Dimensions Math® G6-8 Textbooks are designed for middle school students. Developed in collaboration between Star Publishing and Singapore Math Inc®, this series follows the Singapore Mathematics Framework and covers the topics in the Common Core State Standards.

The emphasis of this series is on empowering the students to learn mathematics effectively and independently. Depending on the topics covered, different approaches are adopted for the presentation of concepts to facilitate easy understanding by students to internalize concepts and instill in them an interest to explore the topics further.

Each book includes appropriate examples, class activities and diagrams to understand the concepts and apply them. IT skills and values are incorporated as appropriate.

Some features of this series include the following:

  1. Class activities which allow the student to learn mathematics through discovery. Some of the class activities make use of Geometer’s Sketchpad (available at keypress.com).
  2. Worked examples are followed by a similar question (Try It!) so that students can check if they have understood the concepts presented earlier.
  3. An exercise for each lesson including questions in the following sequence:
    • Basic Practice (simple questions involving a direct application of the concepts)
    • Further Practice (more challenging questions on direct application)
    • Maths@Work (questions that apply mathematical concepts to real-life situations)
    • Brainworks (questions involving higher order thinking or an open-ended approach to problems)
  4. Each chapter is followed by a review exercise; the Extend Your Learning Curve activity encourages students to explore mathematical concepts further or apply mathematics in real-life situations, with some questions requiring sentence or paragraph answers to encourage students to reflect on their learning experiences.
  5. The right margins contain remarks on important information, concepts or definitions covered earlier related to the current material to help students recall them, discussion questions, interesting puzzles or facts that are related to mathematics, and some website references.

The answer key at the back of the book provides answers to the Try It! and the problems in the exercises for the Basic PracticeFurther Practice, and Maths@Work questions. It does not include answers to the class activities or the Extend Your Learning Curve activities.

Groundbreaking Work!
Format: Hardcover
The first thing to note here is the author is trilingual. He's Polish by birth, writing very credibly in his second language (English), and using his Nihongo to translate Japanese source materials into English for the first time. Wow! As a historian myself, I only wish I had those kind of language skills. The second thing I'll say is that I learned a lot from the book. I've never seen many of the details the author had dug up. He's doing the same sort of thing that Tony Tully and I did in Shattered Sword--using the Japanese air group records, and Senshi Sosho, as well as more modern sources from Japanese historians like Mori Shiro--to paint a much richer picture of the Japanese side of the battle. And in some ways he's doing it better, because his language skills are so formidable that he was able to look at more Japanese source material than we were. Bravo Zulu. An example: for years American historians have portrayed the placement of Shoho in front of the Japanese invasion force as either 1) a bait force to lure the Americans away from Japan's main carrier force, or 2) at the very least an indication of extreme Japanese hubris, by sticking a lone light carrier's neck out waaaay too far. It turns out that there were a number of Japanese staff officers that were appalled at the dangers Shoho was being exposed to, and lobbied for her inclusion in the main carrier force instead (which would have made a lot more sense, frankly, and was a detail I hadn't known before.) But those officers were overridden in the name of keeping at least some air cover near the invasion force. What this demonstrates is that even here, at the very beginning of the war, the Japanese were already over their skis in terms of the fragility of their air power. All in all, Piegzik's book is a very welcome contribution to the English literature on the Pacific War. He has also written what is (from all accounts) a fine series on the Indian Ocean raid that I need to pick up as well. I am really looking forward to his continued publications in the field.

An excellent book
Format: Hardcover
An excellent book, based on Japanese documents—offering, for the first time, such a detailed account of the first aircraft carrier battle, presented from the Japanese perspective. It covers every Japanese aircraft involved, as well as the fates of their naval aircrews. A must-read for anyone interested in World War II in the Pacific.

Good Book, not Parshall though
Format: Kindle
The author uses more Japanese terms than any similar book that I've read but uses western naming conventions for Japanese people. I don't quite know what to think. Good diagrams.
