By using our discussion problems, you are giving your children great opportunities to develop their reasoning and problem-solving skills through group work, self-correction and discussion with their peers. This Year 3 Add Two Numbers (Across a 100) Discussion Problem presents two in-depth questions where learners are required to use everything they know about addition to find an appropriate answer. Speaking of, we have also provided an answer page with this resource that includes example answers for each question - this is because children may find different answers too. Encourage children to discuss their methods of working and the answers they get with a partner to help them develop even further.
