Title: Good problems, but possible mistakes
Review: I like the problems given in the book, but you cannot use this book to purely teach a student algebra. Much of it needs to be explained from your own knowledge, which is fine for me.The biggest gripe I have about this book is the error on page 12. Problem 1 (x + 5 = 3) should have the solution "x = -2", but the book answers say it is "2". This also results in the wrong answer for the puzzle. The answer should be "Twenty-eight", but solving the problem correctly gives you "Gwenty-eight". I would suggest looking for another resource, since I am not sure if the rest of the workbook has errors that may mislead your students.
