Low Threshold High Ceiling Tasks

This feature focuses on using those tasks which most children can access, beacuse the mathematical content is relatively simple, yet which offer opportunities for children to extend their thinking and reasoning skills through the choices they make.

LTHC was a feature several years ago and so we thought it was about time to update it, particularly in line with the new mathematics National Curriculum (DfE, 2013). We have reflected on what it means to call a task LTHC as well as adding some new thinking to this feature.
