Día 1 de centros (optional)

### Lesson Purpose

The purpose of this lesson is for students to practice adding numbers within 1,000.

### Lesson Narrative

This lesson is optional because it is an opportunity for extra practice that not all classes may need. In Activity 1, students learn stage 7 of the Five in a Row: Addition and Subtraction center. In this new stage, students add within 1,000 without composing. In Activity 2, students choose to continue working on Five in a Row, or choose between two previously introduced centers focused on place value in three-digit numbers.
