This is part of the ABCYA website - a free Spanish game to help learn vocabulary. Click start, and choose your vocabulary category. Then choose English to Spanish, or Spanish to English. Spanish to English is easier, English to Spanish is harder.
You choose the word categories, the board size, English to Spanish (harder) or Spanish to English (easier), and when you start the game, click the box at the upper right corner of your bingo board to display the word being called. The word will appear at the bottom of your bingo board.
This website has 4 free Spanish games (colors, numbers, body parts and household objects), free videos, songs, worksheets and picture dictionaries. Instructions are also given in English. (Not all items are free, but there are quite a few free items.)
