X3, then DOUBLE it
Reverse the calculation if that makes it easier

11. 7 x 8 = 56. Just remember - 5,6,7,8 Reverse the calculation
7x table - tips
7 x 8 = 56. Just remember - 5,6,7,8 Reverse the calculation
4 rows of 7 (4 x 7). Count them up - there are     o o o o o o o     o o o o o o o     o o o o o o o     o o o o o o o It is the same as 7 x rows of 4.     o o o o     o o o o     o o o o     o o o o     o o o o     o o o o     o o o o

12. 8x table – tips
The products are always EVEN
X4 then DOUBLE it
The unit digits have a regular pattern - they go down in 2s

13. The tens go up but the units go down
9x table – tips
The tens go up but the units go down
    1 x 9 = 9     2 x 9 = 18     3 x 9 = 27     4 x 9 = 36     5 x 9 = 45     6 x 9 = 54    
The digits of the products add up to 9     18 = = 9     27 = = 9     36 = = 9
