1st Grade Math Resources

Support first grade learners as they build key math skills with Education.com’s collection of over 2,000 printable worksheets, lesson plans, hands-on activities, and more. Designed to align with Common Core State Standards, these resources help students strengthen foundational math understanding through engaging, age-appropriate activities.

First graders begin developing number sense and operational fluency by practicing mixed addition and subtraction, exploring properties of addition, relating addition and subtraction, and solving a variety of addition and subtraction word problems within 20. Students then expand their place value understanding by exploring two-digit numbers, breaking them into tens and ones, and comparing pairs of two-digit numbers. These skills provide the foundation for adding within 100 and subtracting multiples of 10 from two-digit numbers.

Our first grade measurement and data resources build on kindergarten concepts to help learners progress, while time resources introduce telling time in hours and half-hours on both digital and analog clocks. Geometry worksheets encourage spatial reasoning with two- and three-dimensional shapes and present early fraction concepts in an approachable way.
