High School Geometry
The Standards Mastery Document is designed for educators by educators as a resource and tool
to help educators increase their depth of understanding of the Common Core Standards. This
document will enable teachers to plan College & Career Ready curriculum and classroom
instruction that promotes inquiry and higher levels of cognitive demand.
The Standards for Mathematical Practice describe varieties of expertise that mathematics
educators at all levels should seek to develop in their students. These practices rest on
important “processes and proficiencies” with longstanding importance in mathematics
education.
8 Mathematical Practices (MP):
MP 1. Make sense of problems and persevere in solving them.
MP 2. Reason abstractly and quantitatively.
MP 3. Construct viable arguments and critique the reasoning of others.
MP 4. Model with mathematics.
MP 5. Use appropriate tools strategically.
MP 6. Attend to precision.
MP 7. Look for and make use of structure.
MP 8. Look for and express regularity in repeated reasoning.
