The Spelling City website features a large base of vocabulary terms used in mathematics that are organized based on skill level and age. Along with terms and definitions, the website also offers lesson plans and teaching resources.
Spelling City's website offers a comprehensive vocabulary list based on the Common Core Math Standards. The lists are also organized by K12 Common Core math content categories such as geometry, measurement and data. Each grade-level category explains what is to be expected from a given math class, and reviews the concepts related to the vocabulary learned. The high school category, for example, explains the concepts of the Real Number System, quantities, the Complex Number System and vector and matrix quantities before breaking the ideas into sections and listing the vocabulary terms for each.
The lists can be downloaded to a teacher or parent account after registering on the website, and may be customized to user needs after downloading. The site includes links for online math curriculums that cater to teaching standards from kindergarten to 8th grade, and printable worksheets and project ideas to aid in teaching. Also included are links to the Learning Games For Kids website, featuring a number of educational video games to reinforce lessons and information retention.
