Algebra Card Sort is a way for students to develop their understanding of the relationships between different representations of math ideas. Students match cards of different types of representation with the same concepts such as a table that coincides with a graph.
The initial version of the app includes two different card sorts. First, combining equations and word problems with integers. Second, combining tables, graphs, equations, and word problems involving distance and time. The second card sort is based on the work of the Mathematics Assessment Project at the University of Nottingham (http://map.mathshell.org/). If you have a set of cards that might be appropriate for the app and focus on an area of algebraic thinking, please contact us! We will try to include it in the next version.
