Like a lot of kids, when I was a middle school and high school student the vocabulary of math often tripped me up. Once I wrapped my head around the meaning of terms I had an easier time understanding and solving the problems. Having a glossary of terms often helped me out. Here are couple of excellent mathematics glossaries for kids.

Math Vocabulary Cards is a free iPad app designed for elementary school students. The app offers exactly what its name implies, a series of flashcards of mathematics vocabulary terms. Each card contains a term, a diagram, and a definition. By default the term is hidden and students have to guess the term based on the definition and diagram. Students can also use the cards with the definitions hidden and the terms revealed. Math Vocabulary Cards can be used in Spanish or English. Simply select a language at the bottom of each card. Students can browse through the entire gallery of flashcards or choose a specific category of terms to study.

Jenny Eather’s A Maths Dictionary for Kids has been around for years now. Every year it is updated with more great content for kids. The dictionary provides simple and clear definitions of math terms. Each definition includes a small diagram or simple activity to illustrate the term’s definition. A Maths Dictionary for Kids does not have a search option, but it doesn’t need one as all definitions appear alphabetically just like in a physical dictionary. Nearly all of the content in the dictionary can be printed.
