B-I-N-G-O. A great game for both fun ... and to assist with the memorization of instructional topics like the 50 states, countries of the world, nouns, verbs, chemical symbols of the Periodic Table, Presidents, foreign language, etc. The file contains two 25 space Bingo cards (with 2 free spaces, so 48 total available spaces) that the students can complete with any of the aforementioned items plus countless others. When completed, the caller simply needs to call a related topic in which the students can mark with Bingo chips, two-color counters, candy, or pencil. For example, the caller calls Oxygen and the students mark O (or O2 depending upon your level of instruction). I typically play with basic Bingos like horizontal, vertical, and diagonal; however, you may include any others that you desire like four corners, postage stamp, full card, etc.
