1. The Efficient Learning of Multiplication Tables
Elizabeth Anderson
Glenavon School

2. Principles
The Twos: If child knows doubles from addition the two times tables are at hand
The Fives: May know from telling the minutes on a clock for time
May know multiply even number by 5 and is half the even number with a 0 added
Or may know a x 5 = ½ (a x 10)

3. The nines – a x 9 where a is a single digit the answer always adds up to 9.
The first digit in the answer is a – 1
Display fingers with a finger folded – on left of finger tens, on right of finger ones.

4. Skip counting
Skip counting in 2’s, 3’s, 4’s and 5’s helps with those tables

5. Easy Parts
If chn know easier parts can breakdown more difficult parts, eg 6 x 6 = 36 may be used to work out 8 x 6 by noting
8 x 6 = 2 x x 6 = = 48

6. Twice as much
Finding facts that are 2ce as much as a known fact eg 2 x 8 = 16
leads to 4 x 8 = twice 16 = 32

7. The Ones
Chn learn y x 1 = y for any y

8. The noughts
Chn learn that y x 0 = 0 for any y

9. Cummutative principle
Chn learn that a x b = b x a
This shows reflective symmetry along the diagonal axis

10. Method
Chn sit a pre-test of all tables 0x – 9x – 100 Multiplication facts
Make a chart of known facts expected to learn and then coloured when covered and learnt to show rapid progress
Work in pairs to share solution methods and explain their ideas
Ideas reported back to class
At end of lesson child wrote in journal to share learning with a friend

11. Following each lesson the squares learnt were coloured in to show learning
Chn learn 64 out of 100 facts by end of 0x, 1x, 2x, and 5x covered in 1 or 2 lessons depending on capability of class
Focus on remaining ‘difficult’ facts

12. Lesson One
Focus Question: The zero times table – is there anything special about the zero times table. How would you explain it to a friend.
Same for 1 and 2 times tables
Focus question: What can you find out about the 5 times table?
Next test on 64 facts, 0, 1, 2 and 5 times

13. Lesson Two Elicit reactions to test on 64 facts
Focus question: 24 is our special number. Make up number sentences that give an answer of 24.
This was repeated for 48 and 12
Add to chart; 6x4, 4x6, 8x3,3x8, plus 6x8, 8x6 and 3x4, 4x3
Chn put these facts in journal and learn overnight

14. Lesson Three
Focus Task: Think about 9 and represent it in a number of ways. Can you think of ways to explain how you would describe 9 to others?

15. Lesson Four
Focus Task: Explore the answers to the 9 times table to find strategies to help you remember this table
Discuss hand strategy

16. Lesson Five Complete 3x and 4x on chart.
Discuss 3x – skip counting in 3’s
Discuss patterns found in 4x – twice the 2x tables

17. Lesson Six
Focus Question: How would a person who did not know 6x7 and 7x6 work it out?
Eg. If you know your 3 times tables you can work it out. 3x7 =21
so 6x7 = 21+21=42

18. Lesson Seven
Focus Task: Work out 7x8 – this being the fact people find the hardest to remember. Do not use repeated addition.
Eg.7x7 = = 56

19. Post test Test and chart on 100 multiplication facts
Compare results!!!
