In 2023, Brisbane Catholic Education schools have embarked on a professional learning journey focused on implementing Challenging Tasks in primary Mathematics classrooms. By partnering with Dr. James Russo and Jane Hubbard, schools have developed their understanding of structured inquiry centred around challenging tasks. In this session, we will share stories of success where the impact has been greatest, and future steps scaling this work across Brisbane Catholic Education schools. Teachers will leave with an understanding of using Challenging Tasks in their Mathematics classroom, as well as how these can be leveraged to build an engaging approach to Maths in a primary school.
