Lesson 10
Conozcamos el tablero de 10
Warmup: Observa y pregúntate: Dedos y tableros de 5 (10 minutes)
Narrative
The purpose of this warmup is to elicit the idea that fingers and 5frames both show 10 in 2 groups of 5, which will be useful when students use 5frames to create a 10frame and represent quantities on 10frames in later activities.

 “¿Qué tienen en común los dedos y las fichas que hay en los tableros de 5?” // “How are the fingers and the counters on 5frames the same?” (Each hand has 5 fingers. Each 5frame has 5 counters. There are 10 fingers and 10 counters.)
Activity 1: Conozcamos los tableros de 10 (15 minutes)
Narrative
The purpose of this activity is for students to represent quantities between 5 and 10 using 5frames. Students cut out and put together 5frames to create a representation of a given number. The images in the student responses look like 10frames but students may put the 5frames together in creative ways or take parts of more than two 5frames. Students may choose to use one 5frame and draw additional circles to form the number. In the activity synthesis, students see and discuss a 10frame for the first time. If needed, the 5frames can be cut out for students before the activity.
Launch
 Groups of 2
 Give each student a copy of the 5frames to cut out, glue, and scissors.
 “Formen cada número. Si les ayuda, recorten los tableros de 5 para formar cada número” // “Make each number. You can cut out the 5frames to help you make each number.”
Activity
 8 minutes: partner work time
 Monitor for students who glue two 5frames, one right above the other.

Activity Synthesis
 Invite previously identified students to share their 5frames for 9.
 “Hoy vamos a empezar a usar una herramienta nueva que se llama ‘tablero de 10’. En él caben 10 fichas y nos ayuda a organizar y a mostrar números. Un tablero de 10 es dos tableros de 5 unidos” // “Today we are going to start using a new tool called a 10frame. It holds 10 counters and helps us organize and show numbers. A 10frame is two 5frames put together.”

Activity 2: Números con los dedos y tableros de 10 (10 minutes)
Narrative
The purpose of this activity is for students to gain familiarity with the 10frame by showing different numbers on it. While students may arrange the counters on the 10frame in many different ways, the structure of the fingers, with 5 on one hand and some more on another hand, encourages students to think about the 10frame as 2 groups of 5.
The purpose of the activity synthesis is to highlight the convention of filling out the 10frame from top to bottom and left to right. This allows students to see numbers 6–10 in relation to 5 and also makes it easy to determine how many squares are empty. While students may organize their counters differently, representations students see will be organized this way to emphasize the structure of the tool. In addition, moving from left to right and from top to bottom aligns with and reinforces the way children learn to read.

 Display 10frames filled as shown:
 “¿En qué se parecen estos tableros de 10? ¿En qué son diferentes?” // “What is the same about these 10frames? What is different?” (They both show 6 counters. They both have one full row and one counter in the other row. The top one has a full top row and the bottom one has a full bottom row.)
 “En las imágenes que vamos a usar en clase, vamos a llenar primero la fila de arriba, de izquierda a derecha. Después, llenamos la fila de abajo, también de izquierda a derecha” // “In the images that we’ll use in class, we will fill the top row first, from left to right, and then go to the bottom row and fill it from left to right.”
 Display 10frame filled as shown:
 “Vamos a mostrar 7 así” // “This is how we’ll show 7.”
