Yes, the days of the week only have one form for both singular and plural (except for sábado and domingo). You don't need to add -es, so:
Los lunes juego al baloncesto. (On Mondays I play basketball) - plural
Cada lunes juego al baloncesto. ( Each Monday I play basketball) - singular
Hola Ronald - if you look the -ES ending of the "wrong example" is crossed out. I'll add "this is wrong" before it just to make extra sure students realise we are giving a wrong example here.
Thanks Shui, Saludos Ron
