The 1 times table is technically the easiest of all the times tables — the answer is always the same as the number you're multiplying by. But that "trivial" nature makes it easy to overlook, and skipping it entirely can leave gaps in a child's foundational understanding of what multiplication actually is. This page gives you the full 1 times table, why it matters conceptually, common mistakes to watch for, and a printable worksheet.

Why the 1 times table is trivial (and why it still matters)
The 1 times table has one rule that never changes:
• The identity rule. Any number × 1 equals itself. 5 × 1 = 5. 12 × 1 = 12. There's nothing to memorize — the answer is right there in the question.
• It's the mathematical concept of "identity." In advanced math, 1 is called the "multiplicative identity" because multiplying by it doesn't change anything. Teaching this early plants a seed kids will meet again in algebra.
• It's a good confidence starter. For a child just meeting multiplication, the 1s are 12 easy wins in a row — a perfect place to build the sense that "yes, I can do this."
There's nothing to memorize — focus on the concept instead
Unlike other tables, the 1s don't need memorization tips — they need understanding. Three things to focus on instead:
Make sure the concept clicks. Say it out loud, explicitly: "one group of five" is just five. "One group of twelve" is just twelve. Multiplication by 1 means "one group of that many."
1 × 7 means "one group of 7" → 7
1 × 5 means "one group of 5" → 5
1 × 12 means "one group of 12" → 12
Kids who get this understand what multiplication really is: counting groups. The 1s are where that concept becomes visible.
Connect it to real objects. Show your child one plate with five apples on it. That's 1 × 5 = 5 apples. One plate with twelve marbles = 12 marbles.
1 plate × 5 apples = 5 apples
1 basket × 12 marbles = 12 marbles
1 team × 11 players = 11 players
Making the concept physical makes "one group of" concrete. This is the foundation that "two groups of" (the 2 times table) will build on next.
Use it as a launching pad for the 2s. Once the 1s make sense, introduce the 2s as "two groups of" — same logic, just doubled.
1 × 5 = one group of 5 = 5
2 × 5 = two groups of 5 = 10
(The pattern of "groups of" carries through every table.)
The transition from 1s to 2s is where multiplication actually starts. Get the 1s locked in first, then move on.
Common mistakes to watch for
Skipping the 1s entirely. Some parents and teachers skip the 1s because they seem too easy. But the 1s establish the concept of "groups of" — the whole foundation of multiplication. Skip them and you've skipped the foundation, even if your child seems fine on harder tables.
Confusing 1 × N = N with N + 1. Very rare, but young kids sometimes conflate multiplication and addition. A child who thinks 1 × 5 = 6 has confused "one group of five" (multiplication) with "add one to five" (addition). Make the concept explicit and use physical objects to demonstrate.
Rushing past the concept to move on. The 1s are so trivial computationally that it's tempting to breeze through them in a single lesson. Slow down: use this table to establish what multiplication IS before racing on to harder tables. The extra time pays off across every table that comes after.
When should kids learn the 1 times table?
The 1 times table is typically introduced in 1st or 2nd grade (ages 6-7), often as the very first table taught — sometimes even before the 2s. Some curricula skip it entirely and start with the 2s, but taking time on the 1s helps establish the concept of "groups of" that every subsequent table depends on. If your child is just meeting multiplication for the first time, the 1s are the right place to start.
