Question

I have to be able to identify an adjectives gender tomorrow. Could you maybe give me some exercises to practice it?

Answer 1

You're probably up through first and second declensions, right? Adjectives will match the endings on the nouns they modify.
1st decl = http://econrad.net/latin/ln1.html
2nd decl = http://econrad.net/latin/ln2.html

<b>First declension endings on adjectives -- always feminine:</b>
Singular endings ~
-a
-ae
-ae
-am
-a

Plural endings ~
-ae
-arum
-is
-as
-is

<b>Second declension endings on adjectives -- always masculine or neuter:</b>
Singular endings -- masculine, then neuter:
-us, -um
-i, -i
-o, -o
-um, -um
-o, -o

Plural endings -- masculine, then neuter:
-i, -a
-orum, -orum
-is, -is
-os, -a
-is, -is

Pulcher is a commonly used early adjective.

NOMINATIVE (used for subjects and predicate nominatives or pred. adjectives)
A pretty girl = puella pulchra
The pretty girls = puellae pulchrae

ACCUSATIVE (used for direct objects and some objects of prepositions)
He saw the Roman houses. = Casas Romanas videt. (Romanus is the adjective here, modifying casas, the direct object.)
