Fiona,
please do see some of the resources from PolarStar, a past European project where we did produce material in Irish. Curious Minds have a wealth of activities and you can search for those in Irish directly at https://www.sfi.ie/engagement/curious-minds/teacher-resources/classroom-resources/.
Some are in the process of being rebranded, so if you have used one in the past, it will be back again shortly. Amazing Triangles is one of my favourite, and the new Irish version has just been released.
If other teachers have go-to sources of material in Irish, please do share.
