## Algebra Standard for Grades 3-5

 Expectations
 Instructional programs from prekindergarten through grade 12 should enable all students to— In grades 3–5 all students should— Understand patterns, relations, and functions describe, extend, and make generalizations about geometric and numeric patterns; represent and analyze patterns and functions, using words, tables, and graphs. Represent and analyze mathematical situations and structures using algebraic symbols identify such properties as commutativity, associativity, and distributivity and use them to compute with whole numbers; represent the idea of a variable as an unknown quantity using a letter or a symbol; express mathematical relationships using equations. Use mathematical models to represent and understand quantitative relationships model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions. Analyze change in various contexts investigate how a change in one variable relates to a change in a second variable; identify and describe situations with constant or varying rates of change and compare them.
