Rahini from Emirates International School Meadows in Dubai wrote the following:

- I notice in the animation that you keep on adding four cubes but there is an extra cube on the side which is the same.
- When the bundles are of five, seven or nine cubes, the cubes multiply by that certain number plus one.
- I notice that the bundles are bigger and even the numbers are bigger.
- This happens because it depends on the number you're dealing with.

Thank you Rahini.  If you have a go at this task, please do send us your ideas.
