Vertical addition worksheets
Written arithmetic changes shape when it goes vertical. These free printable worksheets stack two-digit addition in columns, with the space above each column that carrying actually needs.

What's on this sheet
The stacked layout is not decoration. Writing numbers one above the other lines up the place values physically, so ones sit with ones and tens with tens, and the column method becomes something a child can see rather than something they have to hold in their head. That is why the standard algorithm is taught this way everywhere.
Why this sheet works
It is also where most avoidable mistakes come from. A two-digit number written one column too far left, a carried digit squeezed in where it cannot be read, an answer that drifts out of its column — none of these are arithmetic errors, but they all produce wrong answers. Practicing the layout on numbers a child can already add is the cheapest way to remove them.
How this one works
One question from this sheet, worked through a step at a time.
2 + 80
2 80 82
- 2 + 80, written in columns. Start at the RIGHT, with the ones.
- 2 plus 0 makes 2. Write 2 in the ones.
- 0 plus 8 makes 8. Write 8 in the tens.
- That is the whole sum: 2 + 80 = 82.
