This is a great game for anything -- especially review. Here are two different cards (poster board size). Because I don't like to promote competition in Primary, I use only one card and we all work together to get a "Singo!" I have
just the numbers on the card on small pieces of paper which the children take turns drawing. We then cover the number with a big circle cut and laminated. If you use both cards, you need all the numbers from both cards and two different colors of circles to cover the numbers -- blue for one card and red for the other card. We have to sing a song or verse of a song before we draw a number. If they remember all the words they can draw two numbers. This game can take up to 30 minutes to play. It is perfect if you can use all of sharing time. It can go faster if you draw more numbers at a time.
I simply used a ruler to draw the lines then I drew the letters and numbers. You can decorate with die cuts or large stickers. I laminated both posters, 50 circles - 25 of each color, and the small numbers that the children draw from a hat, basket or sack. My boards have lasted for over 20 years! It is well worth the time and money.
You can also use this game to teach a new song. Sing a phrase 3 times then choose 3 numbers.
Sing the next phrase and draw 3 more numbers. If the children know all the Articles of Faith songs, you can draw one number every time they sing an Article of Faith. There are 13 of them and it's fun to see if they can get a "Singo" in 13 draws.
