Grade 1 Math Worksheets — Free Printable Generator
By the end of Grade 1, most children are expected to add and subtract fluently within 20, understand place value up to 100, and begin recognising doubles. These worksheets cover all of that, and because you control the number ranges yourself, you can match the difficulty precisely to where your child or student is right now — not where the textbook assumes they should be.

Addition within 20
Moving from single digits to two-digit sums is the core Grade 1 milestone. The Addition 1–20 worksheet is ideal here — set both ranges to 1–10 for sums up to 20.
Subtraction within 20
Subtraction always follows addition in the learning sequence. The generator ensures no negative answers, so every problem stays age-appropriate.
Telling time to whole & half hours
Grade 1 introduces telling time on analog clock faces to the hour and half-hour (:00 and :30).
