Yes, you could print out calendars. But it is nice to have them all together - plus the graphs ready to go. However, the paper used in the 1 meeting book is horrible. They should print on nicer paper - especially since you will be using these books every school day.
I love Saxon. I taught it when I was a public school teacher and have since chosen to use it with my own children at home. It incorporates things so completely and builds on itself every day. I can't say enough good things about it!
This book goes right along with the curriculum.Yes, you could print out your own, but for the price of ink for your printer vs. the price of this book, buy the book. My son loves cutting out the daily strips and writing his date. Sounds silly, but he loves it.You don't 'need' this book, but each lesson starts off with using something out of it. If you're like me and want to stay more organized, not worry about the price of printer/copy ink, and keep your lessons coordinated, then spend the ten bucks and buy this.
