▸ Why It Matters
Doubles (1+1 through 9+9) are some of the fastest addition facts to memorize because there's only one number to remember, not two. This worksheet covers all nine doubles from 1+1 through 9+9, plus five "near-doubles" problems (1+2, 2+3, 3+4, 4+5, 5+6) that let your child immediately apply what they just memorized. Once doubles are automatic, they become a shortcut for solving near-doubles problems (like 4+5, which is just "double 4, plus 1") much faster than counting from scratch. Many children who struggle with addition later on never built this doubles foundation early — strengthening it now pays off for years, since doubles show up again in subtraction, multiplication (the 2x table), and even mental math with larger numbers.
▸ Getting Started
Work through the doubles column first (1+1 up to 9+9), having your child say each fact as a little chant while solving it ("two plus two, that's a double, makes four") — the rhythm and repetition of naming it specifically as a "double" helps the fact stick in memory faster than a plain number sentence. Once they've built confidence there, move to the five near-doubles problems at the bottom and encourage them to notice the pattern — ask "which double is this close to?" before they start counting. Some children like to draw a small dot or star next to problems they solved instantly, which turns memorization into a visible, satisfying progress tracker.
▸ If They Get Stuck
Use pairs of identical objects (two shoes, two hands, two of the same toy, two cookies split between two hands) to make the "same plus same" idea concrete — doubles are everywhere in daily life, and pointing that out makes the abstract fact feel familiar. If a near-doubles problem like 4+5 trips them up, cover the 5 and ask "what's 4+4?" first, then add one more — this bridges directly from what they already know instead of starting over. A common mistake is skip-counting incorrectly on fingers; if that happens, slow down and recount together rather than correcting abruptly.
▸ Praise Points
Praise fast recall on a doubles fact specifically: "You knew 5+5 instantly without counting — that's exactly what a memorized doubles fact looks like, and it'll help you with harder problems soon." Also celebrate when they successfully use a doubles fact to solve a near-doubles problem, since that shows real strategic thinking, not just memorization.
🎯What This Worksheet Builds
This worksheet focuses on doubles facts (1+1 through 9+9), helping your child memorize these paired-number sums as instant, no-counting answers. It also introduces five near-doubles problems (1+2, 2+3, 3+4, 4+5, 5+6) that build directly on the doubles your child just practiced, teaching the strategy of adjusting a known double by one instead of counting from scratch. Together these fourteen problems train both rote recall and early mental-math flexibility, a foundation that supports later subtraction, multiplication, and larger-number addition.
👉Next Step
Once doubles are automatic and your child can solve near-doubles problems confidently, move to Addition Practice 5 - Adding 1, which builds on the same "adjust a known fact" strategy. You can also keep reinforcing near-doubles by mixing in extra examples like 6+7 or 7+8 during everyday moments, such as counting snacks or toys, so the skill generalizes beyond this worksheet's specific problems.
