# First Grade Math Worksheets about Addition, Rounding, and Number Sense

Welcome to the first grade math page at TLSBooks. This page features first grade math activities related to number sense, addition, rounding, and estimation practice.

Subsequent first grade math pages include subtraction and mixed operations and geometry and measurement.

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.

Your child or students should begin or continue to learn about coins and their value. This is a great time to play store with real money and encourage recognition, counting, and addition of pennies, nickels, dimes, and quarters.

Ideally, addition skills should be practiced daily and practice could include reviewing flash cards, playing games, and completing worksheets. Students should be able to add two 2-digit numbers without regrouping and add three numbers with sums to 30. These skills are very important and will help build a solid foundation for future math success.

Depending on your child's abilities, you may wish to review these kindergarten worksheets and second grade math worksheets for additional math practice sheets.
