Material Detail

Simplifying searches. With a few mouse clicks or screen touches, anyone helping a 7 year old (second grader) to add whole numbers will have immediate help. Page numbers and click on age appropriate Internet links to OER (also open access) materials on adding whole numbers are provided. No more typing needed.

The ever expanding website, k-12math.info, is an Editor's top 5 star MERLOT open access (no cost, no sign in) education resource; twice nominated (2016 and 2018) for  the United Nations' World Summit on the Information Society (WSIS) award in e-learning; and a UN WSIS project Ambassador. Textbook and grade level oriented OER series like Singapore Math, Bangladesh Mathematics, Houghton Mifflin, McGraw-Hill, Siyavula (South Africa/OpenSTAX ), CK-12, Khan Academy, A+ Click and others have been cataloged to help locate where and how 1000 of the most common terms (like “adding whole numbers”) are used. Over 4,000 OER/Open access links are provided (these integrating efforts started in 2009 and continue to the present).
