McGraw-Hill Education Geometry Review and Workbook (TEST PREP) Paperback – Illustrated, 19 Mar. 2019

The book doesn't deliver the content in a way that it can either consolidate individual ideas, and neither can it develop good questions with concepts a student could adapt and use under test.Everything seems isolated. Some topics it delivers well such as introductions to proofs but I would expect this not to be at a level this book is aimed at, but in a few years further on.It lacks detail on explaining abstraction related to geometric concepts, given the level the books aiming at, it should do more to discuss how geometric axioms exist in their own geometric space... (as an example of lack of rigour)and I have never ever seen a book cover concepts of linear graphs, gradients, as poorly as this one. I was truly shocked, it was so bad it confused me, and I have another book covering this and I also have a good grasp of quadratic equations in various forms, and the problems which use them as part of a solution, so this was a truly epic achievement.It doesn't often cover how to solve problems before the answer key anywhere near as often as it should, which isn't on its own a bad thing in isolation, but the frequency that the questions either require knowledge of information presented many chapters ahead, or which is missing, or has tenuous links to the small amount of actual teaching material in the book for each topic, makes this book useful only for those who are committed to reading multiple books across each topic, which is useful to consolidate and see different sets of problems and their solutions - for an older learner like me.The effort involved in this book will get your child falling behind, not because of the content covered, but in terms of how it takes about 3-5 times longer to get through almost identical material in better written booksThe lack of rigour also means some answers rely on assumptions that need further content (equations of lines derived from formulas in the book are missing), or... for example: giving you the answer, then using the answer in the text showing how to calculate the answer, like a vague check, one which fails as other numbers don't match the other parameters, when using mx+b as part of a step by step solution in the answer key could very simply explain how to solve this without magically defining the answer out of nowhere, then leaving conflicted values that ignore the constant part entirely. It completely violates valid mathematical assumptions through not incorporating the extra bit of maths, to show why the reasoning and answer is sound - which was comical.eg using mx+b to explain a discrepancyBooks aimed at the US education system seem to sometimes have issues in the approach, I think it could help if the US looked at the UK method of teaching up to the ages of 16. many are not bad - I've read some I've gained from, but the course complete style ones lack the ergonomics and style that engages children, with a good amount of information and in a sane chapter order.Finally, if you are an older learner, this book makes you feel slow, its not the other way around, and that extra time isn't helping the knowledge stick because of how poor the content is at communicating concepts
