The Key To... series was developed by the same folks who produce Miquon Math. Though not manipulative dependent, there are scads of illustrations to make the concepts crystal clear. There is also a lot of white space, large type, and only one concept is presented per page.
The Key to ... books are not only easy to learn from, but also to follow along with if you, the teacher, are a little foggy on these topics! These books are self-directed, which means your child works independently at his own pace. What will you do with all your spare time?!?
Answer books are included in each pack, and the answers are clearly worked out, in case you need to bluff your way through!! More than 5 million of these workbooks have been bought since their creation over 30 years ago! Most workbooks are printed on recycled paper.
