Lesson 10
Contemos historias sobre nuestra escuela
Warm-up: Observa y pregúntate: Burbujas en el parque (10 minutes)
Narrative
The purpose of this warm-up is to elicit the idea that we can notice math in everyday situations, which will be useful when students tell story problems about their school community in a later activity. While students may notice and wonder many things about this image, questions that students develop about the image are the important discussion points.
Consider using a picture of your own school community that students can tell stories about, in place of the image in the book.
Launch
- Groups of 2
- Display the image.
- “¿Qué observan? ¿Qué se preguntan?” // “What do you notice? What do you wonder?”
- 1 minute: quiet think time
Activity
- “Discutan con su compañero lo que pensaron” // “Discuss your thinking with your partner.”

Activity 1: Lluvia de ideas sobre problemas-historia (15 minutes)
Narrative
The purpose of this activity is for students to develop ideas for story problems that they can write about their classroom, school, or community. In the next activities, students will develop, share, and solve their own story problems (MP2, MP4).
This activity can be completed in a different area as previous walks. For example, this walk can focus on the playground or outside environment or take place in one area of the school, such as the library.
