Addition Drill Worksheets
Addition is the first algorithm children learn and the one every later operation leans on. These drill sheets follow the Common Core arc: sums within 5 and 10 in kindergarten, fact fluency within 20 across grades 1 and 2, two- and three-digit column addition with regrouping in grades 2 and 3, and the full standard algorithm on four- and five-digit numbers in grade 4.
Every sheet comes in three versions with the same layout and fresh numbers, so a student who has seen Set A gets a genuinely new page in Set B. Timed drills carry a timer box for fact fluency; vertical sheets stack the operands over a rule with room to write the carried digit; missing-number sheets put the blank in any of the three positions so addition and subtraction are learned as one relationship.

Addition on this site runs from Kindergarten to grade 4: 29 worksheets across five grades and six formats (drill, timed drill, missing number, mixed review, vertical format, and word problems), each in three versions, for 2,454 problems in all with every answer keyed. Eight of the sheets were first published on MathSheetLab and are kept here as Set A of their cell, with Sets B and C derived from them.
Grade by grade: Kindergarten works on sums within 5 and then within 10, and the pairs that make ten; Grade 1 works on fact fluency within 20, three addends, and two-digit plus one-digit numbers; Grade 2 works on two-digit addition within 100 with regrouping, and a first look at three-digit sums; Grade 3 works on three-digit column addition with regrouping in more than one place; Grade 4 works on the standard algorithm on four- and five-digit numbers.
Focus: sums within 5 and then within 10, and the pairs that make ten.

The six formats
- Drill. Straight practice, 20-40 problems. A straight run of sums is where regrouping becomes routine rather than an event.
- Timed Drill. Fact fluency, 50-100 problems, timer box on sheet. Fact recall has to be automatic before column addition can be, and a timed page is the only honest test of automatic.
- Missing Number. Solve for the blank in any position. A blank on the left or in the middle turns addition into its own inverse and builds the fact-family idea that subtraction rests on.
- Mixed Review. Assorted problem shapes from the operation. Alternating shapes stops a student from running one procedure on autopilot down the page.
- Word Problems. Story problems in real-world contexts. Deciding that a situation calls for addition is a different skill from adding, and it needs its own practice.
- Vertical Format. Column arithmetic with regrouping lines. Stacked operands make the place-value columns visible, which is what regrouping actually depends on.
