One brilliant organistion in Dublin is Fáilte Isteach- this is a group made up of older citizens who volunteer to teach english. This idea is a great support to families who have moved here and may not have a level of english, being able to communicate is an integral part of feeling at home in their new country. There are numerous Fáilte Isteach clubs operating all around Ireland, one of which is only a short drive from my school.
After the conflict in Ukraine started, my school organised bake sales each term where children brought in baked goods and sold them to the greater school community in order to raise funds.
