About math worksheets for 1st graders

First grade math is a big year. Children move from counting objects to adding and subtracting within 20 with real strategies, they count to 120, and they learn that a two-digit number is made of tens and ones. These math worksheets for 1st graders follow the year in that order.

The year has four big ideas. Children add and subtract within 20, solve word problems, and know their facts within 10 quickly. They understand place value: tens and ones, comparing two-digit numbers, adding within 100 and finding 10 more and 10 less. They measure length with small units and tell time to the hour and half hour. And they work with shapes and with halves and fourths.

Practice pages are made fresh from each skill, so most come as Sheet A, B and C with new problems for extra practice. Every page with right answers has an answer key on page 2, and all pages print in black and white on US Letter or A4 with half-inch margins.

Questions

What math should a 1st grader know?

By the end of 1st grade, children add and subtract within 20 and know their facts within 10 quickly, solve simple word problems, count to 120, understand tens and ones, compare two-digit numbers, add within 100, tell time to the half hour, measure with units and know basic shapes.

How can I help my 1st grader with math at home?

Keep it short and regular: a few minutes of facts most days, counting from different numbers, and talking about math in daily life, like how many more forks we need. Use a worksheet to practice the skill you just talked about.

Why are there Sheet A, B and C versions?

The practice pages are generated from each skill, so each version has new problems at the same level. Use one to practice and another a few days later to check that the skill has stuck.

Are there answer keys?

Yes. Every page with right answers has an answer key on page 2 of the PDF.
