Fourth Grade Math Content


The Baltimore County Public Schools elementary mathematics program is designed so that each student has access to rigorous instruction and engages in the habits of mind of proficient mathematical thinkers.

In Grade 4, instructional time should focus on three critical areas: (1) developing understanding and fluency with multi-digit multiplication, and developing understanding of dividing to find quotients involving multi-digit dividends; (2) developing an understanding of fraction equivalence, addition and subtraction of fractions with like denominators, and multiplication of fractions by whole numbers; (3) understanding that geometric figures can be analyzed and classified based on their properties, such as having parallel sides, perpendicular sides, particular angle measures, and symmetry.

Proficient Mathematical Thinkers

  • Make sense of problems and persevere in solving them.

  • Reason abstractly and quantitatively.

  • Construct viable arguments and critique the reasoning of others.

  • Model with mathematics.

  • Use appropriate tools strategically.

  • Attend to precision.

  • Look for and make use of structure.

  • Look for and express regularity in repeated reasoning.


(1) Students generalize their understanding of place value to 1,000,000, understanding the relative sizes of numbers in each place. They apply their understanding of models for multiplication (equal-sized groups, arrays, area models), place value, and properties of operations, in particular the distributive property, as they develop, discuss, and use efficient, accurate, and generalizable methods to compute products of multi-digit whole numbers. Depending on the numbers and the context, they select and accurately apply appropriate methods to estimate or mentally calculate products. They develop fluency with efficient procedures for multiplying whole numbers; understand and explain why the procedures work based on place value and properties of operations; and use them to solve problems. Students apply their understanding of models for division, place value, properties of operations, and the relationship of division to multiplication as they develop, discuss, and use efficient, accurate, and generalizable procedures to find quotients involving multi-digit dividends. They select and accurately apply appropriate methods to estimate and mentally calculate quotients, and interpret remainders based upon the context. 

 

(2) Students develop understanding of fraction equivalence and operations with fractions. They recognize that two different fractions can be equal (e.g., 15/9 = 5/3), and they develop methods for generating and recognizing equivalent fractions. Students extend previous understandings about how fractions are built from unit fractions, composing fractions from unit fractions, decomposing fractions into unit fractions, and using the meaning of fractions and the meaning of multiplication to multiply a fraction by a whole number. 

 

(3) Students describe, analyze, compare, and classify two-dimensional shapes. Through building, drawing, and analyzing two-dimensional shapes, students deepen their understanding of properties of two-dimensional objects and the use of them to solve problems involving symmetry.


 

Fourth Grade Math Curriculum

 

In fourth grade, students focus on multiplication and division with multi-digit numbers, fractions, and geometry. Throughout the year they: 

  • Find factors and multiples of different numbers 
  • Compare fractions and break fractions into smaller parts 
  • Compare decimal numbers and find decimal and fraction equivalents 
  • Develop efficient strategies for multiplying and dividing multi-digit numbers 
  • Calculate area and work with volume 
  • Measure and draw angles using protractors 

 

The math might sometimes seem unfamiliar or different than you remember, but there are many ways you can help! 

 

  • Invite your child to talk about the math by asking questions like, Did you do a problem like this at school? How did you think about it?
  • Focus on the pictures. Bridges uses visual models to make the mathematics accessible to all learners. Talking about the pictures is a great way to get started. Ask questions like, What do you notice about this picture? Where do you see the numbers in this picture? Can we use the picture to help solve the problem?”

By being open to learning and talking with your child, you can help your child develop strong skills and a love of math.
