This simple to use Powerpoint can be used to review or have a board race game for using Ser or Estar. 60+ slides show a sentence that students can write the answer on a smart board, white board, or chalk board. Divide class into 2-3 teams. Two or three students come up to the chalkboard or smart board and you advance the slide. The first student who writes the correct answer gets a point for his or her team. (The subsequent slide reveals the answer).
