Multiply 3-digit numbers by 2, 5 and 10
Plenty of practice is needed for children to really get to grips with the written multiplication. With written multiplication there are two distinct methods, the long and the short! Most schools tend to teach the long method first as it is clearer to show exactly what is happening, but it is also important for children to learn the short method, as we are looking to achieve fast accurate calculating.
These pages keep it simple by just multiplying by 2, 5 and 10; three tables that children should know 'off by heart'.The questions have been laid out in the correct way so all that has to be done is:
a. Firstly to multiply by the units, remembering to carry any tens across to the tens column. These are usually placed under the answer.
b. Secondly multiply the tens remembering to carry any hundreds across to the hundreds column.
c. Finally multiply the hundreds and write in the answer, including any thousands.
Once confident with the method children can move on to harder examples, including decimals.
