The 10 times table is the friendliest one to learn: every answer is the number you started with, with a zero on the end. Learn it here with seven practice activities, tricks, worked examples and printable sheets.
To multiply a whole number by 10, write a zero on the end. 7 tens are 70. The digits slide one place to the left and a zero fills the gap.
Work through the activities from left to right. Each one asks a little more of you, and a tick appears when you finish it. Your progress is saved on this device.
Pick the trick that clicks for you. Each one is a different way to the same answer.

10 × 4 = 40
Multiplying by 10 moves every digit one place to the left: ones become tens, tens become hundreds. The empty ones place gets a zero.
10 × 23 = 230
Five is half of ten, so any answer in the 5 times table is half the 10 times answer.
10 × 8 = 80, so 5 × 8 = 40
Nine lots is ten lots minus one lot. Work out the 10s answer, then subtract the number.
10 × 7 − 7 = 63
Eleven lots is ten lots plus one lot. Work out the 10s answer, then add the number.
10 × 7 + 7 = 77
10 is double 5, so work out the 5 times table answer and double it.
5 × 7 = 35, so 10 × 7 = 70
How each answer is found, step by step.
6 tens are 60. The digits slide one place to the left and a zero fills the gap.
The order does not matter: 7 × 10 is the same as 10 × 7. 7 tens are 70. The digits slide one place to the left and a zero fills the gap.
12 tens are 120. The digits slide one place to the left and a zero fills the gap.
17 tens are 170. The digits slide one place to the left and a zero fills the gap.
Ask how many 10s make 80. You know 10 × 8 = 80, so the answer is 8.
Ask how many 10s make 140. Divide to find it: 140 ÷ 10 = 14.
Spotting that a story needs 10 × something is a skill of its own. Work each one out first, then open the answer.
A tray holds 10 cupcakes. How many cupcakes fit on 4 trays?
A pack has 10 pencils. The teacher buys 7 packs. How many pencils is that?

Say each answer out loud before you open it. If you get all ten, try the 60-second test above.

Make a sheet with one or more full times tables to learn from, or with gaps to fill in. Print it, save it as a PDF from the print dialog, or download a picture.
Build a proper test: mix question types, add word problems and a time limit, and print a separate answer key for marking. Every press of New exam gives a fresh paper.
Every fact you learn here turns up in another table too — 10 × 7 is also in the 7 times table.
