chess board editor

hello everyone
i am primary school teacher and i have started a chess class but i need a software to make lessons i mean kind of chess board editor
any one who can help
and if you wanna donate contact me
thanks

there's an analysis board in the "Tools" section at the top and a board editor for setting up positions to go with it. If you want a downloaded application I use Scid with Stockfish 8 but I don't know if you can make arrows with that.
