This is Geata Mata , a free selection of lesson plans and resources for primary school maths classes. Each lesson is comprised of a lesson plan for the teacher (including extra information, timings, etc), exercises for the students, & computational extras.
We create lessons based on "fun" areas of maths (Cryptography, Game Theory, and many more) - while also linking to different areas of the curriculum. This allows students to practice what they have previously learned, while also (hopefully) enjoying and appreciating maths.
Created and designed by a team in the School of Mathematics and Statistics, University College Dublin.
