The properties of multiplication are the rules that make multiplying easier. The commutative property says the order doesn't matter: 3 × 8 = 8 × 3. The associative property says you can group three factors any way: (2 × 5) × 7 = 2 × (5 × 7). The distributive property lets you break a hard fact into two easy ones: 7 × 8 = 7 × 5 + 7 × 3.
Third graders don't need the names to use the ideas, but the names help them talk about their thinking. These worksheets show each property with arrays first, then with numbers, so children see why it works. Break Apart Arrays draws a dashed line through an array and asks for the two smaller products.
Every page has an answer key on page 2. Pages print in black and white on US Letter or A4.
CCSS.MATH.CONTENT.3.OA.B.5Apply 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.)CCSS.MATH.CONTENT.3.OA.D.9Identify 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.The commutative property (a × b = b × a), the associative property ((a × b) × c = a × (b × c)), the distributive property (a × (b + c) = a × b + a × c), the identity property (a × 1 = a) and the zero property (a × 0 = 0).
It means breaking a fact into two smaller facts and adding them. To find 6 × 7, think 6 × 5 = 30 and 6 × 2 = 12, then 30 + 12 = 42. An array split by a line shows why it works.
The standard asks children to use the properties as strategies. Many classes also learn the names, so we include a Name the Property page.
