 Activity for teaching English summer camp, water balloon toss. You only need to throw the term water balloons into the classroom, and your student's eyes will twinkle in excitement. While it's already incredibly fun to simply throw water balloons around the room, the activity has to involve English. To do this, set up two small blackboards and prepare several markers. Next, fill the water balloons and split your class into two teams. To play the game the teacher yells out a word, and two students from each team run to the blackboards and write the word on it. The first student to be done yells finished. And if the word was spelled correctly, they can throw a water balloon at the other student. You can also add more rules, for example the target isn't allowed to move, but if they do, the thrower gets a second chance to throw or something to that effect. At the end, you can also do a KO match between the best players of each team. The winning team then gets to throw all the remaining balloons at the losing team.
