Choose German accusative or dative by checking the verb or preposition that governs the noun phrase. Direct objects often take accusative, while verbs such as helfen require dative. With two-way spatial prepositions, a destination takes accusative and a location takes dative. Movement alone is not the rule: someone can run inside a room and still use dative.

“Accusative means movement, dative means no movement” is memorable and wrong. It fails as soon as you say that you are running in a park. The reliable question is what relationship the verb or preposition expresses.
Three decisions that look similar
Construction
Example
Reason for the case
Verb takes an accusative object
Ich sehe den Hund. — I see the dog.
Sehen requires this direct object in accusative.
Verb takes a dative object
Ich helfe dem Kind. — I help the child.
Helfen requires dative.
Fixed-case preposition
mit dem Hund / für den Hund
Mit takes dative; für takes accusative.
Two-way spatial preposition
in den Park / im Park
Into the park is a destination; in the park is a location.
When you give something to someone
Ich gebe dem Kind den Ball. — I give the child the ball. With geben, the recipient is dative and the thing given is accusative. Das Kind becomes dem Kind; der Ball becomes den Ball.
This is useful for common giving, showing and telling constructions. Do not expand it into “every person is dative and every object is accusative”. Ich sehe den Mann has an accusative person; Ich helfe dem Mann has a dative person. The verb decides.
Location and destination, not motion and stillness
Compare Ich gehe in den Park — I’m going into the park — with Ich laufe im Park — I’m running in the park. In the first, the park is the destination. In the second, the running happens within that location. Im is in dem.
The same contrast works with objects: Ich lege das Buch auf den Tisch — I put the book onto the table — and Das Buch liegt auf dem Tisch — The book is on the table. Auf is a two-way preposition, one that can take different cases for these spatial meanings.
Do not apply the spatial rule to every preposition
Zu takes dative even for a destination: Ich gehe zum Bahnhof — I’m going to the station. Zum combines zu dem. A person is plainly moving, but the preposition still takes dative.
Some verb–preposition combinations are not literal spatial descriptions: warten auf + accusative means wait for. Learn the combination as a phrase. The image of “moving onto” something will not help with Ich warte auf den Bus.
Check the form after choosing the case
For masculine nouns, nominative der becomes accusative den or dative dem. Feminine accusative remains die, but dative becomes der. Neuter accusative remains das, but dative becomes dem. You need the noun’s gender as well as its role.
Choose: Ich tanze in ___ Küche, meaning I dance in the kitchen. Answer: der, feminine dative for location. Now Ich gehe in ___ Küche, meaning I enter the kitchen. Answer: die, feminine accusative for destination. Same kitchen, different relationship.
