It's quite easy to get the similar-looking werden, wurden and würden confused, so we're taking a look today at the differences between them and the different contexts in which they are used.
To start with, wurden and würden are different grammatical moods of the verb werden.
Heute in unserer ersten Lektion werden wir die Buchstaben des deutschen Alphabets lernen.

As you can see, werden can be used in a wide variety of contexts and can be translated variously as "will," "get," "will turn into," and "become." The last example uses the future tense of the verb, wird werden, which is translated as "going to be."
In contrast, wurden is the Indikativ mood (similar to the indicative or realis mood in English) of werden. This just means that the verb is used to express a known state of affairs.
Sie flohen aus dem Königreich und wurden nie wieder gesehen.
They fled from the kingdom and were never seen again.

Here, wurden gesehen is the passive voice of the German Präteritum, as is common with the combination of werden and a past participle.
Wahrscheinlich wurden sie im hohen Norden auf dem Eis für die Jagd verwendet.
They were probably used for hunting on the ice in the far north.

Thus, wurden is usually translated as "were," but it is also sometimes used in the same sense that the present tense werden is sometimes translated as "become." The sentence Aus Bauern wurden Arbeiter could be translated as "Farmers became workers," which has a very different verb structure but a similar meaning in the end.
Ähm, was würden Sie denn als ihre Stärken und Schwächen, ähm, beschreiben?
Um, what would you then, um, describe as your strengths and weaknesses?

In colloquial German, it is common to hear the word grad, which is slang for the adverb/adjective gerade and could easily be confused with the noun Grad. The adverb gerade can be translated as "just," "especially," "exactly," "just now," or even as "directly." The adjective gerade is usually used to describe "even," as in even and odd numbers, and is translated as "level," "direct," "upright," and "ingenuous" as well.
Wir sind ja grad [gerade] erst gekommen.
We indeed only just arrived.

However, the neuter noun das Grad is a technical term that refers to measurable "degrees" of temperature or the "degree" of a geometric angle. In non-technical usage, it is a masculine noun (der Grad) and may refer an academic degree.
Es soll bis über zwanzig Grad warm werden.
It should get warm, up to more than twenty degrees.
