Put your school on the map with Lesson Study 2017-2018


We are delighted to announce that the Maths Development Team will continue support for Lesson Study throughout 2017-2018 and we want your school to be involved.

Sign up for our three-day induction training here (substitution is provided).

Last year 250+ maths teachers from 110 Irish schools participated in our Lesson-Study programme, culminating in a festival of teaching and learning at Maths Counts 2017. This year we want you to join the growing number of participating teachers.

If you participated last year, we’d love to have you back leading Lesson Study in 2017-2018, bringing your experience to our new members. If you haven’t participated in Lesson Study before now is the time to sign up, get your school involved and learn what makes Lesson Study such a worthwhile approach to professional development.

We’re inviting all new participants to attend our three days induction programme in September 2017, so that you”ll be prepped and primed to get Lesson Study up and running in your own school in 2017-2018.

Induction training will provide an introduction to the process of Lesson Study and equip teachers with the knowledge and skills to implement structured problem-solving through  Lesson Study in their own schools.

This year, to make Lesson Study more accessible to all mathematics teachers, we’re planning to hold our induction training at three venues around the country. These are:

  • Dublin
  • Carrick-on-Shannon
  • Limerick

Induction training will take place at these venues over three days (September 27th – 29th) and substitution will be provided for those teachers who attend.
