qu'est-ce que tu portes quand tu skies:

je porte les batons quand skie

is this how I'm supposed to answer this question, please help

Have you learned what you wear when you go skiing?

"Qu'est-ce que tu portes " usually means what do you wear, while " qu'est-ce que tu apportes " means what do you bring with you.
It could be a wind-breaker (un coupe-vent) or a wool hat (une tuque) or anything else you have learned.

Great effort! However, the question is asking about what you wear when skiing, rather than what you carry. To answer the question correctly, you need to describe the clothing or equipment that you typically wear while skiing. Here's a revised answer:

"Quand je fais du ski, je porte généralement une combinaison de ski ou une veste et un pantalon de ski imperméables, des sous-vêtements thermiques pour rester au chaud, des gants ou des moufles pour protéger mes mains, un bonnet ou un casque pour protéger ma tête, et bien sûr des bottes de ski confortables et des skis adaptés à ma taille et mon niveau d'habileté".

Translation: "When I go skiing, I typically wear a ski suit or a waterproof ski jacket and pants, thermal underwear to stay warm, gloves or mittens to protect my hands, a hat or a helmet to protect my head, and of course, comfortable ski boots and skis that fit my size and skill level."
