Why Mathematics at Work™?
Mathematics at Work is built on the fundamental belief that every K–12 student can learn mathematics. Participants in the Mathematics at Work professional development:
- Gain deeper insight into the essential mathematics team agreements as part of the Professional Learning Communities at Work™ process.
- Reflect on current practice using team-discussion protocols, author stories, teacher-reflection activities, and team recommendations for their daily work.
- Examine research and professional best-practice design criteria for unit assessments, daily instruction, daily homework, grading, and schoolwide mathematics intervention.
- Examine research and professional best-practice design routines for unit assessments, daily instruction, daily homework, unit grading, and subsequent schoolwide mathematics intervention.
The authors of Mathematics at Work understand that to achieve this purpose, teachers and leaders of mathematics should establish a reflect, refine, and act formative learning process for their students and for themselves. Mathematics lesson design and implementation, assessment design and intervention, and homework design and grading routines become purposeful outcomes to support your school or district—one teacher, teacher team, and teacher leader at a time.
Perseverance and ownership
Use mathematics assessment, lesson, and homework design criteria to help your students develop confidence, ownership, and productive perseverance in their daily mathematics learning.
Reflective and routine
Establish highly effective mathematics instruction, assessment, intervention, and grading routines to help your students become active participants in a formative feedback cycle of learning.
