One of my favorite games to play with my Basic Skills classes was "Guess My Number". I would hand out paper, tell them to number it 1-10 and then we would begin. With younger students I would tell them to write three blank lines in the first space. Then I would start to ham it up. I would tell them I was thinking as hard as I could of a number and we would see if they could read my mind. After lots of head holding I would start to announce, in a trance-like voice, a number and its position. For example...a one in the tens place, a three in the ones place, a two in the hundreds. They would place each number in the blank space. Then I would ask who could guess my number. Corny, yes. Effective-always.
I would use this with older students into the billions. First I would explain that each common represented a word. Once they understood that they really only needed to say a three-digit number followed by the correct word (comma), they would get into the game as well. I think I always enjoyed it the most when a student was willing to take over and lead the game. I felt then I had really reached them.
Here are a few task card collections that I developed to use with my students.
