Enthusiast Jenny Eather is the creator of an unique online resource for grade school mathematics students. Called A Maths Dictionary for Kids, the site has over 400 entries arranged alphabetically that explain key math terms and concepts in a simple, straightforward manner. Besides giving definitions, each topic has an interactive activity that demonstrates its use and significance. Some of the activities are quizzes that let the students practice what they have learned, while others show the students how to achieve the correct results based on their own inputs. The friendly interface and relevant content should let children have fun and learn at their own pace.
