A problem with 5 solutions!!

A problem with 5 solutions!! (A real story)
I was going to teach a chess class at a primary school and I was concerned that my students in their games did not use the resource of sacrificing pieces to obtain victory, a fact that occurred on several occasions...
On the way to school I mentally put together this problem with the intention that once and for all they learn to sacrifice!!
I was proud to do it mentally... how good!!

the solution is easy! 1. Kh8+, Kxh8 and Kf8++
I arrived at school and started the class continuing with the internal tournament of the course, but a student (of the restless ones) was left free without a partner with whom he could play, so while his classmates were playing I got ready for him to solve the problem and in that way form was going to keep him pretty busy, because I was sure Rh8+ wouldn't find it for quite some time.
At 15 seconds...
Student: I already solved it!
I got closer and saw that he played 1. Kh6!, Kh8 and Kf8++
(grrr, I didn't see that one! I thought) and I told the student that it was fine but that wasn't the solution, that there was another one, and I left
After 10 seconds the student answers me, that's it!
I go to see the solution and see that it plays 1.Kf6, Kf8 and Kh8++
(grrr, again!) and I let him again that there was one more solution, and that he try to think about it because it was difficult, and I dedicated myself to the tournament
at 20 seconds...
Student: I already found it!
I approach the board and to my amazement I see that he played: 1.Khg1, Kh8 and 2. Kf8++.
At this point my pride had already fallen well to the bottom
Again I told him that it was very good but that there was more
And I leave it to you to solve the fifth solution that the student found. Which?
Even though the kid didn't find 1.Kh8+, he found 4 other solutions, so I ended up beaten 4-1.
Moral: "Never underestimate your rival and less yourself"
