Patterns that help you remember it
- The last digits repeat in a cycle of 5: 8, 6, 4, 2, 0.
- Every answer is even, because 688 is even.
- Split it into tens and ones: 688 × k = 680 × k + 8 × k.
- Each answer is 688 more than the one before, so you can count on in steps of 688.
Building it from tables you already know
Every answer in the 688 times table is double the answer in the 344 times table: 344 × 6 = 2,064, so 688 × 6 = 4,128. To multiply 688 by 9, multiply by 10 and take one 688 away: 6,880 − 688 = 6,192. To multiply by 11, multiply by 10 and add one more 688: 6,880 + 688 = 7,568. Multiplying by 4 is doubling twice: 688 → 1,376 → 2,752.
Every multiple of 688 is at least 688, so there are none below 100 and 1 below 1,000. A number is in the 688 times table exactly when it divides by 688 with no remainder.
Odd, even and the last digit
Because 688 is even, every answer in its table is even, which is a quick way to catch a wrong answer. Multiplying by 10 always puts a zero on the end: 688 × 10 = 6,880, and 688 × 100 = 68,800. Multiplying by 5 is half of multiplying by 10: half of 6,880 is 3,440.
Using the 688 times table to divide
Every fact also works backwards: because 688 × 7 = 4,816, you know 4,816 ÷ 688 = 7 and 4,816 ÷ 7 = 688. Practising the table and its division facts together halves the work.

Word problems
Times tables are most useful when you can spot them in a question. Try these, then open each one to check:

Answer
7 × 688 = 4,816 pencils. - Tickets cost $688 each. How much do 6 tickets cost?
Answer
6 × $688 = $4,128. - 3,440 chairs are set out in rows of 688. How many rows are there?
Answer
3,440 ÷ 688 = 5 rows. - A plant grows 688 millimetres a week. How much does it grow in 8 weeks?

Questions
What is 688 × 12?
8,256.
What is half of 688 × 8?
688 × 8 = 5,504, and half of that is 2,752, which is 688 × 4. Halving one factor halves the answer.
What is 688 times 0?
0. Any number multiplied by zero is zero, because zero groups of 688 contain nothing.
What is 688 × 7 and 688 × 8?
688 × 7 = 4,816 and 688 × 8 = 5,504. These two are the facts most people find hardest, so they are worth practising on their own.
Is 10,320 in the 688 times table?
Yes: 10,320 ÷ 688 = 15 with no remainder. 10,321 is not, because dividing it by 688 leaves a remainder of 1.
How do I learn the 688 times table quickly?
Learn it in order first, then use the patterns above and practise mixed questions; a few minutes a day works better than one long session.
