New Hampshire 1st Grade Math: Topics and Skills

First grade math in New Hampshire follows the NH Mathematics Model Competencies, covering a wide range of foundational skills. Students work on addition and subtraction within 20, understanding place value with two-digit numbers, basic measurement, telling time, and recognizing shapes. These skills prepare students for the more advanced math concepts they will encounter in 2nd grade and beyond.

Addition and Subtraction in 1st Grade

A major focus of 1st grade math is developing fluency with addition and subtraction. New Hampshire students learn to:

  • Use addition and subtraction within 20 to solve word problems
  • Add three whole numbers whose sum is 20 or less
  • Apply properties of operations as strategies to add and subtract
  • Understand subtraction as finding an unknown addend
  • Demonstrate fluency for addition and subtraction within 10

StudyPug's video lessons walk through each of these skills step by step, with worked examples your child can follow along with at home.

Place Value and Number Sense

1st grade students in New Hampshire build a solid understanding of two-digit numbers. Key topics include:

  • Understanding that two-digit numbers represent tens and ones
  • Counting to 120 starting from any number
  • Comparing two-digit numbers using >, =, and <
  • Adding within 100, including adding a two-digit and a one-digit number
  • Finding 10 more or 10 less than a number mentally
  • Subtracting multiples of 10 from multiples of 10

Measurement, Time, and Data

New Hampshire 1st graders also explore measurement and data concepts aligned to the NH Mathematics Model Competencies. Students order objects by length, express lengths in whole number units, tell time in hours and half-hours on analog and digital clocks, and organize data into up to three categories.

Geometry in 1st Grade

Geometry topics in 1st grade include distinguishing defining from non-defining shape attributes, composing two- and three-dimensional shapes, and partitioning circles and rectangles into two and four equal shares. These concepts build spatial reasoning skills that support later math learning.
