OPERATIONS AND ALGEBRAIC THINKING REPRESENT AND SOLVE PROBLEMS INVOLVING MULTIPLICATION AND DIVISION 3.OA.A.1 Interpret products of whole numbers, e.g., interpret 5 x 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 x 7. EQUAL GROUPS... 006 RELATE ADDITION AND MULTIPLICATION... 007 BUILDING ARRAYS... 008 ARRAY PICTURE CARDS... 009 3.OA.A.2 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. IDENTIFY THE UNKNOWN... 015 3.OA.A.3 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.

For example, determine the unknown number that makes the equation true in each of the equations 8 x? = 48, 5 =? 3, 6 x 6 =? MISSING NUMBERS: MULTIPLICATION... 049 MISSING NUMBERS: DIVISION... 059

UNDERSTAND PROPERTIES OF MULTIPLICATION AND THE RELATIONSHIP BETWEEN MULTIPLICATION AND DIVISION 3.OA.B.5 Apply properties of operations as strategies to multiply and divide. Examples: if 6x4=24 is known then 4x6=24 is also known (Communicative properties of multiplication). 3x5x2 can be found by 3x5=15, then 15x2=30, or by 5x2=10, then 3x10=30 (Associative property of multiplication). Knowing that 8x5=40 and 8x2=16, one can find 8x7 as 8x (5+2) = (8x5) + (8x2) = 40+16=56 (Distributive property).
