Addressing the direction of high school mathematics in
the 21st century, this resource builds on the ideas of NCTM’s Principles and
Standards for School Mathematics and focuses on how high school mathematics can
better prepare students for future
success.

Reasoning and sense making are at the heart of the high
school curriculum. Discover the components of mathematical reasoning and sense
making in grades 9–12,
including:

* Reasoning habits that instruction should develop across the curriculum

* Key elements for reasoning in five content strands

* Examples that
illustrate the roles of teachers and students in the classroom

Focus in High School Mathematics aims to bring together teachers,
administrators, supervisors, and curriculum specialists to reshape the
conversation about high school mathematics and shift the curriculum toward an
emphasis on reasoning and sense making for all students.
