English classes for children/teen in summer

Hi
I am struggling to find English lessons for beginners, for my children aged 12 & 14, during this summer. Their first language is French but will start school in September here. I would like them to learn at least some basics. All suggestions are welcome...
Thanks

Hi,

I am a primary school teacher and have experience teaching children whose 1st language isn't english. I am in the St. Neots area, where are you?
