Key to Geometry complete set workbooks only
This package includes the following items:
The Key To... series is a very self-instructional, unintimidating, programmed learning series. Covering seven basic topics, students can work through these horizontally or vertically. They are ideal for "homework" or a more topical approach to the subject. Presentation is done in a simple, friendly manner, incrementally, and with examples to follow as needed. Workbooks are thin and consumable. Answer keys are recommended. Order by the book or in sets.
We like this series because it encourages children to tackle these subject areas in as much depth as they can, rather than working strictly within the confines of an age-graded math program. Starting in 4th or 5th grade, I purchased a complete set of student workbooks for each child. Book 1 in each topic was put on the school book shelf. When Key to... was assigned, my children were free to work on whatever topic they chose, and they worked as much as they wanted. As soon as Book 1 in any subject was completed, it was replaced by Book 2. My oldest daughter sometimes got so involved that she just kept going!
The steps may seem easy at first, but there is much discovery with a pencil, a straightedge and a compass, just as Euclid used. Forget proofs or measuring angles for now. Buy a quality (Staedtler) compass and learn how to replicate shapes, construct an isosceles triangle from a circle, and much more. There is more logic required in this curriculum than it appears at a glance! Take the time to think about it, and how it was first discovered by grown men. Sometimes I am sure my student can solve a problem without reading the step by step solution, so I challenge him to try and he does it! It has been a huge confidence builder.
My math student struggles with overcrowded information and symbols on a page, but there is lots of space on these pages, which keeps him from getting overwhelmed. The gradual way in which the exercises are done has him learning lots of geometry vocabulary as well, because I say the instructions out loud as he reads along. I have him tell me about his constructions using geo language as well. We try to use 'geometry speak' as much as possible as we discuss the constructions. He is able to read most of the step-by-step instructions independently after I introduce the new words.
Someday, we will have to look at numbers again, but in the meantime, this has been a Godsend. I have a new appreciation for the development of this skill set!
P.S. I am having my 13yo daughter do these books this year, as a respite from Algebra from time to time. It is a good change of pace for her, then she works on algebra again.
