Adding two 4-digit numbers with extra reasoning sheets

Children add two 4-digit
numbers with one exchange in any column.
The numbers can be made using place value counters in a place value chart, alongside the formal written method.
When discussing where to start an addition, it
is important to use language such as begin from the “smallest
value column” rather than the “ones column” to avoid any
misconceptions when decimals are introduced later in the year.

After each column is added, ask,
“Do you have enough ones/ tens/hundreds to make an exchange?"
This question will be an important one in this worksheet , as the children do not know which column will be the one where an exchange is needed.
