Addition Worksheets for Grade 1 โ€” Free Printable PDFs

Generate free addition worksheets for 1st graders: sums up to 10, then up to 20, with an answer key on a separate page. The generator opens with addition selected and sums up to 20, so all that is left is to pick the number of problems and print.

What 1st Graders Learn in Addition

  • Adding single-digit numbers (sums to 10, then to 20)
  • Counting on from the larger number
  • Making ten strategy (e.g., 8 + 5 = 8 + 2 + 3 = 13)
  • Addition word problems with "joining" and "adding to" situations
  • Understanding the equals sign and the commutative property (3 + 6 = 6 + 3)

How to Use These Worksheets

  1. Click "Generate Grade 1 Addition Worksheets": Arithmetic Drills opens with addition (+) selected and a Number Range Limit of 20.
  2. With "Limit by: Result", no sum goes over the limit. Choose 10 for beginners, so every problem has two single-digit numbers and a sum of 10 or less.
  3. Set the Number of Questions: 10โ€“20 problems is plenty at this age.
  4. Keep the answer key and the name, date and result fields ticked, then click "Download PDF Worksheet".
  5. Print it. The share link brings back exactly the same worksheet later.

Tips for Teaching Addition in Grade 1

  • Use manipulatives (blocks, counters, fingers) before moving to abstract numbers.
  • Teach "counting on": for 3 + 8, start at 8 and count 9, 10, 11.
  • Practice "making ten": the pairs that make 10 are the foundation for mental math.
  • Keep sessions short (5โ€“10 minutes): young learners lose focus quickly.
  • Check the sheet together with the answer key and praise effort, not just correct answers.
