One of anything is that thing
1 × any number equals that number. 1 × 7 = 7, 1 × 9 = 9. There is nothing to calculate — you just say the second number out loud.
Understand what multiplying means
The 1 times table is the perfect place to explain what × actually does. 1 × 5 means one group of 5. Once that clicks, 2 × 5 (two groups of 5) and 3 × 5 (three groups of 5) make sense too.
It works the other way around
Any number × 1 also equals that number. 8 × 1 = 8, 6 × 1 = 6. Remember: multiplying by 1 never changes the other number.
Children typically learn the multiplication tables in Grades 2 and 3 (ages 7–9). The tables of 2, 5 and 10 are taught first, then 3, 4 and 6, and finally the harder tables of 7, 8 and 9. Most children know all tables up to 10 by the end of Grade 3.
What is 1 × 7?+
1 × 7 = 7. Any number multiplied by 1 stays the same as itself.
Why is the 1 times table so easy?+
Because multiplying by 1 changes nothing. You take the other number exactly once, so the answer is always equal to that number.
How do you explain the 1 times table to a child?+
Use objects. Put down one pile of X marbles. The pile contains X marbles — that is 1 × X. Children see immediately that the answer equals the second number.
What grade do children learn the 1 times table?+
