Our 2 minute video will cover all that you need to know about the Partitioning Method which can be used when solving addition problems from a Key Stage 2 Maths perspective.

Partitioning Method Explained

We’re now going to solve the same additional sum but using partitioning instead.

Sum: 1732 + 8489

This time we’re going to partition numbers in their Thousands (Th), Hundreds (H), Tens (T) and Units (U).

So, how many Thousands do we have?

Thousands: 1,000 + 8,000 = 9,000

How many Hundreds are we looking at?

Hundreds: 700 + 400 = 1,100

How many Tens?

Tens: 30 + 80 = 110

How many Units?

Units: 2 + 9 = 11

You then add up all of these amounts. This has given us the same answer as we got in the column addition method.

Answer: 10,221

So, there you have it. Two methods of working out 4 digit addition sums. Click to watch our Partitioning Method (Addition of 4 Digits) Key Stage 2 Maths tutorial video on YouTube.

  1. This is fundamentally the same as the column method – the layout has been changed to avoid the confusion over when you are carrying over to the next column. Some students will definitely prefer this, thanks for sharing!
