At a glance

The 1st grade math worksheets makes a fresh printable practice sheet in seconds. Mixed 1st grade practice: addition and subtraction within 20 plus place value. Every time you change a setting, the page rebuilds instantly, so you can print a different sheet for every group or lesson.

How the 1st grade math worksheets works

This 1st grade math worksheets assembles a complete printable page in the browser, and nothing is saved or repeated between visits.

Choose the problem type — Mixed review, Addition, Subtraction and Place value — then set the difficulty, how many problems you want and how many columns they sit in. The preview updates as you change each setting, so the page you see is exactly the page that prints.

The answer key is optional; when it is on, it prints on a separate page in the same order as the problems. Both US Letter and A4 are supported, and the layout is locked to a safe printable area so nothing is cut off.

Ways to use 1st grade math worksheets in class and at home

Mixed 1st grade practice: addition and subtraction within 20 plus place value. Because the problems regenerate, the same 1st grade math worksheets covers a warm-up on Monday, a homework sheet on Wednesday and a quick check on Friday without any of them repeating.

Keep the problem count low for a timed drill and raise it for a review packet. Printing several sheets at different difficulty levels is the quickest way to differentiate without preparing separate lessons.

What to look for when marking

Mixed grade-level review works best when the first few problems are comfortable, so start a difficulty level below where you think the class is.

Marking against the printed answer key is quicker than working the problems again, and it lets students self-check before they hand anything in.
