How do we as teachers build our student's knowledge of important mathematical vocabulary? How do we support our students to make connections while allowing them to demonstrate their thinking? This workshop will show you different ways to incorporate vocabulary into your lessons. We will also explore how to assess the student’s ability to explain their thinking through the presenters adaption of the Think board which is called a Reasoning Board. We will explore how we can use a Reasoning Board as a way to collect data that will direct your future teaching. We will explore the importance of oral language and how we can use it as a form of assessment and feedback. We will look at how we can incorporate these activities across different strands of the curriculum.
