The purpose of this activity is for students to think about and discuss statements that address their understanding of important ideas about fractions. Students will consider ideas about how fractions are defined, comparing fractions, and how fractions relate to whole numbers. It is not necessary for each group to discuss all of the statements, but if there are any you’d like to make sure each group discusses, let them know at the start of the activity.

Students construct viable arguments to explain their choices (MP3). In order to do so, they need to use key fraction language, such as “whole” and “equal-size piece,” precisely (MP6).

• “¿Hubo alguna afirmación sobre la que hayan cambiado de opinión durante la discusión en grupo? ¿Cuál fue la afirmación? ¿Qué los hizo cambiar de opinión?” // “Was there a statement that you changed your mind about during your group's discussion? What was the statement? What made you change your mind?”
• Consider asking:
  • “¿Sobre cuáles afirmaciones tienen preguntas todavía?” // “What statements do you still have questions about?”
