4 X 4 Square Arrays.

NCTM Student Math Notes, Jan 1984

Several math activities designed to teach patterns which can be found in arrays of 16 squares organized into a four-by-four pattern are presented in this issue of "Student Math Notes." The activities include: (1) determining how many squares and rectangles are contained in a four-by-four array; (2) figuring out the least number of lines which can be removed from the array so that it contains no squares; (3) finding the shortest distance from one corner of the array to the other; (4) dividing the array into congruent halves; and (5) forming words out of letters which have been placed in each of the 16 squares of the array. Some activities based on a three-by-three array are also included. (DC)
