Because of the subject matter of this Year 4 Triangles challenge activity, it's only right that this resource summary has three points...

1. It provides two open-ended, problem-solving questions for those mathematicians who have really got to grips with triangles and are looking to apply their knowledge to more complex challenges.

2. It is really great for prompting discussion in groups as children work together to solve the problems. However, it can also be done by individuals, or with an adult as a discussion partner, at home or at school.

3. It comes with a handy example answer sheet, to help you or your children when it comes to checking answers!
