No answer key?
I love it so far, but I can't figure out where the answer key is for the review exercises. I've been struggling with a problem and can't seem to get the answer right.... Just show me the answer already!
Tons of content!
This book is big because of all of the videos and interactives. It took a while to download but it's worth it! It shows up in the
Iibrary when you buy it but iBooks doesn't let you open it until it finishes downloading. The hands on demos are really cool and no other book has stuff like this.
effective text for middle schooler
I was intrigued by this book and the low price encouraged me to try it out. I already know trig, so I gave it to my middle school aged child for some late summer amusement before school starts. He took algebra at school last year, and was at a good point in his math education to start on this text. We both like the mix of written text, interactive features and animated lectures, and all of the parts I have looked at are accurate, rigorous and presented in a clear and logical way. He has now completed the first 8 chapters, and has gained a good conceptual grasp of the topics covered. The exercises are good, although there are fewer than in a traditional text. We felt this was a good feature, as it allowed him to learn a lot in a short period of time. Nonetheless, we would welcome a companion "workbook" for building fluency. Now that he is nearing the end of the book, he is eager for the publication of the next School Yourself volume, Calculus.
