Isopsephy Isopsephy (/ˈaɪsəpˌsɛfi/; ἴσος isos meaning "equal" and ψῆφος psephos meaning "pebble") is the Greek word for the practice of adding up the number values of the letters in a word to form a single number. The early Greeks used pebbles arranged in patterns to learn arithmetic and geometry. Isopsephy is related to Gematria, the same practice using the Hebrew alphabet, and the ancient number systems of many other peoples (for the Arabic alphabet version, see Abjad numerals). A Gematria of Latin-script languages was also popular in Europe from the Middle Ages to the Renaissance and indeed its legacy remains in numerology and Masonic symbolism today (see arithmancy).[1] History

Fun Maths printable worksheets > geometry worksheets & problems Below are a number of worksheets covering Euclidian Geometry problems. Geometry is the study of shape, size, position and space. It is after the Greek mathematician Euclid who around 300BC made a list of objects and assumptions (called axioms) from which all results follow. High school math students can use these geometry problems for study purposes.

Trigonometry During this tutorial you will be asked to perform calculations involving trigonometric functiions. You will need a calulator to proceed. We know other things. For example, we know that if the lengths of the three sides of any triangle p, q and r are specified, then the whole triangle is determined, angles included. If you think about this for a moment, you will see it is correct. If I give you three sticks of fixed length and told you to lay them down in a triangle, there's only one triangle which you could make. Top 10 Instructional Strategies to Improve Math Understanding The past four years I have been involved with a Math and Science Partnership grant. One strong component of this grant is the intensive two week professional learning that all participants must attend. Two purposes are always a strong component of this grant.

Mathematics K-12 Learning Standards Mathematics Learning Standards In 2011, Washington formally adopted the Common Core State Standards (CCSS) for English language arts and mathematics. Assessments for these standards will begin in the 2014-2015 school year. Meanwhile, students will continue to be tested on Washington’s 2008 mathematics standards through the 2013–2014 school year. To be tested starting in the 2014–2015 school year. Common Core State Standards for Mathematics
