Multiplication Facts: 0s, 1s, 2s, 5s
Multiplication facts for 0s, 1s, 2s, and 5s are foundational Grade 4 skills in Saxon Math Intermediate 4 (Chapter 3). The zero property: any number multiplied by 0 equals 0 (zero groups of anything is nothing). The identity property: any number times 1 equals itself. Multiplying by 2 is equivalent to doubling; multiplying by 5 is equivalent to skip-counting by fives. Mastering these rules eliminates many common errors and speeds up computation.

Common Questions
What is zero times any number?
Zero. The Zero Property of Multiplication states that any number multiplied by 0 equals 0. Six bags with 0 candies each = 0 candies total: 6 x 0 = 0.
What is 1000 x 0?
0. Even a thousand groups of nothing is still nothing. The zero property works for any number, no matter how large.
What is the difference between 6 x 0 and 6 + 0?
6 x 0 = 0 (zero property of multiplication). 6 + 0 = 6 (identity property of addition). Never confuse the two — multiplying by 0 always gives 0; adding 0 leaves the number unchanged.
A farmer has 6 fields with 0 pumpkins in each. How many pumpkins total?
6 x 0 = 0. The zero property applies: any number times 0 equals 0.
How do you use skip-counting to multiply by 5?
Multiplying by 5 gives the same result as skip-counting by 5s. 5 x 6 = 30, which is the same as counting 5, 10, 15, 20, 25, 30 — six jumps.
