Sitting in groups, listening to the explanation of your friend, let's play the "Finding Your Seat' game.

For example, there are 6 students at the table. If the leader says,"Tom is between Bill and Sam.", they should change their seats. If Tom is sitting on another chair, he should stand up and go to the chair between Bill and Sam. The student who is sitting between Bill and Sam should move to another seat. The leader should use the following expressions:next to, across from, and between. By doing this activity, you should know how to use the three expressions. When you listen to the explanation of the leader, you should move quickly.

You're doing really well in your English studies. All of us here have noticed that! Keep up your hard work!

The explanation you provided is mostly correct, but there are a few minor adjustments that can be made to improve clarity.

"In the 'Finding Your Seat' game, students sit in groups and listen to their friend's explanation. The leader then gives instructions using expressions such as 'next to,' 'across from,' and 'between.' For example, if the leader says, 'Tom is between Bill and Sam,' the students should change their seats accordingly. If Tom is sitting in a different chair, he should stand up and move to the seat between Bill and Sam. The student who was previously sitting between Bill and Sam should then move to another seat. The goal of the game is to quickly understand the leader's instructions and move to the correct seat. By playing this game, you can practice using these three expressions effectively."

I hope this revised explanation helps you. Keep up the great work in becoming a better English speaker and writer!
