Just about all of the Rangers will head to much warmer climes when the club’s bye period begins following Tuesday’s Garden showdown/throwdown against the Islanders in a match of some fair early-winter significance.

But not Kaapo Kakko.

He will be en route to someplace better.

Home.

To Finland.

“It will be so good for me,” the 18-year-old freshman told The Post following Monday’s practice. “I have the chance to be with my family and my friends. It has been some time.”

Kakko has not been home since the summer. He has not seen his parents since they traveled here for the season opener and their son’s NHL debut.

“I FaceTime with my family and friends, but it will be good to be home,” Kakko said. “It will be good to get [this break] and then come back and be better.”

Kakko’s season has not gone quite as planned. The winger has scored a total of seven goals, with one in 27 games over the past two months. Overheated summer projections seem to have overlooked the fact that the second-overall draft pick was, and is, a teenager living in an adult world, and on the other side of the world.

David Quinn said “I do” faster than Sean Avery could get those words out of his mouth at his wedding ceremony with Hilary Rhoda when the coach was asked whether he thought the break is coming at the right time for Kakko.

“As we’ve all touched on, there have been a lot of challenges for him, not only hockey-wise but life-wise for 18-year-olds,” Quinn said. “He’s had his ups and downs, but he had a big smile on his face today when we talked about the break. I thought he had a really good practice.”

When the Rangers seek their third straight victory within nine days over an Islanders team whose hold on a playoff spot has become tenuous after having won just one of the past six (1-3-2) and five of the past 15 (5-7-3) games, Kakko will line up on the right side of a line with 21-year-old Brett Howden on the left and 20-year-old Filip Chytil in the middle.

The youngsters have been together for 10 games, since Quinn united them in Toronto on Dec. 28. Even if the numbers haven’t exactly dazzled (46.3 percent possession, 40.9 percent shot share, 39.5 percent xGF and two goals scored and five against in 82:52 of five-on-five time as a unit), the kids have formed a bond with each other. Sometimes, it is about small steps.

Sometimes it is about kids helping their contemporaries.

“Fil’s been a help to him, and I know Howden’s been a help to him,” Quinn said. “It can’t always come from the coaches. It has to come from the players themselves, and I think those guys have done a good job with him.”

Kakko still won’t use his age and inexperience as crutches. He still heaps immense pressure on himself and expects more from himself. Still, he recognizes that the NHL is not Liga, the Finnish league where he established himself as a top-two selection.

“I think he does [recognize that],” Quinn said. “He and I have talked. This is all new to him. He’s never been on a third line. He’s always been the top guy. He’s always been the guy who’s scored. You know, it’s taken some time for him to realize that doesn’t happen, and I always use Svechnikov as an example to him.”

That was a reference to Carolina’s Andrei Svechnikov, the Russian winger who was the 2018 second-overall selection in the draft. Svechnikov had 12 goals and 22 points in 50 games entering the Canes’ bye period as compared to Kakko’s seven goals and nine assists in 43 contests. Svechnikov finished his rookie season with 20 goals and 37 points.

“It was really in the last two months when he kind of turned the page and became the player that he is today,” Quinn said “The more you tell a guy that, I think they start believing it, but I don’t think they believe it out of the gate.”

So one more game before the break. One more game for Kakko before he gets to taste some home cooking. One more game for the Rangers, who dropped Sunday’s to the Jackets in brutal fashion, allowing the 2-1 losing goal at 19:35 of the third period on a three-on-two rush that began below the Columbus goal line.

“We can’t let last night get in the way of tomorrow night,” Quinn said Monday. “We can’t let the last minute of last night’s game cost us two hockey games.”
