First grade math is a significant year for young learners, who will start to build on the basic mathematical knowledge learned in kindergarten. By first grade, students should be able to identify basic shapes, describe measurable attributes such as length, width, and height, and understand the concepts of addition ("putting together") and subtraction ("taking away").

There are some big differences between kindergarten and first grade math standards. Students at a first grade level are expected to move beyond a mere understanding of numbers and know how to independently reason with numbers.

In first grade, children are introduced to time, money, and the meaning of numbers greater than those they can count. First graders begin solving simple addition and subtraction problems. They learn to skip count by 2s, 5s, and 10s—a skill that will help them later when solving math equations. They also begin to work with 2- and 3‑dimensional geometric shapes.

First grade math students are expected to be able to measure length, tell time, and represent and interpret data. Additionally, they should be able to use place value concepts to add and subtract, and know how to represent and solve simple addition and subtraction problems.

The Mathseeds program fully covers grades K–3 math skills, featuring 50 lessons per grade level.

Lessons 51–100 feature Mango the monkey and friends as they introduce and explore different math concepts. Children learn to count to 100, order numbers, and identify ordinal numbers. They develop an understanding of place value including regrouping, and also practice their subtraction skills.

Students learn how to add and subtract to 10, and then within 100. Strategies include counting on, counting back, near doubles, and using number fact families. They learn how to skip count by 2s, 5s, and 10s, as well as the early multiplication and division skills of grouping and sharing.

Later, students learn to identify bills and coins, and use addition to find amounts of money. They explore fractions, focusing on wholes, halves, and fourths. Students continue to investigate the features of 2D shapes and 3D objects. They follow simple directions to a particular location and learn to read clocks to the half‑hour. They also work with early chance concepts, tally charts, and simple picture graphs.
