Our discussion problems are designed to get children talking about their work, their answers, and their methods of working out. This helps them to develop their reasoning and problem-solving skills and find the most efficient methods of calculation. This Year 4 Add Two 4-Digit Numbers - One Exchange Discussion Problem is a great way to get children using their reasoning and problem-solving skills with addition of 4-digit numbers.

We have included an answer page that includes an example answer for each of the questions, but there may be more possible answers. We suggest letting your children mark their own work, or that of a partner, to encourage more discussion and self-correction.
