5.OA.1.1(DOK Level 1) Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. 5.OA.1.2(DOK Level 1) Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. 5.NBT.1.1(DOK Level 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. 5.NBT.1.2(DOK Level 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. 5.NBT.2.5(DOK Level 1) Fluently multiply multi-digit whole numbers using the standard algorithm. 5.NBT.2.6(DOK Level 2) Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using 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, rectangular arrays, and/or area models. 5.NF.2.3 Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. 6.NS.2.2(DOK Level 1) Fluently divide multi-digit numbers using the standard algorithm.
