MULTIPLICATION
• Multiplication is repeated addition. What this means is multiplication is a fast way of adding a series of numbers.   3 x 5 means to add 3 together 5 times or3 + 3 + 3 + 3 + 3     6 x 4 means 6 added together 4 times or6 + 6 + 6 + 6
Commutative Property
• The commutative property of multiplication simply means it does not matter which number is first when you write the problem.  The answer is the same.   3 x 5 = 5 x 3  (The numbers can be switched around and the answer is the same.)     4 x 7 = 7 x 4   1 x 9 = 9 x 1
Multiplication Factor of Zero
• The zero multiplication facts Multiplication is repeated addition so: 0 x 3 = 0 + 0 + 0 = 0 0 x 7 = 0 + 0 + 0 + 0 + 0 + 0 + 0 = 0 Because of the commutative property of multiplication: 0 x 4 = 4 x 0 = 0 0 x 9 = 9 x 0 = 0
Multiplication Factor of One
• The one multiplication facts Multiplication is repeated addition so: 1 x 4 = 1 + 1 + 1 + 1 = 4 1 x 2 = 1 + 1 = 2 1 x 5 = 1 + 1 + 1 + 1 + 1 = 5 3 x 1 = 3 9 x 1 = 9 Because of the commutative property of multiplication: 1 x 4 = 4 x 1 = 4 1 x 8 = 8 x 1 = 8
Two’s
• The TWO multiplication facts Multiplication is repeated addition so: 4 x 2 = 4 + 4 = 8 (or 2 fours) 3 x 2 = 3 + 3 = 6 (or 2 threes) 5 x 2 = 5 + 5 = 10 (or 2 fives) Because of the commutative property of multiplication: 4 x 2 = 2 x 4 = 8 8 x 2 = 2 x 8 = 16Any number times two is the number doubled! 2 x 7 would be 7 + 7 or 14 6 x 2 would be 6 + 6 or 12
Fives
• The FIVE multiplication facts (Method 1) If you can count by fives, method 1 makes the fives simple 5 x 3 would be 3 fives.  Count by five to the third number.  5, 10, 15  (The answer is 15, because the third number, when you count by fives, is 15) 5 x 6 would be 6 fives.  Count by fives to the sixth number. 5, 10, 15, 20, 25, 30  (The answer is 30.) Because of the commutative property of multiplication: 5 x 3 = 3 x 5 = 15 5 x 6 = 6 x 5 = 30
Ten’s
• The ten’s multiplication’s is a very easy thing to understand. Any number multiplied by ten just adds a zero at the end. For example:
• 2 x 10 = 20
• 30 x 10 = 300
• 155 x 10 = 1550
