Let children's curiosity and investigative skills shine by downloading this Year 3 2-Digit and 3-Digit Numbers Discussion Problem. This resource includes two in-depth problem-solving questions for children to showcase their knowledge and understanding of both addition and subtraction. Both questions require a secure level of skill, and we would recommend children use these after they've worked their way through our accompanying resources for this lesson.

Use as a challenge activity in class as a paired or group task. Alternatively, this could be used in an intervention group to challenge children's thinking, or display one of the problems and open up the discussion to the whole class; the choice is yours! An example answer is included for children to compare their results with.
