The purpose of this activity is for students to learn Stage 2 of the Sort and Display center. Students work together to sort 20–30 objects into three or four categories. They each make a picture or bar graph that shows how they sorted. Then they take turns asking their partner 2 questions that can be answered based on their graph. Students are given an opportunity to sort items, represent how they are sorted, and create questions that can be asked about the data in their representation (MP2, MP6).

To connect this center to English Language Arts, students could use books to find a collection. Students look at the cover of a book and choose three to four words or images they think will show up most often in the story and explain why to their partner. Partners record these choices as initial categories. Students then read or look through the book together, explore their prediction and decide together if they want to revise their categories based on what they’ve read. On the second read, they collect and record data for their revised categories. Lastly, students create representations based on their data and write 2 “how many?” questions that can be asked about the data in their representations.

• Display student representation.
• “¿Qué preguntas podemos hacer acerca de la representación que muestra cómo se clasificó la colección?” // “What questions can we ask about the representation of how the collection is sorted?”

The purpose of this activity is for students to choose from activities that focus on adding or subtracting.

Students choose from previously introduced stages of these centers:

• What's Behind My Back?
• How Close?
• Number Puzzles

• “¿Qué actividad escogieron? ¿Qué les gustó de la actividad que escogieron?” // “Which activity did you choose? What did you like about the activity you chose?”
