Lesson 11

Consigamos suficientes

Warm-up: Cuántos ves: En un instante (10 minutes)

Narrative

The purpose of this How Many Do You See is for students to recognize and name small groups of dots and describe how they see them. This is the first time the images are quickly flashed instead of being displayed for students to look at for as long as necessary. This encourages students to determine the number of dots without counting. From this point on, images in the How Many Do You See routine will be flashed rather than displayed.

MLR8 Discussion Supports. Use gestures to emphasize a countdown to when the image is flashed. This will help students learn the cues that require their attention.
Advances: Listening, Representing
Engagement: Provide Access by Recruiting Interest. Use a countdown such as “¡Preparados, listos, miren!” // “Ready, set, show!” to support student focus and attention. Reassure students who miss the first flash that the image will be shown a second time.
Supports accessibility for: Attention, Social-Emotional Functioning

Launch

  • Groups of 2
  • “Esta vez les mostraré un grupo de puntos muy rápidamente. Prepárense para ver cuántos puntos hay” // “This time I am going to show you a group of dots very quickly. Be ready to see how many dots there are.”
  • Flash the first image.
  • “¿Cuántos puntos vieron? ¿Cómo lo saben?, ¿qué vieron?” // “How many do you see? How do you see them?” 

Activity

  • Flash the image again.
  • “Usen sus dedos para mostrarle a su compañero cuántos puntos vieron” // “Use your fingers to show your partner how many dots you see.”
  • 30 seconds: partner work time
  • “Cuéntenle a su compañero cuántos puntos vieron, cómo lo saben y qué vieron” // “Tell your partner how many dots you see and how you see them.”
  • 1 minute: partner discussion
  • Repeat with the second image.

Activity 1: Actuémoslo: Cuatro ranitas manchadas (parte 2) (10 minutes)

Narrative

The purpose of this activity is for students to think of different ways a story can be represented. Students hear the story for the second time. In addition to explaining what the story is about, students also think of ways the class could act out the story. Acting out gives students opportunities to make sense of a context (MP1). Monitor for suggestions of acting out the story with concrete objects such as cubes, fingers, or students, as well as representing the story with pictures. In the activity synthesis, the class acts out the story in one of the ways suggested by the students. 

Launch

  • Groups of 2
  • Display and read the story.
  • “¿De qué se trata la historia?” // “What is the story about?”
  • 30 seconds: quiet think time
  • Share responses
  • Read the story again.
  • “¿Cómo pueden actuar esta historia?” // “How can you act out this story?”
  • 30 seconds: quiet think time

Activity

  • “Discutan con su compañero cómo pensaron” // “Discuss your thinking with your partner.”
  • 1 minute: partner discussion
  • Share responses. 

Student Facing

Frog.

4 ranitas manchadas se sentaron en un tronco manchado
a comer los más deliciosos bichos. ¡Yum! ¡Yum!
1 saltó al lago, que estaba agradable y fresco.
Ahora hay 3 ranitas verdes manchadas. ¡Glub! ¡Glub!

Activity 2: Consigamos suficientes (10 minutes)

Narrative

The purpose of this activity is for students to get enough pencils for each group of students. Students might get enough pencils for the groups by giving one pencil to each person in the group. Students may also notice that the number of students and pencils are the same when they make a group of pencils with one pencil for every student.
