Here is a really good speaking game I found on a previous textbook's thread:Make cards with the number one on them. Give each student 5 cards each to start with. In pairs the children say "hello," then ask each other, "how old are you?" One card represents one year, so if you have 5 cards, you are 5 years old etc.. Then the kids do rock, paper, scissors, the loser gives the winner one card. At the end of the game the oldest person is the winner.
a very very simple intro i will do, i usually do it a few times and tell stories inbtwn with examples and ask the kids questions based on it, i don't just slide by it. but i hope it's ok for u to use.also a mario game edited for this lessonas well as a pass the ball game (my kids love this game)
