Standard: Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 Standard: Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. Standard: Use place value understanding to round whole numbers to the nearest 10 or 100. Theme: Use place value understanding and properties of operations to perform multi-digit arithmetic For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends. Standard: Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. (This standard is limited to problems posed with whole numbers and having whole-number answers students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).) Assess the reasonableness of answers using mental computation and estimation strategies including rounding. Represent these problems using equations with a letter standing for the unknown quantity. Standard: Solve two-step word problems using the four operations. Theme: Solve problems involving the four operations, and identify and explain patterns in arithmetic Standard: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 Standard: Understand division as an unknown-factor problem. Relating Multiplication & Division 3.OA.6 Standard: Apply properties of operations as strategies to multiply and divide. Theme: Understand properties of multiplication and the relationship between multiplication and division Multiplication & Division Properties 3.OA.5 For example, determine the unknown number that makes the equation true in each of the equations 8 Standard: Determine the unknown whole number in a multiplication or division equation relating three whole numbers. Standard: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. Standard: Interpret whole-number quotients of whole numbers, e.g., interpret 56Īpplying Multiplication & Division 3.OA.3 Standard: Interpret products of whole numbers, e.g., interpret 5 Theme: Represent and solve problems involving multiplication and division Course Name: Grade 3 Math Mastery and Test Preparation – Practice Tests and Workbooks: CCSS Aligned
