Gait analysis is the study of human motion that can be utilized as biometric information or identification, for medical diagnostics or for comparative biomechanics. In this activity, students observe walking human subjects and then discuss parameters that could be used to characterize walking gaits. They use accelerometers to collect and graph acceleration vs. time data that can help in gait analysis—all part of practicing the engineering data analysis process. Students complete this activity before learning the material presented in the associated lesson.

The goal of this task is to get students to focus on the shape of the graph of the equation y=ex and how this changes depending on the sign of the exponent and on whether the exponential is in the numerator or denominator. It is also intended to develop familiarity, in the case of f and k, with the functions which are used in logistic growth models, further examined in ``Logistic Growth Model, Explicit Case'' and ``Logistic Growth Model, Abstract Verson.''

The goal of this task is to work on finding multiples of some whole numbers.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

Teachers skilled in classroom management are able to respond appropriately to just about any behavior that a student brings through the classroom door. While having a toolkit of specific behavioral strategies is important, the real secret of educators who maintain smoothly running classrooms with minimal behavioral disruptions is that they are able to view problem student behaviors through the lens of these seven 'big ideas' in behavior management.

In this lesson, students create Picasso-inspired self-portraits as they explore the concept of identity.

After doing facial feature sketches and a portrait shading practice, the students created their own self portraits. They were asked to create one realistic side in black and white, and one side including symbols about their identity which was completed in color.

Students are to fill in a silhouette portrait of their bust using a color scheme, doodles and symbols.
