Checkmate with two rooks

 
After learning how to checkmate with a queen, my class will learn how to checkmate with 2 rooks.

I know it can be done by two moves but first i want my students to learn the technical. 

Each rook need to close another rank till the King is checkmate.

First the a or h rook goes to 2, then to 3 following up till 8.

At this stage i´m finding some students who still capture the king, wrong.

If the king captures one of the rooks, they need to restart the game.

Advanced kids will learn to do a waiting move.

Will edit and update this post during this week.
