Delve deeper into the world of subtraction with this fun and engaging Year 3 Subtract Two Numbers (Across a 100) Discussion Problem. The resource includes two in-depth questions that require children to use their reasoning and problem-solving skills to work through. We suggest letting children work in pairs or small groups for these tasks, allowing them to find the best ways to work out their answers, and further develop their skills.

An answer page that includes an example answer for each question has been provided, but children may find alternatives. Allowing children to mark their own work, or that of a partner, may encourage more discussion and self-correction.
