# Lesson 1

Lo que sabemos sobre figuras

## Warm-up: Cuál es diferente: Osos de peluche (10 minutes)

### Narrative

The purpose of this warm-up is to introduce students to a new routine called Which One Doesn’t Belong. In this routine, students compare four different images and analyze the characteristics or attributes of the images. It gives the teacher an opportunity to hear how students use terminology and talk about characteristics of the items in comparison to one another. In this warm-up, students only work with three images of teddy bears. By the end of the section, students will compare four images of shapes. Emphasize to students that there is no right answer to the question and that it is important to explain their choice. Listen to how students create an argument and use or revise their language to make their argument clear to others (MP3, MP6).

### Launch

• Display the image.
• “¿En qué se parecen y en qué son diferentes los osos de peluche?” // “What is the same and what is different about the teddy bears?”
• 30 seconds: quiet think time
• 30 seconds: partner discussion
• Share responses.

### Activity

• “¿Cuál es diferente?” // “Which one doesn’t belong?”
• Display the image.
• 30 seconds: quiet think time
• Cuéntenle a su compañero cuál oso de peluche es diferente y por qué” // “Tell your partner which teddy bear doesn’t belong and why.”
• 30 seconds: partner discussion

### Student Facing

¿Cuál es diferente?

### Activity Synthesis

• Display the image of the white teddy bear with no heart and the image of the blue teddy bear with a heart.
• “Mai dijo que su oso de peluche es diferente porque no tiene un corazón en los brazos. Diego dice que su oso de peluche es diferente porque es azúl, no blanco. ¿Qué piensan?” // “Mai said that this teddy bear doesn’t belong because it’s not holding a heart. Diego said that this teddy bear doesn’t belong because it is blue, not white. What do you think?” (I think that Mai is correct because both of the other teddy bears have hearts. I think that Diego is correct because both of the other teddy bears are white. They are both correct.)
• If needed, say “Hay más de una respuesta correcta. Podemos encontrar razones por las que cada oso de peluche es diferente” // “There is more than one correct answer. We can find reasons why each teddy bear doesn’t belong.”

## Activity 1: Conozcamos “Libros de imágenes: Encuentra figuras” (15 minutes)

### Narrative

The purpose of this activity is to introduce students to stage 3 of the Picture Books center. Students recognize and describe illustrations and shapes in picture books. Students are not expected to use a recording sheet for this stage in kindergarten. When choosing a picture book for this activity, choose a book with illustrations that include examples of common, recognizable shapes. If students have not heard the story this year, read the book aloud to students as a part of the launch. After hearing the story at least once and making sense of the context, students experience the story again with a focus on describing illustrations and recognizing shapes. If needed, point to a shape in the book and ask, “¿Cómo describirían esto?” // “How would you describe this?” to encourage them to mathematize the situation. Some examples of picture books include:

• Grandma’s Purse by Vanessa Brantlet-Newton
• My Heart Fills with Happiness by Monique Gray Smith
• Pablo’s Tree by Pat Mora
• Saturday by Oge Mora
• There is a Bird on Your Head by Mo Willems
• Last Stop on Market Street by Matt de la Peña
• Miss Bindergarten Gets Ready for Kindergarten by Joseph Slate
• Big Red Lollipop by Rukhsana Khan
• Count on Me by Miguel Tanco
• The Girl with the Parrot on Her Head by Daisy Hirst
Action and Expression: Develop Expression and Communication. Synthesis: Students might benefit from alternative options to express their answer to the question “¿Qué saben sobre estas figuras?” // “What do you know about these shapes?” Invite students to draw what they know before they verbally share or to use gestures to show what they know about the shapes.
Supports accessibility for: Language, Conceptual Processing

## Activity 2: Figuras en una imagen (10 minutes)

### Narrative

The purpose of this activity is for students to recognize and describe shapes in a picture. As students discuss the shapes they notice, they use informal language and have the chance to learn more from their partner about how shapes can be described.
