I have a child in my class (Y4) who has recently arrived in this country, he speaks Portuguese, but I have begun to suspect he has had no previous education at all, he cannot read Portuguese and he doesn't understand maths symbols such as + or - . I have him on Maths plus, but my problem is teaching English, has anyone ever had an experience like this? Luckily, there is a child in Year 3 who is bilingual and I have often used her expertise in translating. He is beginning to understand more of spoken language, I had thought about just matching cards to words and building on that, in a similar way to duolingo. I would welcome any advice.
