A math dictionary is a type of dictionary that contains mathematical terms, definitions and visual representations. The math dictionary may have a specific or concentrated focus area such as geometry or may contain general mathematical topics related to grade related content. For example, math glossaries that can be found at the end of grade level math textbooks would be considered a more general math dictionary.

Implementation Tips

Have math dictionaries and/or online resources readily available for students to use. Teach students how to look up mathematical terms that they are familiar with and incorporate learning mathematical vocabulary into math lessons.
Test Accommodation
A test taking accommodation for a student might include the use of a math dictionary and/or student created math glossary. The student can use the math dictionary while taking the math test.
Living Math Dictionary
A graphic organizing tool such as the Frayer model can be helpful with learning and categorizing mathematical concepts (see visual example above). The students can build their own mathematical dictionaries using the worksheets by continually adding the mathematical terms into a notebook binder in alphabetical order.


Geometry 4th grade unit
The teacher creates a mathematical word wall with definitions and examples of the terms line, ray, line segment, parallel and perpendicular. Students in class can refer to the word wall as they work on understanding the mathematical concepts and applying understanding to solving mathematical problems.
When learning key mathematical terms such as variable, equation, formula, etc., the student writes the words, definitions and examples in a math glossary or math journal. The student can refer to the math glossary while completing assignments in class.
2nd Grade Geometry
Using an online math dictionary such as [[ | Math Dictionary for Kids ]], the student creates flashcards of different geometric shapes and uses the flashcards to learn the names of the shapes and characteristics of the shapes.
