I have used a number of Bond No-Nonsense textbooks over the years. I fully recommend them for various reasons. The pages are not 'crowded' with information: there are a sufficient number of examples on each page: the Challenge Yourself box allows children to 'feel good' about their understanding of the subject: children enjoy assessing their own handling of the work: there is on-line support with further examples, which allows re-visitng of subjects.
If parents are concerned about methodology, each page starts with an explanation and example of the work to be covered.
