This word problem task involves ratios.
The purpose of this task is to present students with a situation where it is natural to add fraction with unlike denominators; it can be used for either assessment or instructional purposes.
This task is closely related to very important material about similarity and ratios in geometry.
The purpose of this task is to present students with a context where they need to explain why two simple fractions are equivalent.
This purpose of this task is to help students understand the absolute value of a number as its distance from 0 on the number line. The context is not realistic, nor is meant to be; it is a thought experiment to help students focus on the relative position of numbers on the number line.
Students explore the inhalation/exhalation process that occurs in the lungs during respiration. Using everyday materials, each student team creates a model pair of lungs.
Students build model sets of lungs.

Students journal their thoughts and responses to the questions associated with the grand challenge question presented in the associated lesson. For the Generate Ideas" step, they answer the questions: "What are your initial ideas about how this challenge can be answered? What background knowledge is needed? Have you tried this before?" After students have individually written responses to these questions, the class brainstorms together to reach consensus on the main ideas that need to be explored to solve the challenge question.
