How it works
This four times table chart runs from 4 × 1 = 4 to 4 × 12 = 48, and Go up to × 20 carries it to 4 × 20 = 80. Each fact's route is in the list All 20 facts, further down.

Double, then double again
4 is 2 × 2, so any 4s fact is a 2s fact doubled. For 4 × 7, double 7 to 14, then double 14 to 28. A pupil who knows the doubles has the whole 4 times table chart in two steps a line.
Quiz it Mixed up
In order, each answer is the one above plus 4, so the column can be filled by counting. Set Order of the facts to Mixed up under More options before New quiz, and every answer has to be doubled out.
- Stuck on 4 × 12? Double 12 twice: 24, then 48.
- A 4 times tables chart halves into the 2s: 4 × 9 = 36, so 2 × 9 = 18.
Questions and answers
How do I know if a number is in the 4 times table?
Look at its last two digits only. If they make a multiple of 4, so does the whole number: 1,368 ends in 68, which is 4 × 17, so 1,368 is in the 4s. It works because 100 is 4 × 25.
