Why do schools teach up to 12 × 12?

Twelve shows up everywhere in everyday measures — a dozen, 12 inches in a foot, 12 hours on a clock face — so English-speaking curricula traditionally expect times tables to be known up to 12 × 12. Larger 15 × 15 or 20 × 20 charts are handy for two-digit practice and for spotting square numbers.

How can I print a blank multiplication chart?

Set the practice option to “Hide all” (or “Hide half”) and press Print; the printed page keeps the empty cells so it works as a worksheet, and choosing “Save as PDF” in the print dialog gives you a PDF. “New set” reshuffles which cells are hidden, and the PNG export uses the same hidden cells.

What patterns can kids find in the chart?

Each row and column is a skip-counting sequence, the chart is symmetric across the diagonal because multiplication is commutative, the diagonal holds the square numbers 1, 4, 9, 16…, the 5s end in 0 or 5, and the digits of the 9s (up to 9 × 10) add up to 9. Hovering a cell highlights its row and column to make these easy to see.

What is the Chinese multiplication rhyme table?

Chinese pupils memorise 45 short rhymes such as 三七二十一 (“three seven twenty-one”), one for every pair of factors from 1 to 9 with the smaller factor first. Because each pair appears once, the table forms a staircase triangle instead of a square. Switch the site language to Chinese to see and print that version.

✖️Multiplication Table - 12×12 & 20×20 Chart, Practice & Quiz

A clean, interactive multiplication chart you can size from 9 × 9 up to 12 × 12, 15 × 15 or 20 × 20. Hover over any product and its row and column light up, so patterns jump out: each row goes up by the same amount, the square numbers run down the diagonal, and the chart is symmetric because 3 × 7 = 7 × 3. Practice mode hides a quarter, half or all of the cells at random for your child to fill in, then checks every answer at once; the quiz serves random a × b questions, can focus on a single times table, and keeps score and streaks. Print the chart (only the table is printed, blank cells included, so it doubles as a worksheet) or export it as a high-resolution PNG. The Chinese version of this page also includes the classic triangular 9 × 9 rhyme table used in Chinese schools.
