## Unit 1

**MGSE5.OA.1**Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

**MGSE5.OA.2**Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them.

**MGSE5.NBT.1**Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.

**MGSE5.NBT.2**Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.

**MGSE5.NBT.5**Fluently multiply multi-digit whole numbers using the standard algorithm (or other strategies demonstrating understanding of multiplication) up to a 3-digit by 2-digit factor.

**MGSE5.NBT.6**Fluently divide up to 4-digit dividends and 2-digit divisors by using at least one of the following methods: strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations or concrete models. (e.g., rectangular arrays, area models)
