The 20 times table
Also written as the multiplication table of 20. Here it is in full to 20 x 20, with the patterns worth pointing out, the fact children trip on, and free practice that does not need a sign-up.
20 x 1 to 20 x 12
| 20 × 1 | 20 |
|---|---|
| 20 × 2 | 40 |
| 20 × 3 | 60 |
| 20 × 4 | 80 |
| 20 × 5 | 100 |
| 20 × 6 | 120 |
| 20 × 7 | 140 |
| 20 × 8 | 160 |
| 20 × 9 | 180 |
| 20 × 10 | 200 |
| 20 × 11 | 220 |
| 20 × 12 | 240 |
20 x 13 to 20 x 20
| 20 × 13 | 260 |
|---|---|
| 20 × 14 | 280 |
| 20 × 15 | 300 |
| 20 × 16 | 320 |
| 20 × 17 | 340 |
| 20 × 18 | 360 |
| 20 × 19 | 380 |
| 20 × 20 | 400 |
Schools usually require up to twelve. The rest is here for children who want it, and it is where mental arithmetic starts to pay off.
Worth pointing out
Patterns in the 20 times table
- Take the ten times answer and double it. That is the whole table.
- Every answer is the two times answer with a zero written after it.
The easiest way to learn it
Do the two times table, then add a zero. For 20 x 6, two sixes are 12, so twenty sixes are 120. It looks like the hardest table on the page and is one of the easiest.
The fact children get wrong
Nothing genuinely, though children are often intimidated by the size of the numbers until they see the doubling shortcut.
On the abacus
Twenty is two rods to the left, so this table is a place-value shift plus a doubling, which is a single fluid movement for a trained student.
Charts build familiarity. Recall comes from retrieval, a few minutes a day. Print the times tables sprint, or try the free virtual abacus where multiplication becomes bead positions rather than something to memorise.
Common questions
What is the 20 times table?
The 20 times table is 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, continuing to 20 x 20 which is 400. It is the same thing as the multiplication table of 20: each answer is 20 added to the one before it.

Which fact in the 20 times table do children get wrong most often?
Nothing genuinely, though children are often intimidated by the size of the numbers until they see the doubling shortcut.
What is 20 x 12?
20 x 12 is 240. Twelve is the highest multiplier most primary schools require, though children who go further will need up to 20 x 20, which is 400.
Every times table
If the tables are a struggle
The problem is usually not the table
A child who is still counting to work out 20 x 3 has no attention left for 20 x 8. Fluency underneath is what makes the tables stick, and it is what abacus training builds.
