Free Printable K-5 Math Worksheets with Answer Keys

Need a fresh set of math problems before first period? This free math worksheet generator builds printable practice in seconds for kindergarten through fifth grade. Choose addition, subtraction, multiplication, division or a mixed review, then the exact skill: facts within 10 or 20, two-digit addition and subtraction with or without regrouping, 2-digit × 1-digit multiplication, or the 1–12 times tables. Switch to Telling Time for analog clock faces to the hour, half hour, quarter hour, five minutes or any minute. Every worksheet is new, so students can’t memorize the answers, and each PDF comes with a matching answer key for fast grading — perfect for morning work, homework, math centers, substitute plans and extra practice at home.

Create a worksheet in 3 steps

  1. Choose the skill. Pick Basic Arithmetic (addition, subtraction, multiplication, division or mixed, plus the number range) or Telling Time (and how precise the clocks are).

  2. Set up the page. Choose 12, 16, 20 or 24 problems per page, vertical or horizontal format, and whether to include Name & Date lines. Click Generate New Problems any time for a brand-new set.

  3. Print, share or project. Download the printable PDF in US Letter or A4 — page one is the student worksheet, page two is the answer key. Or open Classroom Presentation Mode to solve problems together on the board.

Ways to use it in your classroom

  • Morning work that’s always new

    Set up a 12-problem sheet for the skill you taught yesterday and print it before school. Click Generate New Problems for a different version each day, so students can’t copy last week’s answers. Keep the answer key page at your desk, or let early finishers check their own work.

  • Solve together on the board

    Open Classroom Presentation Mode and work a few problems with the class, thinking aloud about regrouping or the hands on a clock. Show answers lets students check the rest, and New problems gives a fresh set when you want a second round. Answers are hidden again each time you enter presentation mode.

  • Two versions for small groups

    Print one worksheet within 100 with no regrouping and one with regrouping, then hand each group the version that fits. Both look alike, so no one feels singled out. Second graders who finish the first set can move on to the regrouping set the same day.

  • Telling-time exit ticket

    After a clock lesson, choose Telling Time with 12 clocks at the level you just taught, such as quarter hour. Students write the time under each clock before they leave, and you sort the papers with the answer key in a few minutes to plan tomorrow’s groups.

Frequently Asked Questions

Are the worksheets aligned with grade-level standards?

The number ranges follow the progression used in Common Core classrooms: facts within 10 in kindergarten, within 20 in grades 1–2, two-digit addition and subtraction with and without regrouping in grade 2, and multiplication and division in grades 3–4. Subtraction never goes below zero, division always comes out even, and the regrouping options really do (or really don’t) need carrying and borrowing.

Can I make telling time worksheets?

Yes. Choose Telling Time and the generator draws analog clocks with hour and minute hands — to the hour, half hour, quarter hour, five minutes or any minute — with a blank for students to write the time. The hour hand moves between the numbers as the minutes pass, just like a real clock, and the answer key lists every time.

Can I use these worksheets for free in my classroom?

Yes. Every worksheet is free to print and copy for your classroom, homeschool or tutoring sessions, with no sign-up required. Generate as many versions as you like — each one is unique.

Can I make long division worksheets?

Yes. Choose Division with the vertical format and each problem appears in a long-division bracket, with the quotient written above the bar on the answer key. Pick 2-digit ÷ 1-digit, such as 84 ÷ 4, or Division Facts from the 1–12 tables. Every problem divides evenly, so there are no remainders to grade.

Should I choose the vertical or horizontal format?

Vertical stacks the numbers in columns, which helps students line up place value for two-digit addition and subtraction, and shows division in a long-division bracket. Horizontal writes each problem on one line, like 12 + 7 = ___, which suits fact practice and mental math. You can switch formats and download both versions of the same skill.

Can I make a mixed review worksheet?

Yes. Choose Mixed as the operation and pick a number range. Within 10 mixes addition and subtraction; from Within 20 up, the sheet also includes multiplication and division facts. The operations are spread evenly across the page and shuffled, so students have to read each sign before they solve.
