\(0 \times 7\)
Zero Property of Multiplication: Any number multiplied by 0 equals 0
\(a \times 0 = 0\)
- Recognize that any number multiplied by 0 is 0
- No matter what the other factor is, the result is 0
- This is because you have 0 groups of the other number
\(0 \times 7\) has 0 as one of the factors
According to the zero property, any number times 0 equals 0
\(0 \times 7 = 0\)
\(0 \times 7 = 0\)
• Zero Property: \(a \times 0 = 0\) for any number \(a\)
• Commutative Property: \(0 \times 7 = 7 \times 0 = 0\)
• Universal Rule: This rule works for all numbers
\(1 \times 9\)
Identity Property of Multiplication: Any number multiplied by 1 equals itself
\(a \times 1 = a\)
\(1 \times 9\) has 1 as one of the factors
According to the identity property, any number times 1 equals the number itself
\(1 \times 9 = 9\)
\(1 \times 9 = 9\)
• Identity Property: \(a \times 1 = a\) for any number \(a\)
• Commutative Property: \(1 \times 9 = 9 \times 1 = 9\)
• Universal Rule: This rule works for all numbers
\(2 \times 6\)
Multiplication by 2: Doubling a number or adding it to itself
\(2 \times a = a + a\)
\(2 \times 6\) means doubling 6
Double 6 by adding 6 + 6
\(6 + 6 = 12\)
\(2 \times 6 = 12\)
\(2 \times 6 = 12\)
• Doubling: Multiplying by 2 is the same as adding the number to itself
• Even Result: Multiplying any integer by 2 gives an even number
• Quick Method: Use skip counting by 2s
Multiplication Fact Families 0-5
Multiplication: An operation that combines equal groups of objects
Factors: Numbers being multiplied together
Product: The result of multiplication
Commutative Property: \(a \times b = b \times a\)
Zero Property: \(a \times 0 = 0\)
Identity Property: \(a \times 1 = a\)
- Review patterns: Recognize patterns for each number (0, 1, 2, 3, 4, 5)
- Practice skip counting: Count by 2s, 3s, 4s, 5s
- Memorize facts: Focus on the multiplication table for 0-5
- Check answers: Verify using different methods
• Zero Property: \(a \times 0 = 0\)
• Identity Property: \(a \times 1 = a\)
• Commutative Property: \(a \times b = b \times a\)
• Associative Property: \((a \times b) \times c = a \times (b \times c)\)
\(3 \times 5\)
Multiplication by 3: Tripling a number or adding it three times
\(3 \times a = a + a + a\)
\(3 \times 5\) means tripling 5
Triple 5 by adding 5 + 5 + 5
\(5 + 5 = 10\), then \(10 + 5 = 15\)
\(3 \times 5 = 15\)
\(3 \times 5 = 15\)
• Tripling: Multiplying by 3 is the same as adding the number three times
• Pattern Recognition: Products of 3 follow a pattern
• Quick Method: Use skip counting by 3s
\(4 \times 3\)
Multiplication by 4: Doubling twice or adding the number four times
\(4 \times a = 2 \times (2 \times a)\)
\(4 \times 3\) means quadrupling 3 or doubling twice
Quadruple 3 by adding 3 + 3 + 3 + 3
\(2 \times 3 = 6\), then \(2 \times 6 = 12\)
\(4 \times 3 = 12\)
\(4 \times 3 = 12\)
• Double Double: Multiplying by 4 is the same as doubling twice
• Even Result: Multiplying any integer by 4 gives an even number
• Quick Method: Use skip counting by 4s
