1st Grade Math in Maryland

Maryland 1st grade math is built on the Maryland College Career Ready Standards. Students move from basic counting into real addition and subtraction, learning to solve word problems, understand place value, and begin measuring lengths and telling time. StudyPug covers every one of these skills with clear video lessons and practice problems your child can use at home.

Addition and Subtraction in 1st Grade

A big focus in 1st grade is adding and subtracting within 20. Students learn to solve word problems, add three whole numbers, and understand how addition and subtraction relate to each other. They also explore the properties of operations and begin to develop fluency within 10. StudyPug's video lessons walk through each of these concepts step by step.

Place Value and Number Sense

Maryland 1st graders learn that two-digit numbers are made of tens and ones. They count to 120, compare two-digit numbers using >, =, and <, and practice adding within 100. Students also learn to mentally find 10 more or 10 less than any two-digit number — a key skill for 2nd grade math.

Measurement, Time, and Data

  • Order and compare objects by length using a third object as a reference
  • Measure length by counting whole unit lengths
  • Tell and write time in hours and half-hours on analog and digital clocks
  • Organize and interpret data sorted into up to three categories

Geometry in 1st Grade

1st graders in Maryland learn to identify defining attributes of 2D and 3D shapes, compose shapes to create new ones, and partition circles and rectangles into equal shares. These early geometry ideas prepare students for the more advanced shape and fraction work in 2nd and 3rd grade.
