5 Times Table Practice: Half of Ten

If this video helped, subscribe to the channel. The challenge works best when you come back every day, and the next table is already waiting.

The 5 times table is half of the 10s

Multiplying by 5 is half of multiplying by 10. For 5 × 8, think 10 × 8 = 80, and half of 80 is 40. This works with any number and it is faster than counting up in fives.

Patterns in the 5 times table

5, 10, 15, 20, 25, 30, 35, 40, 45, 50

• Every answer ends in 5 or 0, and they alternate.
• An even number of fives ends in 0, and an odd number ends in 5. 5 × 4 = 20, but 5 × 7 = 35.
• The tens digits go 0, 1, 1, 2, 2, 3, 3, 4, 4, 5. After the first answer, each one appears twice in a row.

Think of a clock

Look at the face of an analog clock: every number is five minutes further on. The 7 stands for 35 minutes past the hour, and 5 × 7 = 35. The 9 stands for 45, and 5 × 9 = 45. If you can read the minutes on a clock, you already know most of this table.

Test yourself

After the video, check what stuck. Math Engine gives you ten questions on the 5 times table, a hint after each answer, and a review round for the ones you missed. It is free and needs no sign-up.
