Missouri 3rd Grade Math: What Students Learn
Missouri 3rd grade math is a big year. Students move from basic addition and subtraction into multiplication, division, and fractions for the first time. These skills are the foundation for everything in 4th grade and beyond. StudyPug covers every topic in the Missouri Learning Standards Math for Grade 3.
Multiplication and Division
A major focus of 3rd grade math is learning multiplication and division. Missouri students learn to interpret products of whole numbers, use multiplication within 100 to solve word problems, and understand division as an unknown-factor problem. StudyPug has video lessons that walk through each concept step by step, with practice problems to reinforce every skill.
- Interpret products and quotients of whole numbers
- Solve word problems using multiplication and division within 100
- Apply properties of operations as strategies to multiply and divide
- Fluently multiply and divide within 100
Fractions
3rd grade is when Missouri students are introduced to fractions. They learn what a fraction means, how to place fractions on a number line, and how to compare fractions by reasoning about size. StudyPug breaks these concepts into clear, short lessons so students build a strong understanding before moving on.
- Understand a fraction 1/b as one part of a whole partitioned into equal parts
- Represent fractions on a number line diagram
- Explain equivalence of fractions and compare fractions by size
Place Value, Addition, and Subtraction
Missouri 3rd graders continue building number sense with place value. They round whole numbers to the nearest 10 or 100, and fluently add and subtract within 1,000 using strategies based on place value. They also multiply one-digit numbers by multiples of 10.
Geometry and Measurement
Students explore area and perimeter for the first time in Grade 3. They recognize area as an attribute of plane figures, measure area by counting unit squares, and solve real-world problems involving perimeters of polygons. They also work with time, liquid volumes, and masses using standard units.
- Tell and write time to the nearest minute
- Measure liquid volumes and masses using standard units
- Recognize area and measure it using unit squares
- Relate area to multiplication and addition
- Solve perimeter problems for polygons
Data and Graphs
3rd graders in Missouri learn to draw scaled picture graphs and bar graphs to represent data sets. They also generate measurement data by measuring lengths to the nearest half and quarter inch.
Preparing for the Missouri MAP Test
Missouri's MAP (Missouri Assessment Program) test includes 3rd grade math. StudyPug covers every Missouri Learning Standards Math topic assessed at Grade 3, so students can review specific skills and build confidence before test day.
