 * ** Standard ** || ** Week1 **  ||  ** Week 2 **  ||  ** Week 3 **  ||  ** Week 4 **  ||  ** Week 5 **  ||  ** Week 6 **  ||
 * **3.OA.1 ** Interpret 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. // ||  X   || || || || || ||
 * **3.OA.9 ** Identify arithmetic patterns (including patterns in the addition table or Multiplication table), and explain them using properties of operations. //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.// ||  X   || || || || || ||
 * **3.MD.7a ** Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. ||  X   || || || || || ||
 * **3.NBT.3 ** Use place value understanding and properties of operations to perform multi-digit arithmetic. Multiply 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. (A range of algorithms may be used.) ||  X   || || || || || ||
 * **3.OA.3 ** Represent and solve problems involving multiplication and division. 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. ||  X   ||   X   || || || || ||
 * **3.OA.5 ** Understand properties of multiplication and the relationship between multiplication and division. Apply properties of operations as strategies to multiply and divide. 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.) (Students need not use formal terms for these properties.) || ||  X   ||   X   ||   X   ||   X   ||   X   ||
 * **3.OA.7* **<span style="font-family: Gotham-Book,sans-serif; font-size: 9pt;">Multiply and divide within 100. Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of one-digit numbers. ||  X   ||   X   ||   X   ||   X   ||   X   ||   X   ||
 * **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;">3.OA.8 **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;">* Solve problems involving the four operations, and identify and explain patterns in arithmetic. Solve 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. (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).) ||  X   ||   X   ||   X   ||   X   ||   X   ||   X   ||
 * <span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;">3.OA.6 Understand properties of multiplication and the relationship between multiplication and division. Understand division as an unknown-factor problem. For example, divide 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. || || ||  X   ||   X   ||   X   ||   X   ||
 * **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;">3.OA.4 **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;"> Represent and solve problems involving multiplication and division. Determine 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 = ?. || || ||  X   ||   X   ||   X   ||   X   ||
 * **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;">3.OA.2 **<span style="font-family: Gotham-Book,sans-serif; font-size: 10pt;"> Represent and solve problems involving multiplication and division. Interpret 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. || || ||  X   ||   X   ||   X   ||   X   ||
