Divide students into two teams. Write two lists of unit words on the board (one for each member of each team). Each team forms a line leading to the board. When given the signal, the first child on each team goes up to the board, points at the first word in the team’s column, and reads aloud that word. If the student reads the word correctly, he or she erases that word. The student then moves to the back of his or her team’s line. The first team to erase all the words on their list wins.
