Five times any number
Multiplying by five has a reliable pattern: the product of 5 and any number always ends in either 0 (for even multipliers) or 5 (for odd multipliers). In 4th grade math with Saxon Math Intermediate 4, Chapter 3, students use this pattern as a self-checking tool — if 5 times any number gives an answer that does not end in 0 or 5, there is a calculation error. The 5s facts are also connected to skip-counting by nickels, making them one of the most intuitive and memorable times tables for Grade 4 students.
Key Concepts
Property Five times any number equals a number that ends in zero or in five.
Examples $5 \times 4 = 20$ $5 \times 7 = 35$ $9 \times 5 = 45$.
Explanation This is just like counting by nickels! Every answer ends in a 0 or a 5. This pattern is a great trick for checking your work. Multiply by an even number for a 0 ending, or an odd number for a 5 ending. It’s a handy shortcut!
Common Questions
What is the pattern for multiplying by 5?
Any multiple of 5 ends in either 0 or 5. Even numbers times 5 end in 0 (e.g., 5 x 4 = 20), and odd numbers times 5 end in 5 (e.g., 5 x 7 = 35).
What are the 5 times table facts?
5x1=5, 5x2=10, 5x3=15, 5x4=20, 5x5=25, 5x6=30, 5x7=35, 5x8=40, 5x9=45, 5x10=50, 5x11=55, 5x12=60.
How can you use the 5s pattern to check your multiplication?
If you multiply 5 by any whole number and the answer does not end in 0 or 5, you made an error. For example, if you computed 5 x 6 = 32, the answer does not end in 0 or 5, so it must be wrong (correct answer: 30).
How are 5s multiplication facts related to money?
Counting nickels is skip-counting by 5. So the 5s multiplication table mirrors the value of a growing number of nickels: 1 nickel = 5 cents, 2 nickels = 10 cents, 3 nickels = 15 cents, and so on.
When do 4th graders learn the five times multiplication facts?
In Saxon Math Intermediate 4, Chapter 3, Lessons 21-30, the 5s facts are reviewed and their ending-digit pattern is explicitly taught as a checking strategy.
How do the 5s facts connect to telling time?
The minute hand moves 5 minutes per number on a clock face, so skip-counting by 5 is exactly how you read minutes. Knowing 5s facts makes reading analog clocks faster and more intuitive.
