Lesson Details

Key learning points

We can use column addition to add 4-digit numbers.
When adding, we regroup 10 hundreds as 1 thousand.
Make sure that any regrouped thousands are added with the values in the thousands column.
Make sure that all regrouped values are added in the correct column.

Common misconception

Incorrectly aligning 3-digit and 4-digit numbers resulting in an incorrect sum.

Practise partitioning 3 and 4-digit numbers into thousands, hundreds, tens and ones to support when placing in columns. This will also support in understanding the relationship between the columns when regrouping.
