The trap English speakers fall into
Watch out
"So that I could see the board" is a purpose in English, but 見える is not something anyone decides to do — it happens or it does not — and its subject is the board, not the speaker. Either reason rules out ために. A hoped-for state like this takes ように.

The full explanation
Read it all · about 1 min
ために after the dictionary form of a verb gives the purpose of an action: 日本で働くために、日本語を勉強しています, "I am learning Japanese in order to work in Japan". After a noun it takes の and means "for" or "for the sake of": 家族のために, 健康のために.
Purpose ために has two conditions. Both clauses have the same subject, and the verb before ために is something a person can decide to do — 買う, 行く, 勉強する. When the goal is a state you cannot simply decide on — being able to do something, understanding, seeing, not forgetting — the right word is ように (see the next topic).
After the た-form, or a noun in a news-like sentence, ため(に) gives a cause: 事故のために電車が遅れました, "the train was delayed because of an accident". This is formal and objective, the language of announcements and reports, and everyday speech says から or ので instead.
English uses "to" for purpose everywhere: "I went to the shop to buy bread". With verbs of going and coming, Japanese has a lighter pattern — the ます-stem plus に: パンを買いに行きました. ために there is not wrong but sounds weighty, as if the bread were a life goal.
A closer look
Purpose or cause?
The same word does both jobs, and the form in front of it usually decides. A dictionary form looks forward, to something not yet done: purpose. A た-form looks back, to something that has happened: cause.
After a noun, the main clause decides. 試験のために勉強する is studying for an exam — purpose, because studying is deliberate. 試験のために授業が休みになった is a class cancelled because of an exam — cause, because nobody chose the cancellation in order to achieve the exam.
Exceptions and special cases1
Exception
When the main verb is 行く, 来る or 帰る and the purpose is an ordinary errand
then the ます-stem plus に is the normal form: 買いに行く, 会いに来る.
週末、祖母に会いに行きます。I am going to see my grandmother at the weekend.
Why? ために emphasises a goal that has to be worked towards. For a trip to the shop, that emphasis is out of proportion, and the light に fits.

ための before a noun
ために drops its に and takes の when it describes a noun: 子どものための本, "a book for children"; 日本語を勉強するための本, "a book for learning Japanese". Titles, signs and packaging use this constantly.
初めて日本に来る人のためのガイドです。This is a guide for people coming to Japan for the first time.
