The game board can be any size as long as it is square (3X3, 4X4, etc.). If you are teaching elementary school children the alphabet, use a 5 x 5 grid, which allows the children to fill in almost every letter of the alphabet. Students are given the bingo grid and a bunch of words that they are supposed to fill the Bingo grid with have more words than spaces once they have finished, start calling out words or sentences that contain the words. Can also be played with vocabulary words. Call out words and the students write them on the bingo grid wherever they like. Then call out the vocabulary words one by one until someone gets bingo. Vary the ways to win. Sometimes make it one row, sometimes make it two rows or a special design (e.g. T or X ).
