Here are two songs that are a must for teaching especially from 4th class upwards.

Sinne Fianna Fáil
Atá fé gheall ag Éirinn,
buion dár slua
Thar toinn do ráinig chugainn,
Fé mhóid bheith saor.
Sean tír ár sinsear feasta
Ní fhágfar fé'n tiorán ná fé'n tráill
Anocht a théam sa bhearna bhaoil,
Le gean ar Ghaeil chun báis nó saoil
Le gunni scréach fé lámhach na bpiléar
Seo libh canaídh Amhrán na bhFiann.
