Draw a target (with points - like a dart board) on the white board or use a cardboard box in the middle of the room. Then, students make paper airplanes and launch them after they answer your question in the form of a sentence. I don't except my beginners/low intermediate students to form complete sentence so I help them to form correct sentences. To my surprise they will repeat the sentence several times (while I'm helping them) just so they can throw their airplane. For beginner and low intermediate classes, I recommend formulating questions that lead to 1 or 2 types of answers. This allows for better memorization. For example, use CAN/WILL questions and write the beginning part of the answer on the board "I can/will...". I recommend giving a prize to make the target points mean something, thus peaking their interest
