VocabularySpellingCity has created these fourth grade math word lists as tools teachers and parents can use to supplement the fourth grade math curriculum with interactive, educational math vocabulary games. Simply choose a list from a particular math area, and then select one of the 25 learning activities available. The material for these lists was specifically designed to be used in a fourth grade math class.

The math vocabulary lists are based on the Common Core Fourth Grade Math Standards. VocabularySpellingCity ensures that these academic vocabulary lists are level-appropriate for fourth graders. Teachers can import these lists into their accounts, and edit or add to them to suit their purposes.

Common Core State Standards Overview for Fourth Grade Math

Algebraic Thinking View Our Lists	Use the four operations with whole numbers to solve problems. Gain familiarity with factors and multiples. Generate and analyze patterns.
Number & Operations in Base 10 View Our Lists	Generalize place value understanding for multi-digit whole numbers. Use place value understanding and properties of operations to perform multi-digit arithmetic.
Number & Operations - Fractions View Our Lists	Extend understanding of fraction equivalence and ordering. Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers. Understand decimal notation for fractions, and compare decimal fractions. Use equivalent fractions as a strategy to add and subtract fractions.
Measurement & Data View Our Lists	Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit. Represent and interpret data. Geometric measurement: understand concepts of angle and measure angles.
Geometry View Our Lists	Draw and identify lines and angles, and classify shapes by properties of their lines and angles.
