I'd perhaps say "Nihongo wo oshiete kuremasen ka?"　(日本語を教えてくれませんか)

If I do word for word translation, I say "日本語を学ぶためにお手伝い頂けますか？" But I think this way isn't common and I can't come up with any sentences to express that in Japanese. (If I must say, that is ”私の日本語学習にお手を貸して頂けませんか？" But I feel like that is awkward) Sara's answer－日本語を教えてくれませんか is natural and usuful.

im learning japanese aswell good fun
