Easy Math Definitions For Elementary School

Our 67 page printable math dictionary for kids is an excellent reference for easy Math definitions and math facts.

Where it is expected, our math definitions have formulas with examples from:

  • Mathematics,
  • Geometry, and
  • Algebra. 

These different Math words are gathered from many sources into a concise and comprehensive dictionary for elementary school. All the main K-6 math definitions are here.

So many times the definitions from the lower grades were not kept with the glossaries in text books of the higher grades, so I had to keep lower grade math books handy. 

Also, so many of the definitions are either non-descript or could be better worded for children or for real use. You'll be happy keeping a printable dictionary.

Digital Or Printable. Free.

Print and share - free.

You can print and store this dictionary in your binder for easy reference or your computer or tablet for digital reference.

The free printable PDF downloadable ebook below has all the definitions from all 26 of our online Math dictionary pages. See the alphabetical list below.

Print or read from screen or download. Enjoy!

Printable Math Dictionary: Handy For Class Time!

Some text books or help files simply don't have enough Math definitions or they do not define the elementary and middle school Math terms well.

I know. I've kept other Math books with me during class simply to have easy access to good definitions.

I've searched all these books to pool these definitions and formulas together so that they're handy for your daily reference and to supplement your book's math glossary no matter which grade you're teaching.
