Two layouts, and they teach different things

Table style groups sums into organised blocks, up to nine to a page. The repetition is the point: a child sees the pattern across a set rather than working through unrelated questions.

Vertical style puts each sum in the column layout they are actually taught to write, one problem laid out properly with the digits aligned. This is the one to print when the lesson is about carrying rather than about recall.

Print it blank. Or with the answers. Or both stacked into one file.

Digit count is the progression, in one control

In vertical style the digit count sets both operands directly. One digit gives sums from 1 to 9. Two digits gives 10 to 99, which is where carrying is introduced. Three digits gives 100 to 999 and column addition with two carries.

Three separate pages used to cover that progression. It is one number now, and moving a child from single to double digits is a single click rather than a hunt for a different worksheet.

Worth knowing: both numbers in a vertical sum share the digit count, so this will not produce a two-digit plus one-digit problem. If that intermediate step is what you want, the table style with a low range gets closer to it.

Missing-addend mode

Switch it on and the sheet shows the total with one addend hidden. 8 + __ = 15.

That is a different task from adding, and a child fluent at sums will often stall on it, because finding a missing part means subtracting. It is the inverse relationship that all of later arithmetic rests on, and this is the cheapest way to find out whether it is there.

It works in both layouts. Note that it forces the answer version, because the total has to be on the page for the question to make any sense at all.

Zero, and why it is off by default

Include zero adds sums like 7 + 0. It is off to begin with, and it is worth turning on deliberately at some point rather than never.

Adding zero is a fact children get wrong for a surprisingly long time after they are fluent everywhere else, because it looks like a trick and because it almost never appears in practice. A sheet with a few of them scattered through is a two-minute fix for something that otherwise sits unnoticed.

A first practice sheet

Table style, a small range, missing-addend off, blank output. Sixteen problems.

What comes out is a clean page of straightforward sums with nothing to decode. If you also want a marking copy, switch the output to Both and the answer version prints behind it in the same file rather than needing a second generation.

Making the practice stick

• Short and often. Five minutes daily beats half an hour on a Sunday.
• Start below where you think they are, because a sheet finished confidently does considerably more for a child than one abandoned two-thirds of the way down.
• Regenerate rather than reprint. Random mode builds a fresh set every time.
• Print at full scale. Browser margins vary and fit-to-page will quietly shrink the column alignment that vertical style exists to teach.
