Multiplication chart 1-40

A multiplication chart 1-40 is a 40 × 40 grid of products, from 1 × 1 = 1 to 40 × 40 = 1,600. Find one number down the left side and the other across the top: the square where they meet is the answer. Print it below in color, in black and white or blank, on US Letter or A4.

Print the multiplication chart 1-40

On one US Letter page the products print at 5 points, smaller than most printed text, so the one-page chart suits a wall or a binder you read up close. For everyday use, print the large-print version: four pages of 20 × 20 squares with the products at 9.7 points. The blank chart comes as four pages too, because a one-page square (4.6 mm) is too small to write a four-digit answer in.

Black and white and blank charts

The black and white chart uses gray shading that copies well on a school photocopier. The blank chart keeps the numbers 1 to 40 along both edges and leaves every square empty to fill in.

How to read the 1-40 chart

  1. Find 36 in the colored column on the left and 27 in the colored row across the top.
  2. Follow row 36 across and column 27 down. They meet at 972, so 36 × 27 = 972.
  3. Division works backward: to find 972 ÷ 27, go down column 27 to 972 and read the number at the start of that row, 36.

The 1-40 chart in numbers

Our chart generator counted these. We count 36 × 27 and 27 × 36 as one fact, because they match on opposite sides of the diagonal.

So the 1-40 chart has 1,600 squares but only 517 different answers. The most repeated answer is 120, which appears 12 times.

Square numbers from 1 to 40

The diagonal from the top left corner to the bottom right holds the square numbers, each a number times itself. They are the bold squares on the chart.

Tricks for the bigger numbers

  • The 40s: Multiply by 4, then by 10. 40 × 13: 4 × 13 = 52, and 52 × 10 = 520.
  • 31 to 39: Split off the 30, multiply both parts and add. 34 × 7 = 30 × 7 + 4 × 7 = 210 + 28 = 238.
  • Just under a ten: Round up, then take one group away. 39 × 6 = 40 × 6 − 6 = 240 − 6 = 234.
  • Squares that end in 5: For 35 × 35, multiply the 3 by the next number, 4, to get 12, then write 25 after it: 1,225.

34 × 7 as a rectangle cut at 30: 210 + 28 = 238.

Splitting a number this way is the distributive property, the same idea as Common Core 3.OA.B.5: "Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)"

Who needs a chart this big?

In the US, Common Core 3.OA.C.7 ends with "By the end of Grade 3, know from memory all products of two one-digit numbers." In England, Year 4 pupils should "recall multiplication and division facts for multiplication tables up to 12 × 12". Neither goes past 12 × 12, so a 1-40 chart is for looking answers up: checking long multiplication, finding factors and spotting patterns. To learn the facts themselves, start with the multiplication chart 1-12 and the times tables worksheets.
