Indicators for grade 7
1.Represent and analyze patterns, rules and functions with words, tables, graphs and simple variable expressions.
7.Justify that two forms of an algebraic expression are equivalent, and recognize when an expression is simplified; e.g., 4m = mm + m + m or a * 5 + 4 = 5a + 4.
8.Use formulas in problem-solving situations.
