About us Hedyn Cyf

Hedyn Cyf is a family run business established by brothers Gruffudd and Llywelyn Tudur along with their mother Carolyn Tudur.

The company was founded in 2008 with the intention of creating educational materials and resources for teaching young children. So far, we have published a variety of high-quality Welsh language educational books and resources that are now used in many Primary Schools throughout Wales.


Our Products


Darllen gyda Sam

Our first product, ‘Darllen gyda Sam’ was launched in 2011. This is a phonic reading scheme for children aged 3 to 6 years. It is a graded, systematic series of books that enables children to learn, practise and develop their early reading skills. In addition to the simple storybooks, there are extra materials to enhance learning on our website and a booklet containing a step by step guide on how parents can help their child learn how to read. The booklet also offers useful advice, information, and translations for non-Welsh speaking parents who want to help and support their children when they are learning to read Welsh.

 ‘Dysgu Darllen gyda Sam’ has now reached its third publication, it is extremely popular with parents and is used in many Primary Schools classrooms throughout Wales and beyond.

As many as 65,000 books from the series have been sold to date.

Darllen a Deall gyda Sam

Our second publication ‘Darllen a Deall gyda Sam’ was launched in 2015. This series of books, together with a folder of resources and free downloadable material were created to enable young children learn comprehension skills.

In the past, this product has been available as a large pack intended for use in group teaching sessions in schools. However, due to popular demand, a single set of books with a short guidebook and access to free downloadable material from our website is now available for parents to purchase.

Sam and Non characters have been produced as soft toys and are now available to purchase on the website.

Welsh in the Primary School

Cymraeg yn yr Ysgol Gynradd

A guide to Welsh words and phrases published in 2017.

This is a booklet for non-Welsh speaking parents containing an introduction to the most used Welsh words, phrases and sentences that children will hear and use in the Primary School.

At present we have several on-going projects focused on developing and creating more learning materials for children. We hope to continue expanding our line of products in the future. We are eager to provide and improve access for parents who want to be involved in their children’s education and we  hope to assist non-Welsh speaking parents who wish to help their children who are receiving their education through the medium of Welsh.
