The purpose of this activity is for students to sort objects into categories and represent and compare the numbers of objects in each category.

• “En la siguiente actividad, ustedes van a comparar el número de chaquiras que hay en sus bolsas con el número de chaquiras que hay en la bolsa de su compañero” // “In the next activity, you will compare the numbers of beads in your bag to the numbers of beads in your partner’s bag.”

The purpose of this activity is for students to compare groups of up to 20 objects. This activity is optional, because the standards do not require students to compare groups of objects or written numbers beyond 10. Students can continue switching bags and counting, representing, and comparing sets of beads, as time permits.

• Invite previously identified students to share.
• “¿Cómo les ayudaron los dibujos a descifrar quién tenía más chaquiras en total?” // “How did the drawings help you figure out who had more beads altogether?”
• “¿Cómo les ayudaron los números a descifrar quién tenía más chaquiras en total?” // “How did the numbers help you figure out who had more beads altogether?”

The purpose of this activity is for students to choose from activities that offer practice with number and shape concepts. Students choose from five centers introduced in previous units. Students can choose to work at any previously introduced stage of these centers:

• Fewer, Same, More
• Math Fingers
• Tower Build
• Math Stories
• Which One?

Students will continue to choose from these centers in upcoming lessons. Keep the materials from each center organized to use each day.

• “¿Qué pueden hacer para trabajar con éxito en los centros? ¿Qué puede hacer su compañero para ayudarlos a trabajar con éxito? ¿Qué puede hacer su profesor?” // “What can you do to be successful when working in centers? What can your partner do to help you be successful? What can your teacher do?”
