Are these 4th grade math worksheets really free?

Yes. Every sheet in this section is free to generate and free to print, with no account, no email address and no download step. The pages carry advertising; that is the whole business model.

Will these print on A4 as well as US Letter?

Yes. These 4th grade math worksheets use a relative layout rather than fixed inches, so nothing is clipped on either paper size when print scaling is left at 100%.

Which worksheet should I start with?

Start with the skill the child is working on in class this week, not the one their grade number suggests. If a sheet takes more than fifteen minutes, drop back one link.

Do the worksheets come with answers?

Every one of them. The answer key is generated together with the problems and prints on its own page, so a child can work first and mark afterwards.

How to choose a worksheet

If a sheet turns out too easy or too hard, move one link along rather than adding more problems. The difficulty steps between these 4th grade math worksheets are deliberately small, which is the point of having so many of them.

The explanations attached to these 4th grade math worksheets are written for the adult, not the child: what the skill is, where it breaks down, and what to look at when an answer comes back wrong.

There is no account, no email address and no download step anywhere in this section. The worksheet is generated in your browser and goes straight to the printer or into a PDF file.

Every page listed under 4th grade math worksheets prints on US Letter and on A4 without clipping, and every one carries an answer key on a separate sheet so a child can work first and mark afterwards.

A routine that works

When a skill is secure, use a mixed review sheet to check that it survives being taken out of context. That is where most apparent mastery turns out to be partial.

Mark every sheet the day it is done. A sheet marked a week later tells you a score; one marked immediately tells you which step went wrong and which of these 4th grade math worksheets to print tomorrow.

Write the time taken and the score at the top of each sheet. Two weeks of those two numbers is a better progress report than any single test, and it costs five seconds a day.
