Middle School Mathematics

St. Clare Mathematics Curriculum reflects the Common Core State Standards and Mathematical Practices

We emphasize mathematical practices as we approach each area of content.

St. Clare’s advanced math course of study compacts four years of math into three by increasing the pace of instruction and allowing students to leave middle school having covered math content through Algebra 1.   Multiple pieces of evidence including  previous teacher recommendations and a placement test given at the beginning of 6th grade help determine the proper course of study for each student. Students planning to attend Catholic high schools will be well prepared for the Algebra 1 Challenge Exam given by the high schools in April.  Scoring well on this exam will allow them to begin high school in Geometry.

Mathematical Practices

  1. Make sense of problems and persevere in solving them.
  2. Reason abstractly and quantitatively.
  3. Construct viable arguments and critique the reasoning of others.
  4. Model with mathematics.
  5. Use appropriate tools strategically.
  6. Attend to precision.
  7. Look for and make use of structure.
  8. Look for and express regularity in repeated reasoning.
