Identifying Operations
Detailed App Info:
Application Description
Learn how to identify math operations with this Common Core standards aligned app.
Students will:
• Identify four types of operations, their symbols and when to use them
• Practice addition, subtraction, multiplication and division math facts
• Create and solve problems for four types of operations

Common Core Standards
3.NBT.3Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 * 80, 5 * 60) using strategies based on place value and properties of operations.
3.OA.1Interpret products of whole numbers, e.g., interpret 5 * 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 * 7.
3.OA.2Interpret whole-number quotients of whole numbers, e.g., interpret 56 * 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 * 8.
3.OA.3Use 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.
3.OA.4Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 ? = 48, 5 = * * 3, 6 * 6 = ?.
3.OA.5Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 * 4 = 24 is known, then 4 * 6 = 24 is also known. (Commutative property of multiplication.) 3 * 5 * 2 can be found by 3 5 = 15, then 15 * 2 = 30, or by 5 * 2 = 10, then 3 * 10 = 30. (Associative property of multiplication.) Knowing that 8 * 5 = 40 and 8 * 2 = 16, one can find 8 * 7 as 8 * (5 + 2) = (8 * 5) + (8 * 2) = 40 + 16 = 56. (Distributive property.)
3.OA.8Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
