|Quincy Brown, a Post Baccalaureate PhD candidate in Computer Science at Drexel University, shares these Flash Activities that she developed with Annie Fetter, Math Forum staffer, and tested in a second grade classroom in Philadelphia. The five levels of Number Grid activities display a section of a matrix containing a set of of consecutive whole numbers. A move from one number to the next within a row is a change of one; a move from one number to the next within a column is a change of ten. The three levels of Number Triangle activities are an electronic version of flash cards emphasizing fact families. An addition/subtraction Number Triangle has two addends and a sum; a multiplication/division Number Triangle has two factors and a product. As children practice their basic facts, they are also learning more about inverse relationships.|
