I really need your help to express a few things related to skiing. As a matter of fact, I don't know much about it. Thank you very much for your help.

1) Do you happen to know anything about an Ipad application called Siri, which should be able to send vocal messages? (this is a real question)
2) We spent the morning finding ski boots which fit my child ( or suitable ski boots for my son). They seemed to be either too tight or too big.
3) (At the end?) We hired (him?)a pair of skis, sticks (poles), a helm as well as the ski boots (for him) for five days. We paid 50 Euros for all ski equipment. Can you say “as a whole”, “in total”, “ all together” (I don't think it is correct).
4)We also bought a one-day ticket (ski pass? How do you call it) for my child and myself.
5) We had a snack for lunch. My son had a tomato and cooked ham sandwich and a glass of still water. We had (a) cheese-and-ham toasts.
6) We also booked a one-hour ski (or ski) lesson with a ski instructor for the early afternoon as well as a five-day group course starting from tomorrow.

I don't know anything about it either, but you should find some good explanations in here: http://www.google.com/search?rlz=1C1GGGE_enUS379US379&sourceid=chrome&ie=UTF-8&q=ipad+siri

2) We spent the morning finding ski boots to fit my son. They seemed to be either too tight or too big.

3) We ended up renting him some skis, poles, a helmet, and ski boots for five days. We paid 50 Euros for all the ski equipment.
Can you say “as a whole”, “in total”, “ all together” (I don't think it is correct). <~~I'd say, "overall."

4) I also bought one-day ski passes for my child and myself.

5) We had a snack for lunch. My son had a broiled ham and tomato sandwich and a glass of water.
We had cheese-and-ham toasts.

6) We also booked a one-hour ski lesson with a ski instructor for the early afternoon, as well as a five-day group course starting tomorrow.

1) Yes, I can help you with that! Siri is actually not an iPad application, but a voice-activated virtual assistant developed by Apple. It is available on various Apple devices, including the iPad. Siri can perform various tasks, including sending vocal messages. To send a vocal message using Siri on your iPad, you can simply activate Siri by saying "Hey Siri" or pressing and holding the home button (on older iPad models) or the side button (on newer iPad models without a home button). Once Siri is activated, you can say commands such as "Send a vocal message to [contact's name]" and then dictate your message. Siri will transcribe and send your message for you.

2) It can be challenging to find the right ski boots, especially for children. To find suitable ski boots for your child, you'll want to consider their foot size, foot shape, and comfort. One way to determine the proper fit is by measuring the length and width of your child's foot and comparing it to the manufacturer's sizing chart. It's important to note that ski boots should be snug but not painfully tight. They should offer enough support and control without restricting blood circulation.

3) Based on your description, you can say: "We rented a pair of skis, ski poles, a helmet, and ski boots for him for five days. We paid 50 Euros for all the ski equipment." Alternatively, you can use phrases like "as a package," "in its entirety," or "all inclusive" instead of "as a whole," "in total," or "all together."

4) The term commonly used for a one-day ticket for skiing is a "ski pass" or a "lift pass." So you can say, "We also bought a one-day ski pass for my child and myself."

5) For the description of your lunch, you have accurately mentioned the items you and your son had. However, it's not necessary to include the word "a" before "cheese-and-ham toasts." So you can say, "We had cheese-and-ham toasts" instead of "We had a cheese-and-ham toasts."

6) Great! You have booked both a one-hour ski lesson with a ski instructor for the early afternoon and a five-day group course starting from tomorrow.
