Download PDFAddition word problems to 10
Six one-step stories where nothing passes ten, so the hard part is turning the sentence into a sum, not the adding.
Download PDFAddition word problems to 20
The same story shapes carried into the teens, where a child can no longer count the whole answer on their fingers.
Download PDFAddition word problems to 50
Two-digit stories that still fit under fifty, the halfway house between mental addition and the written column.
Download PDFAddition word problems to 100
Numbers big enough that the answer has to be worked out on paper, which is exactly when word problems start being useful.
Download PDFFact families to 10
Six triangles holding three numbers each, the first proof that one addition already contains its own subtraction.
Download PDFFact families to 20
Triangles built from teen totals, so the four related facts stop being findable by counting up from one.
Download PDFFact families to 50
Two-digit triangles for children who know the idea and now need it with numbers they cannot picture as dots.
Download PDFColumn addition, no carrying · #1
Nine two-digit sums where no column ever passes nine, so the algorithm can be learned before carrying is added to it.
Download PDFColumn addition, no carrying · #2
A second full page of the same guaranteed no-carry problems, for the week when the first one nearly worked.
Download PDFColumn addition with carrying · #1
Every single problem here carries out of the ones, by construction, so nobody finishes the page without meeting the idea.
Download PDFColumn addition with carrying · #2
Nine more guaranteed carries, drawn from a different set of numbers so the answers cannot be remembered from sheet one.
Download PDF3-digit addition, no carrying · #1
Hundreds, tens and ones stacked up with nothing to carry, so the only new thing on the page is the extra column.
Download PDF3-digit addition, no carrying · #2
A repeat page at the same guaranteed difficulty, useful when three columns are still one column too many.
Download PDF3-digit addition with carrying · #1
The full algorithm: every problem carries out of the ones and again out of the tens, which is where most of the slips happen.
Download PDF3-digit addition with carrying · #2
A second page of double carries, because this is the step that needs repeating rather than explaining again.
Download PDFAdding three numbers · #1
Three numbers stacked instead of two, which quietly teaches that a column can hold more than one carry.
Download PDFAdding three numbers · #2
Nine more three-addend columns, handy for the child who adds the first pair correctly and then forgets the third number.
Download PDFAdding three 3-digit numbers
Three hundreds-sized numbers in one column, the longest addition on this page and a genuine test of neat handwriting.
Download PDFDoubles and near doubles · #1
Each row puts 6 plus 6 next to 6 plus 7 on purpose, so the second answer is one step from the first rather than a fresh calculation.
Download PDFDoubles and near doubles · #2
The same strategy carried into the teens, where doubling 14 is a mental habit worth having before column addition arrives.
Download PDFNumber bonds to 10
Six part and whole diagrams for the number ten, the set of pairs worth knowing by heart before anything else.
Download PDFNumber bonds to 20
Twenty split six different ways, the bridge between knowing the pairs to ten and using them past the tens boundary.
Download PDFNumber bonds to 100
One hundred broken into two parts, the mental step behind giving change and behind every rounding shortcut later on.
Download PDFAddition on a number line to 20
Four number lines with every tick marked, so the sum is something you walk along rather than something you recall.
Download PDFAddition on a number line to 50
The ticks now stand for five, so the jumps have to be counted in groups instead of one at a time.
Download PDFAddition on a number line to 100
A hundred-long line where the efficient route is one big jump of tens and a small one after it.
Download PDFAdd across and down to 10
Four little grids where the corner total has to come out the same whichever way you work it, which is a built-in answer key.
Download PDFAdd across and down to 20
The same self-checking grids with teen numbers, where a wrong corner sends you back to find which row went astray.
Download PDFBalancing addition to 20
Both sides of the equals sign carry a sum, which is the page that stops a child reading the equals sign as an instruction.
Download PDFBalancing addition to 100
Two-digit balances, where guessing stops working and the total has to actually be found first.
Download PDFTrue or false: sums to 20
Ten number sentences, five of them wrong on purpose: marking somebody else's work is a different skill from doing your own.
Download PDFTrue or false: sums to 100
Two-digit statements to check, where a wrong answer is usually only one carry away from a right one.
Download PDFAddition speed drill to 10
Forty facts inside ten on one page, small print and no answer boxes: this one is about recall speed, not about method.
Download PDFAddition speed drill to 20
The classic forty-fact minute page for sums within twenty, the standard measure of whether the facts are automatic yet.
Download PDFAddition speed drill to 50
Forty two-digit sums under fifty, fast enough to be mental but big enough that guessing shows up immediately.
Download PDFAddition speed drill to 100
The hardest drill on the page: forty sums reaching a hundred, best given once the written column is already reliable.
Download PDFAdd 10 in your head
Sixteen numbers run through one rule, so the pattern in the tens digit becomes obvious before anybody explains it.
Download PDFAdd 20 in your head
Adding two tens at once, the natural follow-up once adding a single ten no longer needs any thought.
Download PDFAdd 100 in your head
Three-digit numbers with only the hundreds digit changing, which is place value doing all the work for you.
Download PDFAdd left to right to 30
Ten chains of three numbers, solved one step at a time, which is where children first have to hold a running total in their head.
Download PDFAdd left to right to 100
Longer chains with two-digit numbers, where losing the running total costs the whole answer and not just one digit.
Download PDFWhat is on each addition worksheet
The core practice pages carry twelve problems each, in big clear print with no clutter and no cartoon distractions, and every page has a name and date line at the top so it can go straight into a folder or a homework pile. The problems are set vertically, in a column, which is how addition is taught and how it will later be written out for two and three digit sums.
Work through them in order
Take the number ranges in sequence: sums to 5, then to 10, then to 20, then the two-digit and three-digit pages. Because the answer boxes are large and the layout never changes, a child who has done the first sheet already knows how to do the last one, and the only new thing on the page is the arithmetic. That is the point of a worksheet series.
More than one way to practise
Beyond the vertical grids there are horizontal rows, missing-addend pages, number lines to jump along, number bonds, add-across-and-down puzzles, balancing equations, true or false checking pages, timed fact drills and word problems. If the plain grids have stopped teaching anything, change the format rather than the topic. Subtraction mirrors this whole set in our subtraction worksheets, and the ladder starts earlier with counting and picture sums in our kindergarten math worksheets.
Frequently asked questions
What grade level are these addition worksheets?
Ages 5-8, so kindergarten through second grade depending on your curriculum. Sums to 10 are typical kindergarten and first-grade work, sums to 20 land in first and second grade, and column addition with carrying is second grade and beyond. Only the drill sheets are meant to be timed, and they say so on the page.
Do the worksheets come with an answer key?
No, there is no separate answer sheet. Each page is a single printable worksheet, and with twelve single-digit sums the answers can be checked at a glance or, better, checked by the child with counters or a number line.
Is this free for classroom and homeschool use?
Yes, and you can print unlimited copies for a class, a homeschool, a library or a tutoring session at no cost and with no sign-up. Selling the sheets or re-uploading them to another site is the only thing that is off limits.
