fraction manipulatives from Doug Sundseth (downloadable)

We also played a flash card game that gave every child an equal number of questions, and involved team competition rather than individual only. “Flash Card Football” Draw a simple line drawing of a horizontal football field with end zones and goal posts on the board. Adjust the number of lines to suit your class (3-5 on each half is a good number). Place a paper cutout of a football with rolled tape on the back on the center line. Divide the class into two UNEVEN teams. Have them stand in two lines along the sides of the room. Have one pair at a time (1 from each team) come to the front of the room and attempt to answer a flash card question. The winning child gets to move the football 1 line towards his/her team’s end zone. When one team scores a touchdown, record it and start again at center. The teams are uneven so that the same children aren’t against each other every time. You can even make up team names to put in the end zones. We loved this game—boys and girls alike. You can bet it’s one of the few times we cheering aloud for division facts! Andy JoyH
