The purpose of this activity is for students to make a model of the classroom, using solid shapes. To do this, students need to:

• Choose important objects to represent.
• Decide which shapes to use to represent the objects.
• Place the shapes appropriately to represent where things are in the classroom.

When students model a situation, using a representation such as a building made of blocks, they model with mathematics (MP4). The purpose of the Activity Synthesis is to share some of the objects students chose to represent and how they represented them.

Action and Expression: Internalize Executive Functions. Invite students to plan their model of the classroom. Ask students to think about what objects they are going to represent in their model and what solid shapes they will use to represent those objects.
Supports accessibility for: Organization, Conceptual Processing

If students are unsure which objects in the classroom to represent, consider asking:

• “Si tuvieras que contarle algo sobre tu salón a alguien que nunca lo ha visitado, ¿qué le dirías?” // “If you had to tell someone about our classroom who has never been here before, what would you tell them?” 
• Choose one object and ask, “¿Cómo podrías mostrar _____ con las figuras sólidas?” // “How could you show _____ with the solid shapes?”

• Invite selected students to share their classroom models.
• “¿Cuáles objetos del salón mostró ___?” // “Which objects in the classroom did ___ show?”
• “¿Qué figura usó ____ para mostrar un pupitre?” // “What shape did ____ use to show a desk?”

The purpose of this activity is for students to revise their classroom models. Students go on a Gallery Walk to see the models of their classmates. Describing their model to their peers and seeing other models helps students develop ideas for how to add to or change their model.

MLR8 Discussion Supports. During the Gallery Walk, invite students to ask “¿Qué me pueden contar sobre lo que hicieron? ¿Qué cosas del salón muestran las figuras?” // “Can you tell me about what you made? What do the shapes show from our classroom?” This gives all students an opportunity to produce language.
Advances: Conversing

• Invite selected students to share the changes that they made to their models and why they made them.
