3rd Grade Math Topics Covered

StudyPug covers all 25 core topics in Rhode Island's 3rd grade math curriculum, fully aligned to Rhode Island Math Standards. From multiplication and division to fractions and geometry, every lesson is designed to match exactly what students learn in Rhode Island classrooms.

Multiplication and Division

3rd grade is when students first learn multiplication and division. StudyPug's video lessons walk through interpreting products of whole numbers, using multiplication and division within 100 to solve word problems, and applying properties of operations as strategies. Students also practice fluently multiplying and dividing within 100 — a key skill for the RICAS assessment.

Fractions

Rhode Island 3rd graders are introduced to fractions as numbers. StudyPug covers understanding a fraction as one part of a whole, representing fractions on a number line, and comparing fractions by reasoning about their size. These foundational lessons prepare students for more advanced fraction work in 4th grade.

Place Value and Operations

Students in 3rd grade build on their number sense by rounding whole numbers to the nearest 10 or 100, fluently adding and subtracting within 1000, and multiplying one-digit whole numbers by multiples of 10. StudyPug breaks each of these skills into clear, step-by-step video lessons.

Measurement and Data

  • Tell and write time to the nearest minute
  • Measure liquid volumes and masses using standard units
  • Draw scaled picture graphs and bar graphs
  • Generate measurement data using rulers marked with halves and fourths of an inch

Geometry and Area

3rd grade introduces the concept of area for the first time. StudyPug covers recognizing area as an attribute of plane figures, measuring area by counting unit squares, relating area to multiplication and addition, and solving problems involving perimeters of polygons. Students also learn to identify shared attributes of shapes and partition shapes into equal parts.
