When I was a first-year teacher, my lesson plans looked like this.
"Warmer (game)
Grammar
Game
Book p14-15
Game
Review"
Games were great at entertaining my classes. Much later I realized that some games were also great for learning English. The challenge was figuring out which games.
If you want your games to be more than a break between grammar drills and book work, check your games against “GAMES” (Group, Appropriate, Motivating, English, Skills).
