How would I say the following in Japanese?

Question:

So.. it seems my grammar is really bad and I can't understand why. Could you please help me and translate into Japanese the following?

"I went home to talk about a project."

"Would it be alright if we talked about food?"

"I rode my bike to the store to buy candy."

Thank you for your help!

Answer:

Hi, the followings are the translations.
Because I'm not sure the context, I translated literally.

"I went home to talk about a project."
プロジェクトについて話し合うため家に帰りました。
project ni tsuite hanashiau tame, ie ni kaeri mashita.

"Would it be alright if we talked about food?"
食べ物について話し合っても良いですか？
tabemono ni tsuite hanashi attemo, yoidesuka?

"I rode my bike to the store to buy candy."
キャンディーを買うために自転車で店へ行きました。
candy wo kautame ni, jitensya de mise e ikimashita.
