# Lesson 10

Juntemos fichas geométricas

## Warm-up: Observa y pregúntate: Edredones (10 minutes)

### Narrative

The purpose of this warm-up is to elicit the idea that shapes can be combined to make patterns and pictures, which will be useful when students put together pattern blocks to make shapes in a later activity. While students may notice and wonder many things about these images, the shapes in the design of the quilt are the important discussion points.

The images in this warm-up are of quilts made by a group of women in Gee’s Bend, Alabama. Consider reading the book “Stitchin’ and Pullin’: A Gee’s Bend Quilt” by Patricia McKissack and showing students more examples of quilts as a part of the Notice and Wonder activity. Examples of quilts from the book that are made of different shapes than the one shown in the student workbook will give students the opportunity to notice and wonder different things.

### Launch

• Groups of 2
• Display the image.
• “¿Qué observan? ¿Qué se preguntan?” // “What do you notice? What do you wonder?”
• 30 seconds: quiet think time

### Activity

• “Discutan con su pareja lo que pensaron” // “Discuss your thinking with your partner.”
• 1 minute: partner discussion
• Share and record responses.

### Student Facing

### Activity Synthesis

• Display the image:
• Consider displaying images of other quilts from this website: https://www.soulsgrowndeep.org/quilt-categories/patterns-geometry
• “Estas fotos muestran edredones que fueron hechos por mujeres de Gee's Bend, Alabama. ¿Qué figuras ven en los edredones?” // “These pictures show quilts that are made by women in Gee’s Bend, Alabama. What shapes do you see in the quilts?” (There are rectangles, squares, and circles.)
• “¿En qué parte ven figuras que se juntaron para formar otra figura?” // “Where do you see shapes that are put together to make another shape?” (There are a lot of rectangles that make a square. There are rectangles that are put together to make a bigger rectangle.)

## Activity 1: Conozcamos “Fichas geométricas: Cuenta separando y construye” (10 minutes)

### Narrative

The purpose of this activity is for students to learn stage 4 of the Pattern Blocks center within the context of the warm-up. Students put together pattern blocks to form larger shapes. Students practice recognizing written numbers and counting out a given number of objects. Students describe and compare the shapes that they create.

In this activity, students put together the pattern blocks to make their own quilt. Consider taking pictures of the designs that students create and combining them to make a class quilt. Students may or may not put the pattern blocks together to look like something specific, such as a boat or a square. The recording sheet is printed in the student book for this activity. The blackline master is available for students to use during center activities in future lessons.

MLR7 Compare and Connect. Synthesis: To amplify student language as they compare, contrast, and connect the shapes, encourage students to point to the relevant parts of the displays as they speak.
Representation: Internalize Comprehension. Invite students to line up the pattern blocks so that they can visually see which patterns blocks were used more.
Supports accessibility for: Visual-Spatial Processing, Conceptual Processing

• Pattern Blocks Stage 4 Recording Sheets, Spanish

### Launch

• Groups of 2
• “Muchas veces se busca juntar figuras para hacer prendas de vestir, cobijas, edredones y otras cosas. ¿Sus familias tienen o hacen cobijas o edredones especiales que tengan figuras? ¿Cómo los describirían?” // “Shapes are often put together to make things like clothes, blankets, and quilts. Does your family have or make any special blankets or quilts that have shapes on them? How would you describe them?”
• 30 seconds: quiet think time
• Share responses.
• Give each group of students pattern blocks.
• “Vamos a aprender una nueva forma de trabajar en el centro ‘Fichas geométricas’. Se llama ‘Cuenta separando y construye’. Van a contar y separar las fichas geométricas y las van a usar para hacer su propio patrón para un edredón” // “We are going to learn a new way to do the Pattern Blocks center. It is called Count Out and Build. You are going to count out the pattern blocks and use them to make your own pattern for a quilt.”
• Display the student book.
• “Los números me dicen cuántas fichas geométricas de cada tipo debo contar y separar. ¿Cuántas fichas anaranjadas en forma de cuadrado necesito?” // “The numbers tell me how many of each pattern block I need to count out. How many orange square pattern blocks do I need?” (4)
• 30 seconds: quiet think time
• Share responses.
• “Cuenten y separen las fichas geométricas. Después, junten sus fichas geométricas para hacer un patrón para un edredón. Díganle a su compañero lo que van a crear” // “Count out the pattern blocks. Then put your pattern blocks together to make a pattern for a quilt. Tell your partner about what you are making.”

### Activity

• 3 minutes: partner work time
• “Esta frase dice ‘Usé más _____ que _____’. Puedo hacer un dibujo de la ficha geométrica o escribir una palabra. Si uso más triángulos que cuadrados, puedo dibujar un triángulo en la primera línea y un cuadrado en la línea que sigue” // “This sentence says ‘I used more _____ than _____.’ I can draw a picture of the pattern block or write a word. If I use more triangles than squares, I can draw a triangle on the first line and a square on the next line.”
• Demonstrate drawing a triangle and a square.
• “Mi frase dice ‘Usé más triángulos que cuadrados’. Completa la frase acerca de tu edredón” // “My sentence says ‘I used more triangles than squares.’ Fill in the sentence about your quilt.”
• 2 minutes: independent work time
• If time, invite students to count out the pattern blocks listed on the second page and create another quilt.

### Activity Synthesis

• Invite students to share the shapes they made with pattern blocks.
• Display two student-created shapes.
• “¿Qué tienen en común las figuras? ¿En qué son diferentes?” // “What is the same about the shapes? What is different about them?” (Sample responses: They both have 3 green triangles. They used the same shapes but they put them together in a different way. One of them looks like it has a smiley face in the middle.)
• “¿Hay más fichas verdes en forma de triángulo o más fichas azules? ¿Cómo lo saben?” // “Are there more green triangle pattern blocks or blue pattern blocks? How do you know?”

## Activity 2: Rompecabezas de fichas geométricas (10 minutes)

### Narrative

The purpose of this activity is for students to use pattern blocks to fill in simple puzzles. Students need to be more precise in arranging the pattern blocks because the pattern blocks touch at the sides and corners. The puzzles are in black and white so that students are not able to determine which pattern block to use based only on color. The Pattern Block Puzzles blackline master is available for students to use during this activity.

When students make connections between the pattern blocks and the shape outlines in the puzzle, they show their ability to reason abstractly and quantitatively (MP2).
