A good little booklet in a logical order with challenging extensions. Would be useful to have the option formatted not as a booklet so you can keep it simpler for foundation students, and some answers too.

Response from Teachit editor
We're sorry you've found this confusing. Each sheet is intended to be folded in half to create a booklet. Once that is done (according to the page numbers in the bottom corners), it should make sense.

The activities are good and the structure logical. It would be useful to have the pages in the correct order.
