First-Grade Math Worksheets

This page features first-grade math activities related to number sense, rounding, and estimation.

First grade is an extremely important year in the mathematical development of your child. By the end of this year they should have the ability to skip count past 100, read and write numbers to 100 (or preferably to 1,000), and represent a number of objects with a written numeral. First graders should continue working with patterns in an effort to improve problem solving skills.
