Lesson 11
Center Day 2 (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 4 of the How Close center. In this new stage, called Add to 1,000, students pick 8 digit cards and then choose 6 of those to make an expression that yields a number as close as possible to the target number, 1,000. In Activity 2, students learn stage 8 of the Five in a Row center, Add within 1,000 with Composing, and then choose to continue working on Five in a Row, or choose between two previously introduced centers focused on addition with three-digit numbers.
