## Introduction

Workshop 10 focused on the importance of using a variety of approaches and strategies when teaching and learning mathematics.Time was spent discussing inferential statistics and in particular deferred material which will be examined for Leaving Cert. 2015. Activities on problem-solving and an overview of the process of lesson study were also gone through on the day. If you missed workshop 10 or want to go back over some of the activities done on the day, you’ll find videos of the full workshop and all the resources used or references during the workshop below.You will find all resources used in workshop 7 here including videos of the full day.
