Are your children familiar with multiplying 3-digit numbers? Are they ready to move on to something more challenging? This Year 4 Multiply a 3-Digit Number by a 1-Digit Number Discussion Problem might be exactly what you're looking for. Featuring two in-depth, 'meaty' questions, this resource targets reasoning and problem-solving skills by encouraging children to talk about their methods of working out, and potentially find new ways of working. An answer sheet is provided with this resource which includes an example answer. We suggest letting your children mark their own work, or that of a partner, to encourage more discussion and self-correction.
