Doubling numbers
Solve by using doubling and the times table to multiply these numbers by
a)  = 
b)  = 
c)  = 
d)  = 
e)  = 

How to double numbers First to solve these questions you will need to know your times tables and that doubling is the same as multiplying by 2,.
You now need to use doubling to get to 24 x . The first doubling is the same as (6 x 12 ) x 2 which is the same as 12 x 12 = 144 then a second doubling gives you (12 x 12) x 2 which is the same as 24 x 12 = 288
