This Year 5 Kilograms and Kilometres Discussion Problem encourages children to use their reasoning and problem-solving skills to convert between metres and kilometres, as well as grams and kilograms. The resource presents two in-depth questions that can be answered in pairs or small groups, which promotes self-correction and a desire to find the best way of working out.

An answer page is provided with this resource which includes an example answer for each question, though we de expect children may find more than one answer. Encourage children to mark their own work, or that of a partner, to help them engage in even more discussion and self-correction.
