or structures helped students work independently? If not, what routines or structures can you establish to ensure that you are able to circulate and talk to students as they work?
