This is the standard written method known as ‘short multiplication’. It leads on from the earlier worksheets on ‘Moving towards a standard method’.
Before starting this type of sum a good knowledge of times tables is needed.
The stages are as follows:
Step 1: write the sum out correctly
The question may be put in a different layout eg 38 x 7 =
Make sure it is laid out with the units under each other as shown on the example.
Step 2: multiply the units
Multiply 8 by 7 which 56 or 5 tens and 6 units.
Put the 6 in the answer in the units and place the 5 (tens) in the tens column, under the answer line.
Step 3: multiply the tens
Multiply 3 (tens) x 7 which is 21 (tens).
Add the 5 (tens) to make 26 (tens) or 2 hundreds and 6 tens.
Place the 6 in the tens column and the 2 in the hundreds column.
Easy! 266. All done!!
