About K-12math.info - Mission Statement
Teachers and students by providing grade/age appropriate supplemental materials quickly.
Department heads and content specialists by providing information on currently available materials quickly.
Curriculum and materials designers by providing information from which they can develop new materials quickly.
The public by providing understanding of what is expected of k-12th grade math learners quickly.
Information sources by providing a model of a user interface that gets users to information quickly.
At this time (September 2015) k-12math.info serves the educational professional
with over 140,000 pieces of information and 4,200 links on 1000 of the most common terms and concepts used in
over 220 elementary and secondary school mathematics textbooks (California state adopted textbooks and others)
and OER materials (CK-12, CNX/ Siyavula, Khan Academy, AAAKnow, and others).
K-12math.info helps the user by providing an easy way to locate resources, definitions, content development,
examples, practice activities, homework, and enrichment activities done by the best developers we have now.
It does this by providing a simple user interface requiring no typing, no signing in, and no lost space on its
screen due to advertising. K-12math.info is seriously concerned with the issue of improving mathematical learning
for the learner (both in learning mathematics and being able to read and write about it), and resource development.
K-12math.info had its origins in a materials’ development project in Thailand in 1969/70. It has appeared in multilingual paper form
in the 1970/80’s. It next took the form of a series of floppy disks in 1980/1990’s with Kinkos handling one of its
best sellers. In August of 2005 K-12math.info went live on the Internet.
Comments on the 1000 terms used in K-12math.info:
1. The list of terms in K-12math.info has not changed in 45 years.
2. No list of terms is complete. But K-12math.info’s list provides enough reference points to aid in research and development of new materials.
3. No developer of elementary and secondary school math has or needs to use all 1,000 terms to have a successful program. A learning community determines its needs.
4. K-12math.info has shown that while content and its distribution change very slowly, the mode of presentation is changing frequently ("new math" of the 60's/70's;"Back to Basics"; "Standards"; "Common Core", and more to come in the future).
5. Terms are grouped under headings to help in searching for them. And in some cases do not reflect the way the authors of materials group the terms.
Please note: www.K-12math.info is not affiliated with any other website of a similar name. K-12math.info has never been funded by any publisher of mathematics materials. On occasion publishers and users who find this website useful, have sent textbooks to be reviewed or gave me information on places where textbook series can be publically reviewed (San Francisco bay area) – always appreciated. Thank you.
