6 Links to Multiplication Tips Multiplication tables and facts can be tricky. Click on the number(s) you are having trouble with and you will be taken to some tips. 3 & 4 5 & 6 7 & 8 9 & 10 1 & 2

7 Multiplication Tips for 1 and 2 1 Any number multiplied by 1 equals that number. 8 x 1 = 8 3 x 1 = 3 1 x 5 = 5 2 Whenever you multiply by 2, the answer will be an even number. Multiplying a number by 2 is just like adding that number to itself. 6 x 2 = 12 6 + 6 = 12

8 Multiplication Tips for 3 and 4 3 To check your answer of something multiplied by 3: separate the digits in the answer and add them together until you get a single digit. It should be a multiple of 3. 3 x 6 = 18 1 + 8 = 9 = multiple of 3 4 Take the number multiplied by 4. Double it, then double that answer for your final answer.

9 Multiplication Tips for 5 and 6 5 The answer of an even number times 5 ends in 0. The answer of an odd number times 5 ends in 5. 6 Any number multiplied by 6 equals an even number. When you multiply 6 by an even number, the answer will end in that even number. 6 x 2 = 12 6 x 4 = 24 6 x 6 = 36 6 x 8 = 48

10 Multiplication Tips for 7 and 8 7 Sadly, there are no real tips for the 7s in multiplication. You simply need to memorize them. 8 In the answer of a number multiplied by 8, the second digit is a multiple of 2. Also, as you multiply up, that second digit counts down (by 2s) from 8 to 0. 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48

11 Multiplication Tips for 9 and 10 9 As you multiply by 9, the first digit of the answer increases while the second digit decreases. 9, 18, 27, 36, etc. 10 Anything multiplied by 10 will end in a zero. Take the number you are multiplying by 10 and stick a zero on the end for your answer.

12 Equation quiz Start with Question A Decide on an answer Click anywhere to reveal one answer at a time Not understanding these problems? Click here for help! A.8 x 7 B.9 x 2 C.3 x 6 D.10 x 4 E.5 x 5 F.7 x 1 G.4 x 9 H.6 x 5 I.2 x 3 J.8 x 10 A. 56B. 18 C. 18D. 40 E. 25F. 7 G. 36H. 30 I. 6J. 80

13 Equation quiz help A.8 x 7 = 56. 8 x 10 = 80. Because 7 is 3 less than 10: 8 x 3 = 24. 80 - 24 = 56. B.9 x 2 = 18. This problem is the same: 9 + 9 = 18. C.3 x 6 = 18. 6 x 2 or 6 + 6 = 12. 12 + 6 or 6 x 3 = 18. D.10 x 4 = 40. Take the 4 and stick a zero on the end: 40. E.5 x 5 = 25. Multiplying 5 by an odd number so the answer will end in 5. 5 x 10 = 50. 5 x 5 = half of 5 x 10 = 25. F.7 x 1 = 7. Multiplying by 1 so the answer is the other digit: 7. G.4 x 9 = 36. 9 x 2 = 18. 9 x 4 = double 9 x 2 = 18 + 18 = 36. H.6 x 5 = 30. Multiplying 5 by an even number so the answer will end in 0. 6 x 10 = 60. 6 x 5 = half of 6 x 10 = 30. I.2 x 3 = 6. These problems are the same: 2 + 2 + 2 = 3 + 3 = 6. J.8 x 10 = 80. Again, take the 8 and stick a zero on the end: 80.

15 Challenges! 5 x4x3x2x 1 12 x 5 20 x 6 11 x 9 100 x 10 I know these problems are harder than the ones you have been doing, but try them! You may be surprised what you can do. Click here for Answers

16 Answers to Challenges 5 x 4 = 20 20 x 3 = 60 (2 x 3 = 6 then put the 0 on the end) 60 x 2 = 120 (6 x 2 = 12 then put the 0 on the end) 120 x 1 = 120 Answer = 120  12 x 5: 10 x 5 = 50. Add two more 5s to get 12 x 5. 50 + 5 + 5 = 60 12 x 5 = 60  20 x 6 = 120 (2 x 6 = 12 then put the 0 on the end)  11 x 9: 1 x 9 = 9. For 11 x 9, put two 9s next to each other. 11 x 9 = 99  100 x 10: Put the 0 from 10 on the end of 100. 100 x 10 = 1000
