Strand: Numbers and Operations in Base Ten Fourth Grade students will use place value understanding and properties of operations to perform multi-digit addition, subtraction, multiplication, and division using a one digit divisor. Standard 4.NBT.5 Multiply a whole number of up to four digits by a one- digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. Standard 4.NBT.6 Find whole-number quotients and remainders with up to four-digit dividends and one-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. Strand: Operations and Algebraic Thinking Fourth grade students use the four operations with whole numbers (addition, subtraction, multiplication, and division) to solve problems. Standard 4.OA.3 Solve multi-step word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. a. Represent these problems using equations with a letter standing for the unknown quantity. b. Assess the reasonableness of answers using mental computation and estimation strategies, including rounding.
