A few things before you print.
Are these worksheets free?
Yes. Create and download as many worksheets as you need for personal or classroom practice. No account or email address is required.
Can I include an answer key?
Yes. Select Include answer key to add a separate page with answers. You can also download the answer key on its own.
Can I print on A4 paper?
Yes. Choose A4 before downloading. Both A4 and US Letter layouts use printer-safe margins. Print at actual size, or 100%, in your PDF viewer.
How do I get a different set of questions?
Use New problems to change the seed. Keep the same seed and settings when you need to reproduce a page.
How should I choose the grade?
Grade labels are starting points. Ask for an estimate or a second way to check one answer. Keep the selected skill focused before increasing the number of items.
Are fraction answers simplified?
Yes. Addition and simplification answers use their lowest terms. Comparing fractions produces <, > or =. This generator uses like denominators for addition.
