Thank you for viewing. This is a supplementary workbook for English classes in Canada. I purchased it when my child was in Canada. It's for grades 2, 4, 5, and 6 in Canadian elementary schools, but there's a considerable difference when compared to the grades for English study in Japan. Therefore, please refer to the following, which is my personal opinion: The third photo is a separate Grammar book for grade 4, but I think the content is equivalent to the first year of junior high school in Japan. The fourth photo is for grade 2, but I think the content is perfect for children who are just starting to learn English. They can learn the alphabet, phonics, words, and short sentences. The fifth photo is a page from the end of the grade 6 book, and I think the reading level is about the same as a first-year high school student in Japan. In the Eiken (English Proficiency Test), it would be around Grade Pre-2 or Grade 2. Also, you can download free listening audio from the Popular Book Company Canada website. I listened to it earlier, and the text and listening content matched perfectly, so it seems there haven't been any revisions recently. As shown in the sixth and seventh photos, you can listen to plenty of text and listening questions for each unit. This is a workbook set that can be used for a wide range of ages. You can learn English in English, just like native speakers do, so you can study in the same way as children in Canada, even while in Japan. I think this is good for those who are going to move to an English-speaking country for overseas assignments or study abroad, or for those who want to study English with authentic textbooks from the US or Canada. In the US, workbooks like Brain Quest are used, and this is like the Canadian version, with similar content. I bought each book for 16.95 CAD. That's about 1900 yen. Grade 2 has writing in pencil on 57 pages out of 272 pages. Grade 4 has writing in pencil on 99 pages out of 272 pages. Grade 5, Grade 6, and Complete Canadian Reading are unused and have no writing. If you don't mind the details, thank you.
