Attached are four activities that are aligned to the CCSS and the CCSD standards that guide students develop a conceptual understanding of algebraic ideas, properties of the number system, and multiplication fluency. #VegasPBS-MATH270.68
5.OA.A.1 - Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
5.OA.A.2 - Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation "add 8 and 7, then multiply by 2" as 2 x (8 + 7). Recognize that 3 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
NV 1.5.5 - Use multiples of 10 to expand knowledge of basic multiplication and division facts.
