"When we learnt about Switzerland we had someone visit us with St Bernard dogs, which come from Switzerland, and we also had someone bring in all horns and cowbells as well."
As well as postcards, Neil says people have sent gifts to help the children with their learning.
"We've received T-shirts, posters, magnets, and also educational books. A homeschooled student from Australia sent us a book containing Aboriginal paintings so we did some learning around that. I think it's important children learn about the different cultures across the globe."
Pupil Angus Knowles, 4, says learning about Wales was interesting.
"We made a dragon creation and I made the head. We also made a flag for Wales and then tulips and windmills for Holland."
Sadie Treanor, also 4, received a postcard from a family friend for the project.
"One of my uncles sent one a postcard which was really nice."
As well as learning about countries, the pupils have learned interesting facts.
Four-year-old Lucas Urbano says he liked learning the facts so he could share them with his family.
"Mt Everest is the tallest mountain, Dubai has the tallest building and the driest place is Arica in Chile. These facts are very interesting and I share them with Mum too."
As well as learning about other countries, teacher Lizzie Callingham says the project is a chance for family members overseas to connect with their relatives.
"It's also connecting families who haven't been able to connect for a few years. Lots of families are interested in what their relatives are doing and this is a way they can be part of that."
