Illinois 3rd Grade Math Topics
3rd grade math in Illinois covers a wide range of foundational skills. Students work through multiplication and division, fractions, place value, measurement, data, area, and geometry. All topics follow the Illinois Learning Standards for Math, so every lesson on StudyPug connects directly to what Illinois schools teach.
Multiplication and Division
A major focus of 3rd grade math is understanding multiplication and division. Students learn to interpret products of whole numbers, solve word problems using multiplication and division within 100, and apply properties of operations. They also work on fluently multiplying and dividing within 100 — a key skill for the IAR assessment.
Fractions
Illinois 3rd graders are introduced to fractions as numbers. Students learn to understand a fraction as part of a whole, place fractions on a number line, explain fraction equivalence, and compare fractions by reasoning about their size. These concepts prepare students for more advanced fraction work in 4th grade.
Measurement and Data
3rd grade measurement topics include telling time to the nearest minute, measuring liquid volumes and masses, drawing scaled picture and bar graphs, and measuring lengths to the nearest half and quarter inch. These real-world skills connect math to everyday life.
Area and Geometry
Students explore area as an attribute of plane figures, measure areas by counting unit squares, and relate area to multiplication and addition. They also solve perimeter problems and identify shared attributes of shapes in different categories.
- Multiplication and division fluency within 100
- Fractions on a number line and fraction equivalence
- Measurement with standard units
- Scaled graphs and data representation
- Area, perimeter, and geometry concepts
Preparing for the IAR
Illinois 3rd graders take the IAR (Illinois Assessment of Readiness) math test. StudyPug covers every topic tested so students can build confidence before test day. Each video lesson is followed by practice problems that mirror the types of questions students see on the IAR.
