### Patterns, Relations, and Algebra for Grades 1-2 Understand patterns, relations, and functions Represent and analyze mathematical situations and structures using algebraic symbols Use mathematical models to represent and understand quantitative relationships Analyze change in various contexts

#### Learning Standards

Students engage in problem solving, communicating, reasoning, connecting, and representing as they:

 2.P.1 Identify, reproduce, describe, extend, and create simple rhythmic, shape, size, number, color, and letter repeating patterns. 2.P.2 Identify different patterns on the hundreds chart. 2.P.3 Describe and create addition and subtraction number patterns, e.g., 1, 4, 7, 10...; or 25, 23, 21.... 2.P.4 Skip count by twos, fives, and tens up to at least 50, starting at any number. 2.P.5 Construct and solve open sentences that have variables, e.g., + 7 = 10. 2.P.6 Write number sentences using +, -, <, = , and/or > to rep-resent mathematical relationships in everyday situations. 2.P.7 Describe functions related to trading, including coin trades and measurement trades, e.g., five pennies make one nickel or four cups make one quart. #### Exploratory Concepts and Skills

• Investigate situations with variables as unknowns and as quantities that vary.
