About this resource
Description
Adding nine is a fact family that trips up many young learners, because every sum crosses ten. This adding nine matching worksheet gives first graders steady practice with sums from 11 to 20, so 9 + 9 feels just as easy as 2 + 9. A handy trick is to add ten and take one away, and this page gives children plenty of chances to try it until the facts feel automatic.
The page has two parts. Part A sets six addition problems in blue pills down the left side, and students draw a line from each problem to its sum in the scrambled column on the right. The nine switches sides from problem to problem, so children see that 9 + 4 and 4 + 9 give the same answer. Part B gives four more add-nine problems for students to solve on their own and write in the answer boxes. Use this adding nine matching worksheet as a warm-up, a math center, homework, or a quick check after a lesson on addition facts.
What’s Included
- One printable adding nine matching worksheet (1st Grade)
- Part A: six add-nine facts to match to their sums
- Part B: four add-nine problems with answer boxes
- A complete answer key on the second page
Why It Helps Kids
First, matching lets students check their own thinking: every sum in the right column is used exactly once, so a leftover number is a clue to look again. Second, every problem crosses ten, which builds the make-a-ten strategy that first graders need for all their teen facts. Third, the written Part B moves students from recognizing an answer to producing it, which is the step that makes a fact stick.
Ideas for Teachers and Parents
Before the page, model 7 + 9 with ten frames: fill one frame with nine counters, move one over from the seven to make ten, and see that 10 + 6 = 16. After students finish, ask them to explain one answer out loud using the add-ten, take-one-away trick. This first grade addition worksheet also pairs well with the Adding 9 Song and a quick oral fact drill.
