This Session

• Free tools like Geogebra and Desmos empower mathematics teachers to create engaging lessons for students.

• Explore the thought processes behind constructing engaging lessons that spark students’ curiosity and reconcile algebraic, geometric, tabular, and graphical representations.

• Problems/resources will be provided.

• Participants should bring their best ideas with them to share with others.

• Participants are encouraged to bring technology (laptop or tablet) but this is not required.

We need to establish a community of practice.

We are preparing our students to solve problems that do not yet exist.

Is it the responsibility of the math teacher to prove the relevancy of school mathematics?

Or is it the student’s job to find opportunities to use mathematics as vocabulary to describe the world?

Either way:The teacher sets the task.
