Key to Geometry offers a non-intimidating way to prepare students for
formal geometry as they do step-by-step constructions. Using only a pencil, compass, and
straightedge, students begin by drawing lines, bisecting angles, and reproducing segments.
Later they do sophisticated constructions involving over a dozen steps and are prompted to
form their own generalizations. When they finish, students have been introduced to 134
geometric terms and are ready to tackle formal proofs. For grades 4-12

We're in the Pacific Time Zone
Our normal office hours when we answer the phone are 10: 30 AM - 4 PM Monday -
Friday.
We answer email and ship at other times, but normally take Sundays off.
You can fax your purchase orders to 805-237-8639, but it's good to follow up with a phone call in a couple of days to make sure we got it, if you did not receive a delivery confirmation email. Please include an email address with your purchase order in case we have questions and so we can send your delivery confirmation number to you. You can also attach a signed purchase order to an email.
We prefer you ask your questions about products
and availability by
e-mail (barbsbooks@sbcglobal.net), since that gives us more time to prepare a thoughtful answer and
keeps us from playing phone tag. Please remember to put our email address in
your address book if you have a spam filter or you won't ever get your answer
unless you also leave a phone number. We cannot usually tell you immediately over the phone if a
book is here. We have to walk two blocks to check the warehouse, so I usually
have to call you back or email you anyway. We do check our e-mail frequently
throughout the day when we are at home. If we should be out, and you leave a
message on our answering machine, we sometimes cannot hear the phone number
clearly to return your call. Those are some reasons why we recommend you email
us first. If you want us to call you, please leave your phone number and time
zone.
When you do email us, please do not leave the subject blank or just say "Hi" or
"Hello" as the subject. We delete those before opening because a lot of spam
messages look like that.
We have supplied a subject line in the link provided above that will guarantee
your mail will be opened fast.
Or call (800)925-8587 (not before 10 AM or after 10 PM Pacific Time)
