It is suitable for MYP3/4(standard level): Mathematical Task for Criteria C and D where student use the volume and surface are to find the optimal shape for heat pad. Further produce their validations and limitations.
In this investigation students explore the given patterns and find different sequences. The task starts simple but takes it to challenging level in forming quadratic sequences when n is even and odd conditions.
This is a good revision resource for Mathematics GCE O level topic-wise exam questions with answers included. This can be used for IGCSE Mathematics as revision for highly abled students with challenging questions.
