Our ideas for the development of Quick Blocks draw heavily from Wheatley’s Quick Draw (2007) and number sense ideas found in Wheatley and Reynolds’ Coming to Know Number (2010). Quick Blocks was built on the basis of three other classroom routines: Quick Draw, Quick Images, and Quick Build. You can read and watch more about the importance of spatial sense and the use of Quick Blocks in the classroom in NCTM's Mathematics Teacher:Teaching and Learning journal.
