Math Academic Vocabulary - Grade 4 Year-Long Math Dictionary

Vocabulary words are a crucial part of learning not only English, but also Math standards! Academic vocabulary is much more difficult for students (and people) to learn. They need to be taught explicitly and studied in order to recall and apply them in context.

I have been using a personal dictionary for our English vocabulary words but needed something to better teach my math vocabulary words as well! Thus, the math vocabulary dictionary was created.

To create this resource, I utilized materials created by Illustrative Mathematics to use alongside as an additional resource. This math dictionary aligns with terms used in the curriculum with some additional popular math terms. Although it aligns with this curriculum, it can be used amongst many other math programs as well.

There are three different variations of this math vocabulary resource for you to chose the one that works the best for your class!

• Sentence Starter Version- standard based/unit grouped math academic vocabulary words grouped together with blanks for important parts of the definitions for students to fill in. Students will have to also add the examples for the terms.
• Filled- In Version- standard based/unit grouped math academic vocabulary words grouped together with the definitions pre-filled in. Students would have to add their examples of the key terms. You can also use this as a teacher guide and answer key when students are filling out their own.
• Vocabulary Terms ONLY Version - this version only has the vocabulary terms for the year pre-filled in. This allows you to fill in the definitions that your specific curriculum may use. There is a white box option or an option with lines to help with student writing.
• Each version has more ink-friendly printable option. This takes away the large chunk of black border at the top of the previewed pictures. The ink friendly version is not picture in the previews at this time, but is included in the final download. I recently updated this product to include this.
• In each version, there is an additional page that is completely blank in case your curriculum or standards need additional academic terms that I have not already included in this resource.

Topics Covered in this resource:

• Factors and Multiples
• Prime and Composite Numbers
• Fractions (Common denominators, equivalent fractions, decomposing, unit fractions)
• Mixed Numbers (improper fractions)
• Multiplicative Comparison (equal groups, patterns)
• Division and Multiplication (with partial products/quotients, base-ten model, remainders, area model)
• Angles (acute, obtuse, right, straight, protractor)
• Lines (segment, vertex, ray, line segment, endpoints, parallel, intersecting, perpendicular)
• Symmetry (line of symmetry)
• and more!
