Answer:
Ich beschrieb meinen Tag.
Explanation:
Describe your day translates into "Beschreibe deinen Tag". Praeteritum tense is similar to simple past tense in English. Describe your day is not past tense, so we have to change it to past tense. "Ich beschrieb meinen Tag" translates into "I described my day". It would be helpful to see your full assignment to be a 100% correct here. Depending on your assignment, you might have to change it to "you described your day" aka "Du beschriebst deinen Tag".
