TeachingWorks has gathered and made publicly available records of practice related to the Elementary Mathematics Laboratory through the Teaching & Learning Exploratory.

The Grand Rapids Elementary Mathematics Laboratory (GREML) 2012 Collection documents a summer mathematics laboratory class taught by Deborah Loewenberg Ball, an experienced elementary school teacher and director of TeachingWorks at the University of Michigan School of Education. GREML2012 was a one-week summer mathematics laboratory designed to develop strong and positive academic identities in students and to contribute to the professional growth of teachers who observed the lab class sessions. Mathematics topics included fractions, the number line, equivalence, and place value, along with important mathematical practices, such as explaining, representing, proving, and defining. The collection includes video of the daily class sessions as well as video of the pre-brief and de-brief sessions between Dr. Ball and the adult EML participants. Additionally, over 173 lesson artifacts including lesson plans, lesson materials, class handouts, seating charts, digital scans of handwritten student notebooks, homework papers, study guides, and test papers are included in the collection.

Collections of videos and materials from the 2014 and 2015 EML sessions are scheduled to be released on the Teaching & Learning Exploratory (TLE) in January of 2016. For more information or to subscribe to the TLE and access these videos, click here.
