Gå frem til tavlen og skriv datoen.

Because this is an imperative sentence, meaning a command or instruction. In Danish, as in English, the subject is usually left out in commands.

• Gå frem til tavlen = Go up to the board
• Skriv datoen = Write the date

The implied subject is you.

Gå is the imperative form of the verb at gå (to go / to walk).

Common forms are:

• at gå = to go
• jeg går = I go / I am going
• gå! = go!

In commands, Danish often uses the bare imperative form like this.

Til means to, but frem til adds the idea of moving forward / up toward something.

So:

• gå til tavlen = go to the board
• gå frem til tavlen = go up to the board / come forward to the board

In a classroom context, frem til sounds very natural because the student is moving up to the front.

Tavle means board, and tavlen means the board.

Danish usually adds the definite article to the end of the noun:

• en tavle = a board
• tavlen = the board

So the -en is the Danish way of saying the.

Because skriv is the imperative form of at skrive (to write).

Compare:

• at skrive = to write
• jeg skriver = I write / I am writing
• skriv! = write!

In commands, Danish uses the imperative, just like English uses write!

Og means and. It connects the two commands:

• Gå frem til tavlen
• og skriv datoen

So the sentence gives two actions in sequence:

1. Go up to the board
2. Write the date

Datoen means the date, while dato means date in a more general sense.

Here, the speaker means a specific date that should be written down, so Danish uses the definite form:

• en dato = a date
• datoen = the date

This is similar to English, where a teacher would usually say write the date, not just write date.

Not necessarily. In Danish, the imperative is very commonly used for instructions, especially in places like classrooms, workplaces, recipes, manuals, and signs.

So Gå frem til tavlen og skriv datoen is direct, but in the right context it sounds normal, not impolite.

Tone of voice matters a lot, just as in English.

The sentence has very straightforward command structure:

• Gå = verb
• frem til tavlen = direction/place
• og = and
• skriv = second verb
• datoen = object

So it is basically:

Verb + place + and + verb + object

This is very common in Danish instructions.

A rough pronunciation guide is:

Gå frem til tavlen og skriv datoen
goh frem til TAWL-en aw skreew day-to-en

A few notes:

• gå has a long vowel, something like goh
• tavlen is roughly TAWL-en
• skriv sounds close to skreew
• og is often pronounced more like å in normal speech than a very clear og

Pronunciation varies a bit depending on speaker and region, but that approximation is enough to get started.

Yes. Tavle can refer to a classroom board in general, so in modern usage it may mean either a blackboard or a whiteboard, depending on the context.

In a classroom sentence like this, tavlen is best understood as the board.
