This is just another way to get student's involved in the material they have just covered.
First print the BINGO sheets on regular ditto paper – one for each student in your class(es). Then print the cards on cardstock and laminate them (to keep them from year to year, put all cards between years in a zip-lock bag). Shuffle the cards and get ready to call words when student sheets are ready.
Have student's go thru and pick out words they think you might call out and write the words in ink in each of the spaces on the game sheet. Once they finish, go around a check the sheets then initial each sheet "as ready to play". When ALL sheets are ready to play, start calling out words from the cards. (Make sure you initial ANY scratch-outs or changes before the game begins). Have students X the called words with a colored pencil or marker.
Continue to call words still someone shouts "BINGO". Check their sheet to see if it is correct. Then assign them the appropriate extra credit. At that point, continue to call out words until all the extra points are given or time runs out.
This game is based on the middle school textbook – A History of the United States by McGraw-Hill and the chapter of "A More Perfect Union Era".
