Mathematical Practices

This page is a resource bank to keep focused on the mathematical practices. Beginning with rich math tasks, my hope is to ground classes in tasks that engage students with mathematics. I also begin classes with a variety of openers to immediately capture the attention of students and have them “dive” into math.

First – read Fawn Nguyen’s posts on problem solving. Read it again and return to periodically!

Working on the Practices

Class Opening Cycle based upon the day. My school is currently on a six-day cycle and I see my students for math every other day. My current opening practice depends on the day of the week and generally follows the schedule below. As such, over a two-week period, students typically get one of each opener. (Note: the Day E is part of the rotation. On this day, I will provide students with a problem to do over the week. Each “Day E” a problem is due and a problem is started.)

    1. Monday- Graphing Story / Graph of the week
    2. Tuesday- visual patterns 
    3. Wednesday- Estimation 180
    4. Thursday- mental math / math talk / dot problems 
      1. Lots of dot patterns here
    5. Friday- reflection in relation to math practices
    6. Day E – Problem of the Cycle
