This worksheet contains three open-ended problem-solving questions which could be used as an explicit teaching activity, independent activity, during maths rotations or as a guided maths group. The worksheet provides space for students to show their working out by applying a problem-solving strategy. While this was predominately created as part of the Year 3 Problem Solving unit, it would also be a great activity for Year 4 students.
