This day and age, the focus in education is for the most part on how we can use technology to make it easier for children to learn. While there is a lot of amazing technology that aims at this, we want to make the case that we should not throw away all the tools that are not part of the new wave. This poster focuses on the use of mini white-boards to engage students in their learning of mathematics. There might be things to learn from this forgotten technology when designing and implementing new technology into mathematics. This project arose from observations of an exceptionally talented teacher. The observation focused primarily on discourse, structure, and tools used. We were intrigued by the way this relatively young teacher utilized an old tool in the lessons to a seemingly great effect.
