Our discussion problems are designed to enhance the reasoning and problem-solving skills of children through group work. This Year 6 Number Line to 10,000,000 Discussion Problem includes an in-depth question about numbers up to ten million where children use clues to find a number. An answer page is included with this resource, which provides an example answer for the question, though more answers may be possible. Encourage children to mark their own work in to help them develop their self-corrections skills.
