Addition worksheets
Addition is not one skill but a sequence of them, and children stall when a sheet skips a rung. These free printable worksheets follow the whole path, from counting two groups of pictures to carrying in a written two-digit sum.

Addition worksheets, easiest first
Each sheet assumes the one above it is comfortable. Start where your child is, not at the top.- + = __ Picture addition Child does: Count two picture groups to find the total. See this worksheet
- 8 + __ = 10 Number bonds and make ten Child does: Fill the missing part that completes the whole. See this worksheet
- 4 + 3 = __ Addition within 10 Child does: Solve written addition facts with small numbers. See this worksheet
- 8 + 7 = __ Addition within 20 Child does: Solve addition facts that cross ten. See this worksheet
- 7 + __ = 15 Missing addends Child does: Find the addend that completes the sum. See this worksheet
- 46 + 32 = __ Addition without regrouping Child does: Add place by place without carrying. See this worksheet
- 37 + 15 stacked Vertical addition Child does: Add two-digit numbers in stacked columns. See this worksheet
- 27 + 18 = __ Addition with regrouping Child does: Add two-digit numbers that require regrouping. See this worksheet
How addition develops
The first addition a child understands is counting: put the groups together and count them all. Picture addition keeps that honest — the objects are on the page to be touched and tallied, so a sum is a thing that happened rather than a fact to memorize.
The strategies come next, and they are what separate fluent children from slow ones. Counting on means starting from the larger number instead of from one. Number bonds build the make-ten move — 8 + 7 becomes 8 + 2 + 5 — which is the single most useful trick for sums that cross ten. Doubles and near doubles cover a surprising share of the remaining facts: a child who knows 7 + 7 gets 7 + 8 nearly free.
Only after facts within 20 are quick does written two-digit addition make sense. Regrouping is a place-value idea, not a new addition idea: ten ones become one ten and move columns. A child still counting on their fingers for 8 + 7 will not learn carrying from a carrying worksheet — they will learn it from finishing the earlier rung.
