Yesterday, I was working with children on fraction tasks. They had problems to solve and had to display their understanding in a slide show. They took photos of their work and used many resources, concrete and written to demonstrate their thinking.
Out came the misconceptions which we were able to discuss. Some students said they already knew the answers. The teacher working with me in the class explained that modelling had two purposes.
They could use modelling to solve a problem or use modelling to demonstrate how they knew the answer to a problem.
As teachers, we know that modelling is important to solve problems, but yesterday highlighted that modelling is crucial to demonstrate something you already know. This combined with sharing their models and modelling their thinking to another student was powerful learning.
