However its very important to avoid erecting an Irish obstacle to learning Irish.
We strongly recommend creating a solid grounding for ALL of your students in the Irish you intend on using to deliver Irish through Irish, at the outset.
Consider giving all students an opportunity to "be the teacher" in setting up your activities (through Irish). This aligns with our tenet that "if you can't deliver it, you don't know it."
When each student has had a go at giving instruction through Irish they'll have better attention and comprehension for receiving and understanding such instructions.
