If you're looking for a great activity for any whizz kids who have flown through the rest of their 2-digit and 3-digit addition work, try this Year 3 Add 2-Digit and 3-Digit Numbers Discussion Problem worksheet! It comes with two challenging, open-ended problem-solving questions, designed to stretch understanding and promote the application of addition skills in tricky scenarios.

While the resource was created to inspire group discussion, it also works happily as a solo task. There's also no reason why it couldn't be done at home, or with an adult as a discussion partner. It can be flexible to suit your needs, and comes with a handy example answer sheet. Perfect!
