His friendly style has earned him the nickname 'Mr Cuddly' from his pupils - and now he is schooling the entire nation.
Ray Cuddihy (38) has become one of the most famous faces in the country for those with children of primary school age.
The teacher from Doneraile in north Cork graduated with a Masters in education from Mary Immaculate College, Limerick in 2019.
But like many, the substitute teacher saw work dry up when the country's schools closed down due to coronavirus.
When RTÉ bosses decided to schedule a teaching show to help the country's families during the pandemic, the former RTÉjr actor and puppeteer was one of their first choices.
And Mr Cuddihy went from worrying about work to being extremely busy planning class schedules for Ireland's children.
"I'm loving it, absolutely, I am," Mr Cuddihy said. "I'm learning more as I go on, to adapt the classroom for this unique situation.
"I'm getting more creative and imaginative. I love teaching and TV and I'd always dreamed the two could coexist, one informing the other.
"I worked for RTÉ for about five years, as a puppeteer on RTÉjr. I do some Irish language work for TG4 too.
"I've been involved in young people's educational theatre and in 2017 I did a Masters and used all my skills for teaching."
Mr Cuddihy said he doesn't find teaching on TV too different to being in front of a class of children.
He utilises humour and creativity, just as he does in schools. And it helps that he and the other two teachers, Clíona Ní Chiosáin and John Sharpson, are working from real classrooms in Dún Laoghaire, where the show is aired.
"I love using play as a teacher, I think it's how children learn best," Mr Cuddihy said. "And I think puppets are a fantastic way to help children learn.
"So much is possible with play and humour.
"I feel very proud to be teaching Ireland's children right now and of course I'd love to continue doing that. It's been very busy, but an incredible honour."
He said that to receive recognition from President Michael D Higgins was "amazing" and there had "not been a dry eye" among the team when they received the letter praising the show.
The programme has been watched by thousands of children across Ireland every day from 11am-12pm on RTÉ 2 while Home School Extra is broadcast at 4.15pm. The show is also available on RTÉ Player.
RTÉ is also broadcasting an Irish sign language version of the show at 1pm on RTÉ2. The episodes will also be available on RTÉ Player.
