## Activity 1: Hagamos libros de números (30 minutes)

### Narrative

The purpose of this activity is for students to create a number book about their school community. Students share their work with a partner, receive feedback, and then improve their work (MP3). In the activity synthesis, students will create a title and front cover for their book. As students work during the activity, have them leave the first page blank. If time allows, invite students to make a rough draft and then a final draft of their book.

MLR8 Discussion Supports. Create a visual display of a page with a number, a picture, and some words or a sentence. Reference the display during the directions, pointing to each component.
Engagement: Internalize Self-Regulation. Provide students an opportunity to self-assess and reflect on their pages. For example, students should verify that each page has a number, a picture, and some words or a sentence.
Supports accessibility for: Memory, Organization
