Make sure you look at Croy section 202, where he provides the aorist forms for δίδωμι. As Croy explains, the aorist past tense indicative is formed regularly from the third principal part, which is unusual because of the kappa in the stem instead of the sigma that you would expect:
aorist past active ἔδωκα, ἔδωκας, ἔδωκε, ἐδώκαμεν, ἐδώκατε, ἔδωκαν
aorist past middle ἔδωκάμην, ἔδώκω, ἐδώκατο, ἐδωκάμεθα, ἐδώκασθε, ἐδώκαντο
What is odd about this verb is that all the other forms of the aorist system (aorist infinitives, participles, subjunctive and imperative) use a simple second aorist stem without the kappa. In effect, the stem consists of the letter δ- . For example, the aorist active participle is δούς, δοῦσα, δόν and the aorist active infinitive is δοῦναι. Croy provides some other examples that you should note in this section - make sure you take a look at them so that you will be able to recognize these forms.
You can tell immediately that you are dealing with aorist forms because they are built on the simple δ- stem, rather than the reduplicated διδ- stem of the present system (and since the perfect system is built on a different reduplicated stem, δεδ- , you can quickly recognize the perfect forms as well).
